Thank You Brian!! A local shop wanted to charge me $800 to replace fuel pump on my 2005 Chrysler Town and Country, something I could do on my own but lift I had use of was down for a week. It took them 5 days to even look at it and all I was told was they "tinkered" with it. Never put on a lift! I didn't want to spend $800 for a van that cost us $1,500 to buy 2 years ago and had the pump already that cost me only $45. They wouldn't use my part either. So I went over and used the by-pass relay, whacked the tank 3 times and it spun right up! I changed back the relay, got into van, waved goodbye and drove it to the lift I had use of. You Sir saved me $800 and the pounding headache I would have endured from the wife. Love this video and ALL the tricks you do!
Fricken SWEET!!! I LOVE IT ❕❕❕
I didn't want to give you a thumbs up. I wanted to give you a gold star. I have a processing issue with learning. I never understand until I get right into it and do it myself. You having the dissection of the pump and the theory of banging to close the air gap really brought the entire video together for me. And if you think being a 1 man crew can be a little hassle try being a 1 woman crew.
That definitely deserves a Thumbs Up after the educational deconstruction of the fuel pump and analysis! Now that's going the extra mile. Great job and thanks for explaining why banging on the tank works.
Thanks so much mate, I live 20kms from the nearest town about 2hrs from Melbourne Australia and my truck(Ute) wouldn’t start on Friday, and I thought it was the spark plugs, cos I’m no mechanic or mechanical, but after a lot of TH-cam videos and finding the sharper valve, It was/is my fuel pump, I just tapped the fuel tank with a rubber mallet, and magically my Ute started right up, what a relief cos I was looking at having to have it towed to a mechanic, now I can drive it 90mins to my cousin’s place as he is a mechanic and is not going to charge me like a wounded bull. I know I’m long winded 😂. But I just subscribed thank you so much. Hope you stay safe and healthy there in the US. Cheers mate. Jacques
THANK YOU!!! never heard this trick before. Got my truck running again. Just wish that I would have known this yesterday. May have saved myself a good bit of time and money.
I just had this problem at the gas station on my 96 civic hatch crank No start … and i did what you said just hit the gas tank in the middle and First try it turn on and now im back enjoying my day 🙂👍🏾.
Thank you
thanks Brian, you've helped me out with your hacks and tips a couple times over the years and I appreciate learnin from you bro. You're a nation for sure lol.
Not a good video Brian - it's a GREAT video!! I love the way you fix things and then break down/explain the fault and what caused it....Thanks!
Wow, banging on the tank actually works. Wish I'd known about it yesterday...when my truck died 1 mile from my house and I had to spend $125 to have it towed...1 MILE!! SHEESH!
thankz for the informational information with lots of information to inform my brain with,it actually did help me out.you the man
Great video Brian, very cool trick to know.
Hard to find good macGuyvering videos with all these pansies wanting to play by the rules with fear of stepping outside the box. This was helpful.
Love this dude! Such a great sense of humor 🤪
Thanks again Ryan. Love your info. Always good!
My Mazda 121 'Bubble' 1992 (yes 92) ran out of fuel and after putting some fuel in wouldnt start. fuses looked good and it had been 6 years since last fuel pump was replaced. I tried starting it many times. I tapped under the petrol tank in the central area with a hammer (without denting) where the pump would be and then turned the ignition and it started! So far its running smoothly but its only one day ago. I didnt use any wire to bypass any relay.
Worked great for me after hotwiring the fuel pump on a dodge neon. Edit: Wish I had watched this video beforehand, great idea with the jumper relay.
Thanks!
Great info. I wish more/all manufacturers would put the pump removal panel inside vehicles.
Great video, I just part/watched a lot of videos that said that they are going to clean the fuel pump and they only show cleaning the outside of the pump or the strainer, this video helped me understand ,why I need a new fuel pump
I tried this on a Mercedes ML320 and unfortunately it didn't work. But it only takes around an hour to replace the fuel pump anyway.
Excellent video mann!
The top of the pump usually has a check valve as well that keeps fuel primed in the system. This was bad in our Ford Ranger and it would loose pressure the second the key was turned off. We learned how to time it so we could start it again.
