I believe this is the classic check valve within the fuel pump going bad. Pump is fine because it runs great after you start it. Once engine is off pressure drops due to bad check valve (fuel rail pressure drops and fuel goes back into tank) so not as much fuel immediately available at the next startup. Check valve is part of pump so have to replace whole unit. If you turn the key on once or twice before starting this primes the rails and will make it appear to be fine. It is just that initial prime is not enough. Thanks for sharing
My 2007 Tahoe only Prime's the pump once when you key it up it will not do it multiple times because it's a returnless system it does not want to overpressure it same with every other Tahoe after 07 I've looked at priming the fuel pump does not fix low fuel pressure in one of these
Thats not really true... because if it cranks the motor will usually run due to pulling fuel on its own. Fuel pumps go out all the time but still work sometimes with a tap or bump to get motor turning on the pump with power to it
I was thinking the same thing about. Maybe I just need a tuneup. So I change the plugs and wire. But it was still not starting on the first key turn. It turn out to be my fuel pump was bad. Replaced the pump and anything works fine now.
Robert, I need to do that also. I have done that to my 2000 Suburban. But this was a fuel pump issue. It was just not pumping enough pressure on start up. Thank for watching the video.
Only vid that I could find that included the start up - which sounds exactly like mine. Ordered fuel pump and hoping that resolves the issue. Thank you for the video good sir.
@@RobbySemperFi did it fix your problem? Did it give any codes before? I have the same sound and issue when i start my truck in the morning and then throughout the day it works perfect its only the start up issue when it gets cold
The bass hunter question is was changing your fuel pump complicated? I have the same issue and was going to have it done but it'll cost 600$ I'm sure I could do it just wanted to get some insight or tips! Thanks for the video
Zeek Rivera on the 10 point scale. It's about a 6 for one man. You have to run the gas in the truck low as you can. Pass the gas light coming on. At that point you still will about 3 to 5 gallons of gas still in the tank. You will need some car ramps and back the truck up on the ramps. So the rear of the truck is in the air. Then get your floor jack and a piece of wood about 2ft long. Place the wood on top of the jack. Jack up the jack and the wood under the gas tank to support the tank. Then you can remove the tanks metal straps that hold the tank to the truck. Then you disconnect all the gas lines and wires from the fuel pump. It is kind of hard to tell you what to do from here. Just because it's about it's two lines in the front of the tank and two in the back of the tank. The full hose where you full the tank with gas and two lines on top of the fuel pump. With two wire connections on the fuel pump. I hope that helps.
many shop offer a fuel injector purge. they can hook up on the fuel rail and clean the injectors to make sure the injectors are in top shape. my 05 avalanche had an issue with the vapor system and I had to change the solenoid. and purge valve.
My 06' Suburban always takes two tries to start and now it's been randomly stalling out . I suspect it's probably the fuel pump . When I press the Schraeder valve where the tester goes just a tiny bit of fuel came out I'm going to get a tester .
Gas is supposed to spray out when you depress Schrader valve at fuel rail you'll know it when it's good when it's bad a lil tiny squirt may come out or very faint stream not nearly good enough usually in tank fuel pump needs replacement have fun with that dropping the tank getting ring off and fuel lines without breaking them you have at least a weekend of fun ahead of you if you do it right and clean tank out... I've done too many from 96 to current caused by running tank empty too much I get it gas is expensive but swapping the pump is way more costly
I have an Escalade and exact same fuel pressure gauge and made exact same mistake. Directions say to put the Teflon tape. I was getting no pressure then after 3-4 cycles I got 60lbs however I can't get pressure to register anymore. My caddy also has white smoke that smells like raw fuel coming out of the tailpipe
@@XJRMANIAC That sounds like a fuel injector is stuck open or leaking. Possibly an ignition failure. A fuel pressure test would be a good start. Make sure it holds pressure and does not drop low immediately
Before you fixed this, did you ever have a code come up for an evap leak? I’m having same type issue with my ‘07 suburban not starting in the first key turn sometimes, and I get a code for evap leak whenever that issue gets more frequent.
But it started low cranking after replacing injectors and been like that since I did them I even went back and removed and installed the injectors and same thing. So I’m tried of it low cranking and not starting right up like it should
@@bryanalaniz4172 I had to replace my fuel pump to fix my problem. You can rent a fuel pressure gauge from the auto parts store and connect it to your fuel rail to see what is your fuel pressure on start up. The pressure has to be a certain psi to start your truck. You will have to look up that psi because I have for got but it’s around 45 to 55.
Crazy I'm the first one to say this, but those harbor freight diagnostic tools suck. As if troubleshooting a vehicle was not hard enough, gotta troubleshoot the diagnostic pressure tester as well...
Juan Cano You must not like Harbor Freight? Sounds like you have had some bad experiences with there tools. They are ok for one or two times. But I don't use them much.
The BassHunter believe it or not I actually like harbor freight a lot jajaja. I just purchased a 26" tall tool cabinet on sale for $295, large wrenches for alignments, impact sockets, and other stuff. I use Pittsburgh tools daily and work very well, plus have lifetime warranty. There are some stuff though that are not quality build and theres videos of those specifically like, brake bleeders, compression testers, and fuel pressure tester. As well theres other stuff that people can't get enough of like predator engines, compressors, floor jacks, welders, and more.
good morning how are you doing? Hey, I have a question I have the same problem on my vehicle. I already change the fuel pump and it’s doing the same thing watt. Was it finally on your vehicle
My problem was the fuel regulator us bad and it do not have enough psi to start the truck on the first turn of the key. But the regulator is build into the fuel pump. So, I changed my fuel pump and it fixed my problem. You may want to replace your crank shaft positioning sensor. If that's bad it will not start ether. It's located behind the starter. I replace that and my cam positioning sensor also before I replaced my fuel pump but that did not fix my problem it might fix yours. It is located on the front of the engine below the water pump. the sensor are about $50 each.
I am getting a steady 45 psi on my car 2011 suburban 5.3. I feel like its dumping fuel because my fuel gauge goes down more than normal. I see everyone else mention 50 to 60 at the rails but i am using my expensive x431 scan tool to check everything. All of a sudden after 1 month of using e85 its been extremely bad. Fuel gauge drops fast. I cant find no wet fuel leaks by the engine compartment. My mpg normal at 15 to 18. Now feels like 6. I am also using a scan gauge to read the mpgs and its not bad hwy is 18mpg both dash and scan gaugeii. What the hell is there a small leak some where only when its on?
Yes, that fuel pressure sounds a little on the low side. The fuel regulator is builded onto the fuel pump that is in the fuel tank. I had to replace my fuel pump to fix my problem. It would drive down the road fine but just had problems starting. Are you having trouble starting the truck?
Yes, it will. My truck ran fine after it started but I’m sure the truck computer is making changes to correct the low fuel pressure. Which will make the truck burn more gas. I had to replace the fuel pump to fix my problem.
The fuel is made into the fuel pump. It’s not like old silver regulators from back in the date. If you are having starting and you have changed the fuel pump you might want to look at your cam positioning sensor and your cam positioning sensor. They will also make you truck hard to start. I charged my sensors first and that did not fix my problem then I changed my fuel pump and that fixed my problem. You may have wanted to check the fuel pressure on the fuel rail before change your fuel pump. If the pressure was fine then you know it ‘s was something else. Like the sensors. Good luck.
Ola amigo como estas su video es de mucha ayuda yo tengo ese mismo problema en una suburban 2007 LT 1500 me pasa lo mismo ase 6 años cambien la pompa de gasolina por que se me apagaba pero ahora no prende al primer llabaso que logro aser cambio la pompa o que iso por favor me pudieras contestar thanks
I do notice this was uploaded over a year ago. do you remember what the issue was with you truck having this issue? I have a 07 avalanche doing the same thing trying to figure out what I need to do before I take it in to some pros.
My problem was the truck would not start on the first turn of the key. It would start on the second turn. So to make a long story short. I check the fuel pressure and the fuel pump was not making enough pressure on the first turn of the key to start the truck. So I had to replace my fuel pump and that fixed the problem. I help that helps.