Good vid Brian ! Love the trick ..
Ty very much for this!!! Ive always looked into ways of doing Preventative maintenance or servicing things because it helps me learn more on how everything works. I've done on all my appliances and now my vehicle since I own a Ford now. I've recently started to hear a new whinning noise coming from my fuel pump when the AC is on. It stalls at idle sometimes too. Of course its has built in filter, so I'm going give it an ole girrlll scot try and see how it goes 😂 Im a handyman by choice and trade so hoping I don't break any cheap azz plastic pieces that are important, like I've done every other damn time I've worked on this engineered masterpiece
Welcome! Best of luck to you!
Great video !
My Saab 900 is pretty interesting, and by interesting I mean over the top... it has THREE FUEL PUMPS. Two of them are basically fish pond pumps, very slow to move fuel. It has a segmented gas tank, there's a partition in the middle, and the first fuel pump is a fish pond pump that moves fuel to the second half of the tank. The second pump is another slow pump moving the fuel from the second half to a small "bucket" that houses the real fuel pump, and the "bucket" is connected to the fuel rail. Whatever fuel the fuel doesn't use I believe gets dumped back into the first half of the tank to keep the gas even in the two halves. I've been told this is because the tank design used to starve the fuel pump when carving through mountain roads, so rather than change the design of the tank they just added extra fuel pumps LOL.
Sounds about right. It also sounds like it keep the weight of the tanks even too. Most diesel trucks have a similar design, but with on fewer tanks.
thanks my friend you saved me a lot of money and hassle
Welcome!
I have just changed the fuel pump itself, as the owner was not able to afford a whole unit. got him to do most of the work and only had to pull the pump out of the housing and solder the new wires to it ( generic pump) and put it back in the housing. He was doing the messy work with fuel hoses and pulling it out from the back seat. 20 minutes of work and a working GM car again. Old one was at around the 15 year mark, pretty good life.
That's awesome!
You guys are rock my name is shawna I come across your video we couldn't get my 2005 Dodge Durango to start I did everything you said and it started right up by the way I'm a girl and I did it on my own and my fiance was pretty impressed. Thanks again definitely subscribe to your videos.
HECK YA!!! Way to go Shawna!!!! WHOOO HOOOO!!!!
I took my pump apart to clean it was severely clogged. Problem is I didn't see where the spring came from. Idoes it go on the post or....? And thanks for your help. Yes we banged on our tank to get it started. 2002 GMC sierra
Damnit....I've already been banging on it for two weeks. Lol. I thought this was a means to further avoid dealing with the issue. Damn.
BEST VIDEO EVER!!! THX SOOOO MUCH,,my 07 ram 1500 just sputtered for about mile then died,,,if fuse is ok ,,& relay clicks & is ok,,,,,,i may bang tank to start & get it home,,dont want it to get towed,,CAN USE JUMPWIRE ON RELAY IF BAD,,,anyone know cost to replace fuelpump????
You guys are so cute! And intelligent. Great video. Inspiring me to fix my own car.
Great video. I've got to make one of these. :)
Mark that jumper relay with a Sharpie! Thanks for the vid!
good one, thanks...
One thing I've found on the in tank electric fuel pumps is that those people who only keep a minimal amount of gas/fuel in their tanks,and buy their gas at the cheapest place around usually are the ones who need to replace their fuel pumps the most..Probably due to lack of cooling(the fuel is the cooling agent for in tank pumps,as well as the lubricant),and the gas they're putting into their tanks 5 bux at a time usually is not filtered properly which winds up with more water,and trash in their tanks from what I've seen,and determined from cleaning the tanks out...
Shell first and Exxon second. Any other kind of gas will not only mess up your vehicle but, your lawn mower as well.
Awesome video. Thank you so much.
Neil Williams maybe maybe not. In many places the trucks that service the stations get all their gas right out of the same pipe at the fuel rack at the terminal. Here locally from. Montreal they are labeled EXON and OTHER. exon has their own pipeline so want their own gas for whatever reason. ALL THE OTHER stations get generic . That gas goes to all the stations in the region to include Norther US cities. It’s been that way for decades. So there’s no tiger in the tank unless they add it after he gets to the station or the truck depending.