On my truck. The problem was the fuel filter is made into the fuel pump.So you can not chance it. If that is the problem. There are no ways around. You have to replace the fuel pump. There is nothing else you can do. The fuel pressure regulator is made into the fuel pump also. So all the things that could be fuel related problems are made onto the fuel pump. That is why I just replaced the fuel pump and cut out all the other problem. But I replace the fuel pump myself. The fuel pump for your truck is $184 ACDELCO M10107 GM Original Equipment on Rock Auto. It is what it is. Sorry
That is a sure sign for bleed off that quick.is a bad diaphram in regulator..regulator is part of fuel pump assembly on that model year..55psi is normal..should not bleed off that quick..next time save your money and do a tool loaner program at local auto store...peace
I have the same problem with my 2005 avalanche not starting on the first key turn if it sits longer than 2 hours always the same problem but runs great always never starts on first key turn has no codes did ylu end up changing the fue pump and did that fix the problem
Yea ive done everthing tune up plugs wires check the evap system i guess the last thing to do is the fuel pump crazy runs great after that first start ive had the problem for about 2 years now and its my daily driver
Brandon Farmer The reason having to change the fuel pump is the fuel pressure regulator is builder into the fuel pump. That what you have to change the fuel pump.
DemBones1012 No, that was the crazy thing about that. It drove fine. Did not skip or lost any power. The fuel pump just did not have enough fuel pressure to start my truck on the first key turn. I changed the fuel pump and that fixed that problem.

Hi i have the same issue with my chevy 2013 2500 gas when i start it the first time it doenst start and then i try again and starts up fine do you think it might be the fuel pump ? It happens everyday
@@thebasshunter thank for the reply the weird thing is that it doesnt give me any check engine codes . it might still be the fuel pump because it runs fine and starts up fine during the day on and off its just the morning cold start it happens
colesdad2000 Most likely not. A lot of the cheap fuel pumps only last a year or two. Before they go out. That’s why you have to buy the OEM parts. They last the longest.
2006 gmc envoy denali xl 5.3L everything is built into the fuel pump.. The ODD thing is if it is cold outside.. it will also start on the first turn… could I be looking at a bad fuse block? Ive replaced that in the past too,
Not everyone can afford to pay double or more for tools. I am going through college and trying to keep my vehicle running myself because mechanics are out of my price range. I have worked on my vehicles for years and have bought a lot of tools at harbor freight. There is nothing wrong with them unless you are concerned with impressing other people with a brand name. Yes, they are made in China. So are craftsman, cobalt, and most of the other brands that aren't snap-on. Most of their tools have a lifetime warranty, which is more then you can say for a lot of the big box store tools now. I have a mix of all kinds and brands of tools in my tool box and I would put harbor freight up against any of them.
Harbor Freight tools work just fine. They are great value if you know what you need. As a test, buy a Harbor Freight and perform a side by side test with a brand name costing 4 times as much like Snap-on or Mikita. You will see that the Harbor Freight tools performs just as good and will give the same readings. You are like a lot of women; they buy the packaging/ image instead of the product and pay a lot more for less in damn near everything.
I have the same issue mine won't start till the second or third time and the pumps making a whining noise ..... I also got a cel for lean bank 1 and 2 also the same time the CEL comes on my stability link and trac control light show up and come and go .... I've read if the eng runs rough the stability trac light can come on too .... wondering if that happened to yours also thanks
Nick Hennebury Yes, my stability trac light came on when I first bought my truck about 3 years ago. I replaced the stability trac module that is located up the dashboard up the steering wheel. I don't know if that has anything to do with your truck running bad. You need a fuel pump. But my stability trac light still comes on and goes off for about 5 seconds about every 6 months. I don't pay much attentions to it.
That could be your crankshaft positioning sensor. I have a video where I replaced my thanking that was my problem with the long cranking time. But is was not the problem. But it is a little sensor on the bottom side of the engine above the starter. Or do some research on your camshaft positioning sensor. It my have something to do with it. I don’t know much about thing but I replaced mine also. These sensor are like $30 a piece. The camshaft positioning sensor is located on the front of the engine under the water pump. You can see it but you can feel it. I don’t have a video on the that sensor. Mostly likely one of these is your problem.
bigdaddy8896 I had that problem too. After I replaced the fuel pump. About a year later I was smelling gas fumes. And every time I would fill up with gas about a half of gallon with spill out. And I could not figure out where it was spilling from. I had to down my gas tank and the fuel regulator on the top of the fuel pump had popped out of the fuel pump. So I had a half an inch hole on the top of my fuel pump where gas was leaking out. So I had replace the pump again. But the pump was under warranty. So that could be something to think about.
BassHunter thanks bro. I still have the original in with 130,000 on it. When did they start putting the regulator in the pump, late 2003? I have a 2004 Z71.
randyusmc it was my fuel pump. It was not have pushing or holding enough pressure to start the truck on the first key turn. It would have to turn over several time to start. So I changed my fuel pump and it fixed that problem.
awesome thanks alot man my yukon I'd doing the same damn thing so I just ordered the ac Delco one. what brand did you get? I was going to try the 70 dollar replacement brand but read they leak.
randyusmc I got the AC Delco also. But I just had to replace that fuel pump again about two weeks ago. The pressure sensor popped out the top of the fuel pump. So it left a dime size hole in top of the pump. Every time I would fill it up. About a gallon of gas would Leak out.
D-NICE LEE It was my fuel pump. It was not producing enough fuel pressure to start the truck on the first key turn. So I replaced the fuel pump and that fixed my problem. The reason you have to replace the fuel pump is the fuel pressure regulator is build into the fuel pump. Sad I know but that how it is. Thanks for watching.
I was getting injector malfunction code on cylinder 6 and random misfire code I replaced all plugs, wires, cleaned all injectors and tested injector wires with noid light. I had to replace one injector and cleaned the rest and truck still runs like shit. White smoke and raw fuel. I also keep getting these same issues on the pressure gauge. I'm thinking fuel pump but it's a $300 + pump diy so I'm trying the simplest things first. It runs perfect when front end is jacked up but as soon as I let down on the jack right before my eyes it will huff and puff and jerk and knock and turn on engine light and pour white smoke out the exhaust that is thick and very suffocating. Fuel pressure regulator? Or pump? Any ideas please help!!!!
Jorge Vasquez sorry it has took me this long to get back with but I been fishing. But make problem was my fuel pump. Because me fuel regulator is made into my fuel pump. So you have to change the fuel pump to change the fuel regulator and the fuel filter. All that is made into the fuel pump. Sounds like your fuel regulator to me but I’m now a mechanic.
The BassHunter thank you so much for getting back to me on this. I was wondering if the regulator was a part of the pump because I could not find a single video or anything that showed me otherwise. And as far as the fuel filter being tied into the pump as well...I was thinking that to, but it makes it so much better to hear from someone that has went through it already. Everyone wants to scream compression test when I baby this truck and sometimes she runs fine. Thank you again so much and I appreciate it.
The BassHunter did you ever get thick white smoke from tailpipe that smelled like raw gasoline ? I'm sure it's the pump now because when it's jacked up in the front it runs fine but as soon as I let the jack down it starts bucking and puffing and misfiring .
Jorge Vasquez No, I never got the smoke. Maybe your truck’s computer is try to make up for the lack of fuel pressure and dumping to much gas in to a cylinder or two. But as for you jacking the truck up and it running fine. Is a mystery. I don’t know what that could be.
The BassHunter thank you for helping me troubleshoot. I think the jacking up the truck moves the fuel to the rear and "maybe" the skewer or "sock" that filters the gas or whatever filters inside there had something blocking fuel from getting in ....idk, but I do know ima get at it today and watching videos like yours makes it a heck of a lot easier. Thanks again.

I have the same problem with my 2005 avalanche not starting on the first key turn if it sits longer than 2 hours always the same problem but runs great always never starts on first key turn has no codes did ylu end up changing the fue pump and did that fix the problem
Yep, That is what I had to do also is replace the fuel pump.
Yea ive done everthing tune up plugs wires check the evap system i guess the last thing to do is the fuel pump crazy runs great after that first start ive had the problem for about 2 years now and its my daily driver
Brandon Farmer The reason having to change the fuel pump is the fuel pressure regulator is builder into the fuel pump. That what you have to change the fuel pump.
Brandon Farmer I want to say the Acdelco.
The BassHunter thanks alot
I think my foxbody mustang has the same issue, when you drove it around with low pressure was there a lack in power?
DemBones1012 No, that was the crazy thing about that. It drove fine. Did not skip or lost any power. The fuel pump just did not have enough fuel pressure to start my truck on the first key turn. I changed the fuel pump and that fixed that problem.
The BassHunter thanks for the quick reply I guess I'll have to do some more digging
DemBones1012 want to sell your fox body?