The last I knew even the alcohol in the gasoline until it goes in the truck. The driver puts in whatever quantity for 90% gasoline and adds the quantity to get 10% alcohol that’s about the size of it.
@@neilwilliams8608 it has absolutely nothing to do with brand. It's about what Individual owners do to stretch out there gas in ghetto stores.
Poor people?
@neroaugustus5378 true as some unscrupulous people actually add straight water to their tanks. After all 100 gallons of water in a 3k gallon tank isn't really all that much water per se,but it is an extra 100x the cost per gallon sold which at 3bux a gallon =$300 pure extra profit and no one is the wiser except how their vehicles perform with more h2o per gallon than usual
great video!... you and your buddy remind me of me and mine... feels like I know you... lol, thank for the video!
Thanks and you're welcome buddy!
I just learned some good stuff in 10 minutes thank dude
So Brian using fuel additives does it hurt, or help the fuel pump in any way, extend the life of the pump? Good video as I just had my fuel pump replaced in my v-10.
bad fuel pump....is going to fail any ways...whith or whitout relays...
thanks for sharing!...
@ 13:00 ..... Thanks for the reference to "The Gripping Hand" (and "The Mote in God's Eye") by Larry Nivens and Jerry Pournelle.
+10 for the Larry Niven reference!!
I had my 98 Windstar stall on me. On the side of the road, I took a piece of wire, pulled the fuel pump relay, jumped the circuit making it hot with the key on. I was able to hit the tank and make the pump run. Hit it again and make it stop! I took that pump apart like you did! Great minds take the same stuff apart! Fun stuff!
Another thing that causes fuel pumps to fail is broken wires where they go through the tank. The wire wiggles, work hardens, and breaks. That can cause the fuel pump to work intermittently also. The fuel gauge can also be effective too.
Oh, put some lube on the hinges of that truck!
Thr Bible speaks of people as though they are a nation. It identifies one as a son ss Abraham was the father of many nations.
I could have seen this video before , but I didn't , ran into some trouble and bailed out with a tow truck. Maybe I can get it going, i have a few relays around i may modify to try and get going enough to move it where i can work on it now. What are your thoughts on delphi pumps?
I learn something every time I watch you
I have a problem on my ford fiesta 2001 1.8l diesel, it happened when i hit a huge bump on the road.. before that my engine car run smoothly.. i don't know why, is it my fuel injection pump defected
that modeling picture was hilarious.
My wife's car had a bypass valve go bad, but I just opted to change the whole thing. I didn't want to drop her tank and risk it going bad again in 10,000 miles (her car had 110,000 on it, and that particular pump is known to go anywhere from 100,000-150,000). I thought about just changing the valves, but knowing it's an electric motor with that many miles on it I just couldn't.
Great video and tips you earned a subcriber
Thanks Chris! You're the man! Don't forget to click the bell to get notifications of new videos.
Hit wrong hand definitely a thumbs up. Thanks
i like how you were so focused on the demonstration that you allowed "you're a nation/urine nation" to go completely over your head
Hi on a 95 ford e250 van with the 5.8l engine how do I make a jumper relay with I believe there's 4 or 5 pins coming out and they are sqare shape I'm assuming if I used a test light and find two hot leads to run a piece of wire to each lead and it's basically the same thing right
💡>When it comes to fuel draining out all over your table
I use a doggie pee pad to absorb the spill and it keeps my bench clean
I also use the pad when I clean my guns
02’ Dodge Dakota just died going down the road. Bang bang bang. While the wife turns the key and AAAAAAAAAA (the Fonz) 👍🏻👍🏻 trucks runnin’!
thanks for the teardown
Welcome!