@@bowtiebuilding sorry buddy she's already gone. Got everything sorted out though she ran like a champ after but I wasn't a fan of the convertible top so I got rid of it. Plan on getting a notchback if I can at some point but that's slim pickins
Hi i have the same issue with my chevy 2013 2500 gas when i start it the first time it doenst start and then i try again and starts up fine do you think it might be the fuel pump ? It happens everyday
Yes, it was the fuel pump. I replaced the fuel and it fix my problem.
@@thebasshunter thank for the reply the weird thing is that it doesnt give me any check engine codes . it might still be the fuel pump because it runs fine and starts up fine during the day on and off its just the morning cold start it happens
@@thebasshunter should it give any codes? because mine doesnt pop up any codes at all and my 2013 fuel pump cost almost $600 at autoparts store
@@jasesitl4837 No, mine did not give any codes. But go to Rockauto.com you should be able to get the pump for cheaper there.
You need pipe dope on your fittings. Smh
I've replaced the fuel pump 3 times for this issue. I'm starting to wonder if I have a short that's wearing out the regulator fast
colesdad2000 Most likely not. A lot of the cheap fuel pumps only last a year or two. Before they go out. That’s why you have to buy the OEM parts. They last the longest.
@@thebasshunter I used AC Delco with lifetime Autozone warranty
colesdad2000 fuel pump control module bad? What kind of vehicle is it ?
2006 gmc envoy denali xl 5.3L everything is built into the fuel pump.. The ODD thing is if it is cold outside.. it will also start on the first turn… could I be looking at a bad fuse block? Ive replaced that in the past too,
colesdad2000 are you sure there is no fuel pressure regulator in the engine bay somewhere ? Also do you have a fuel pressure gauge ?
Harbor Freight? For tools....you might as well use one from playschool...smh...I wouldn't buy bottled water from harbor freight.
Not everyone can afford to pay double or more for tools. I am going through college and trying to keep my vehicle running myself because mechanics are out of my price range. I have worked on my vehicles for years and have bought a lot of tools at harbor freight. There is nothing wrong with them unless you are concerned with impressing other people with a brand name. Yes, they are made in China. So are craftsman, cobalt, and most of the other brands that aren't snap-on. Most of their tools have a lifetime warranty, which is more then you can say for a lot of the big box store tools now. I have a mix of all kinds and brands of tools in my tool box and I would put harbor freight up against any of them.
Harbor Freight tools work just fine. They are great value if you know what you need.
As a test, buy a Harbor Freight and perform a side by side test with a brand name costing 4 times as much like Snap-on or Mikita.
You will see that the Harbor Freight tools performs just as good and will give the same readings.
You are like a lot of women; they buy the packaging/ image instead of the product and pay a lot more for less in damn near everything.
I have the same issue mine won't start till the second or third time and the pumps making a whining noise ..... I also got a cel for lean bank 1 and 2 also the same time the CEL comes on my stability link and trac control light show up and come and go .... I've read if the eng runs rough the stability trac light can come on too .... wondering if that happened to yours also thanks
The rail is also not holding pressure
Nick Hennebury Yes, my stability trac light came on when I first bought my truck about 3 years ago. I replaced the stability trac module that is located up the dashboard up the steering wheel. I don't know if that has anything to do with your truck running bad. You need a fuel pump. But my stability trac light still comes on and goes off for about 5 seconds about every 6 months. I don't pay much attentions to it.
I have the same issue but i replace the pump and still having the long crank issue.any suggestions anyone
That could be your crankshaft positioning sensor. I have a video where I replaced my thanking that was my problem with the long cranking time. But is was not the problem. But it is a little sensor on the bottom side of the engine above the starter. Or do some research on your camshaft positioning sensor. It my have something to do with it. I don’t know much about thing but I replaced mine also. These sensor are like $30 a piece. The camshaft positioning sensor is located on the front of the engine under the water pump. You can see it but you can feel it. I don’t have a video on the that sensor. Mostly likely one of these is your problem.
Replace crank it times the engine on spark and fuel;
Check you charcoal canister it might b full that won't let it vent and it won't start on the first try
Put plumbers tape on it
Did you ever find where the pressure regulator was? I am having the same issue. Thanks BassHunter!
Gene Ray Yes, it was build into the fuel pump. So I had to replace my fuel pump to fix the problem.
That explains why I couldn't find it. Thanks for your help!