Ok so w the wire from like post to post it looks like your wire form post would cause a like electrical issue bc the little box fuse thing under the plastic appears to be metal and so are you attaching wire to post and pulling it up and over the top of that fuse thing where it apper to be metal (which maybe I don't understand the electrical stuff but metal carries the power right like touching positive cable to metal on car is a problem bc well idk can tou pls help )to post b and wrapping it on the post ? Or are you just jamming something in between the that little thing inder plastic cover w the reddish looking wire wheel thing to make it have connecting
if you can tell me what happened please help me thanks.i got no power to fuel pump relay but ran straight wire to fuel pump car runs and when tighten fuel pump housing down pump cuts off.any ideal what going on car was running fine before this.
So is this the same thing that happens when you drive your car low on gas when it's really cold out? Because I know that can burn out the fuel pump I just don't know in what way.
I have had far more Airtex fuel pump failures than any other brand. 3 or 4 bad ones right out of the box. That have cost me time and money And reputation to have to redo a fuel pump with less than 8,000 miles burn up. Customers pissed, I'm pissed and no body wins, oriellys finally just swapped me out with a Precision brand and have had no issues since. I personally will not use or recommend Airtex to anyone.
Had that happen 12 years ago with Airtex, 2 brand new pumps on same car....NAFTA enabled these pumps to be made in Mexico and China. Went with a Carter, worked fine from that point onwards.
That would be a good place for a brushless motor.
Does this work for Dodge Caravan 96-2000? Is that jumped between 87 and 30 prongs?
Brian, My '99 F150 is doing the same thing and I will try your method. Are there any anomalies that you know of that are particular with a Ford fuel pump that might prevent this from being a good diagnosis? Love your channel!
73challenger5031 Should work, thanks!
I used that dummy relay to get my sister back to the shop without a tow. Problems I have been finding exp with the dodge pumps I'd the fuel control module on R arm has been burning out and courting all kinds of havox with the gas gauge from overheating. It seems to burn first the causes the pump to go. I know oriellys has now gone back to there Lifetime warrantee on the Pricesions pumps after all the Airtex units kept failing.
If you have an Airtex pump keep the tank at least half full or you will burn the sending unit out. My 98 went through 4 Airtek pimps before I switched to the Precision brand and have had no trouble since.
I found out a trick similar to this on my 02 mustang by mistake i found out you can undo wire at fuel pump and reverse them for a quick second and it will go back to working.
So then to truly bring it back to life then you could close the air gap by soldering a nub on top of all the copper contacts on top and test fit it against the brushes and then proceed to file if needed. Your time spent rebuilding one costs nothing. So for those of you looking to save a lot of money I would suggest rebuilding it. If possible. I'm gonna try to on mine. Thanks for posting such informative videos.
Your time spent rebuilding one costs nothing?
I learn something new every video
Great to see you in the comments again!
Awesome video! If I won the lottery I'd buy you your choice of vehicle homie
yes
I needed this video when my fuel pump started going some months ago! Thanks for all your videos, Brian! They were inspiration for me to take apart my car to get at my pump and replace the bugger. Ive driven it about 2000 miles since I replaced the pump including a 14 hour trip (with me holding my breath everytime I got something to eat and prayed it would start up again.) Having your car strand you makes you trust it alot less. But yeah.. its been fine since. Good Stuff!
You're welcome! Way to go!
if you've replaced the pump and you've gone 2000 miles probably go another 200,000 miles before your new replaced pump goes bad.
You did'nt show the part how to empty out the tank with the pump because i would'nt either.
Great video. What causes the paint on the hood to get messed up like that?
Pet Rock's Garage The quality of the paint, and the methods employed when it's applied. In this case the chemistry was bad and the clear coat was applied too late after the base coat. (factory fail).
briansmobile1, interesting. I see a bunch of different cars/trucks with that problem and have always wondered how they got that way. Thanks for the reply.
thanl you for the tip, my pump died yesterday. went under the truck, punch the gaz tank hard. the car start again. it was enough to bring it to the garage. lucky me, it dies right at the garage door. im gonna change that pump
Can you use this kit on scooter
unanswered question can you back blow the fuel line to clear the sock or screen on the fuel pump base
Electrical arcs in fuel, that is a scary sight but fire needs that 1 component more :D
O2!
brushes do not sparks (plasma discharge) because gasoline is a good insulant, not even high voltage can discharge through it.