Gene Ray I couldn't find mine either! And it's reaking fumes to high heaven. So I guess I'm going to replace the fuel pump.
bigdaddy8896 I had that problem too. After I replaced the fuel pump. About a year later I was smelling gas fumes. And every time I would fill up with gas about a half of gallon with spill out. And I could not figure out where it was spilling from. I had to down my gas tank and the fuel regulator on the top of the fuel pump had popped out of the fuel pump. So I had a half an inch hole on the top of my fuel pump where gas was leaking out. So I had replace the pump again. But the pump was under warranty. So that could be something to think about.
BassHunter thanks bro. I still have the original in with 130,000 on it. When did they start putting the regulator in the pump, late 2003? I have a 2004 Z71.
Sir, why did you even post this video with all of these mishaps?
Stop guessing and changing unnecessary parts that were still good. Confirm issue before wasting your time and your $$$$$$
Was this problem making your service stabilitrak and traction control light come on?
No, just a delay start.
If the stabilitrack message comes on what does that mean?
well what the hell you come up with?
randyusmc it was my fuel pump. It was not have pushing or holding enough pressure to start the truck on the first key turn. It would have to turn over several time to start. So I changed my fuel pump and it fixed that problem.
awesome thanks alot man my yukon I'd doing the same damn thing so I just ordered the ac Delco one. what brand did you get? I was going to try the 70 dollar replacement brand but read they leak.
randyusmc I got the AC Delco also. But I just had to replace that fuel pump again about two weeks ago. The pressure sensor popped out the top of the fuel pump. So it left a dime size hole in top of the pump. Every time I would fill it up. About a gallon of gas would Leak out.
my suburban is doin the same thing did you find out what it was
D-NICE LEE It was my fuel pump. It was not producing enough fuel pressure to start the truck on the first key turn. So I replaced the fuel pump and that fixed my problem. The reason you have to replace the fuel pump is the fuel pressure regulator is build into the fuel pump. Sad I know but that how it is. Thanks for watching.
The BassHunter thanks how much was the pump
D-NICE LEE it was about $200 at RockAuto online.
The BassHunter ok thanks
Do you remember with one you order
I was getting injector malfunction code on cylinder 6 and random misfire code I replaced all plugs, wires, cleaned all injectors and tested injector wires with noid light. I had to replace one injector and cleaned the rest and truck still runs like shit. White smoke and raw fuel. I also keep getting these same issues on the pressure gauge. I'm thinking fuel pump but it's a $300 + pump diy so I'm trying the simplest things first. It runs perfect when front end is jacked up but as soon as I let down on the jack right before my eyes it will huff and puff and jerk and knock and turn on engine light and pour white smoke out the exhaust that is thick and very suffocating. Fuel pressure regulator? Or pump? Any ideas please help!!!!
Jorge Vasquez sorry it has took me this long to get back with but I been fishing. But make problem was my fuel pump. Because me fuel regulator is made into my fuel pump. So you have to change the fuel pump to change the fuel regulator and the fuel filter. All that is made into the fuel pump. Sounds like your fuel regulator to me but I’m now a mechanic.
The BassHunter thank you so much for getting back to me on this. I was wondering if the regulator was a part of the pump because I could not find a single video or anything that showed me otherwise. And as far as the fuel filter being tied into the pump as well...I was thinking that to, but it makes it so much better to hear from someone that has went through it already. Everyone wants to scream compression test when I baby this truck and sometimes she runs fine. Thank you again so much and I appreciate it.
The BassHunter did you ever get thick white smoke from tailpipe that smelled like raw gasoline ? I'm sure it's the pump now because when it's jacked up in the front it runs fine but as soon as I let the jack down it starts bucking and puffing and misfiring .
Jorge Vasquez No, I never got the smoke. Maybe your truck’s computer is try to make up for the lack of fuel pressure and dumping to much gas in to a cylinder or two. But as for you jacking the truck up and it running fine. Is a mystery. I don’t know what that could be.
The BassHunter thank you for helping me troubleshoot. I think the jacking up the truck moves the fuel to the rear and "maybe" the skewer or "sock" that filters the gas or whatever filters inside there had something blocking fuel from getting in ....idk, but I do know ima get at it today and watching videos like yours makes it a heck of a lot easier. Thanks again.
Got to take the tank off sign inside the pump
Bad yukon fuel pressure regulator
Typical gm crack in dash !
Yep 👍🏽