Definitely no plasma spark!
Inside the cylinder, it's an air mixture with gasoline vapors, so sparks ok 👍🏻
brian we love you
hahaha gracias amigo nice vid
bori lopez De nada amigo. Me alegro de verte!
gracias igual amigo
Banging on the pump doesn't always work. Throw a plastic flex hose on an air gun, clamp it down, send it down as far as you can, turn the key to accessory to power the pump and then blast the system with 100 psi. It'll create a strong enough water hammer to spin the pump free.
fingers crossed!!!
I have an 04 Trailblazer. A few months ago I was picking up my daughter from school. I turned off the car, about 3 minutes later she came out and I tried to start the car and it was literally nothing. I had just filled the gas tank right before driving the mile to her school. AAA tow truck driver said he believes it is the fuel pump completely dead. Is there any way to temporarily make it work just to see if it’s actually the problem? New battery, didn’t respond to jump-at all. And, is that typical? The fuel pump works one day and then they just die and that’s it?
That's how it usually goes.. one day it works until it doesn't.
can i buy one now from you?
I have a warranty on my fuel pump. It kept going out. I banged on it and DOGGONIT it started!!! But why does it keep hapnin???
Hey I have a 02 grand am GT. I installed a new acdelco fuel pump and filter. I hear my new pump running and even took line loose before filter. I'm getting weak pressure and sometimes none. I put 4 gallons of gas from dry empty. Idk if that's enough to prime it or I pinched a hose or could the pump be weak. Idk were to go from here.
That happened to me and I dropped the tank again and the fuel lines were crimped. They were made of something that felt more like plastic than rubber. They crimped really easy from the slightest bend. I zip tied them in place. I think the fuel pressure gives them rigidity but when they are empty they are sensitive to crimping, just like a fireman's hose. This was on a 92 Taurus.
Well it's a year later- a lot has happened since then. How'd it go? For those reading comments- my advice would be to double check the pump install for loose hoses or the pump not sitting in the tank right or a kinked line between the sending unit and leaving the tank.
When you're putting the jumper wire in the relay ...you keep drifting out of the shot! I got to see what you're doing. Thank you for your anticipated cooperation in this small matter. Otherwise it was good information.
The fun dilemma of changing a fuel pump in a truck...drop the tank or pull the bed? Lesser of 2 evils. lol. Nice video.
klc317 Why can't they just make a little trap door in the bed... Oh well.
hey. does this by pass switch stay on and that means my dead fuel pump has been kick sstarted and will keep running???? say yes.
Well until the motor stops on the bald spot again! The next time to switching bang!
If the relay is good, it is sending power to the pump. This "jumper" does nothing different ?????
You could make a tape pull cord to easily remove this "jumper" and to help identity it as such, for future reference.
I enjoy your content. Sir, does my
2005 GMC Yukon XL have a fuel regulator? My
VIN# 1GKEC16Z75J154574 with 240k miles original pump. I can't find one. My fuel pressure reads 50lbs when running. Reads 25lbs with just the Key on but steadily declines to 0. My problem is engine turns over but doesn't crank until the 2nd or 3rd crank attempt. I thank you very much for your help .
“Don’t sue me gosh dang it”
Brian knows his stuff.
Cool. But pretty sure for this truck fuel pump turns on when ignition is ON, no need for the other relay to give it power
It does, but only for a couple seconds. By the time you got to the tank and banged on it, it's power cycle would end. The worst part is that you can't hear or sense when the power stops so you'd bang on in vain. You'd be fine with two people, but with the jumper relay you get as much time as you need to bang on the tank while there's power to it.
Brian have you ever fixed a Chrysler 300M 20004? Mine will not start
curtis smith Ya Curtis, lots of them! It's usually a battery or battery connection if it won't crank, and it's a crank sensor/ cam sensor if it cranks and won't start. Some you can disconnect the cam sensor and they'll start up.
Doesn't just turning the key to the on position engage the fuel pump?
Yes. For every bit of 3 seconds beyond cranking the starter. Then the computer baton for the signal to relay is the duty of the crankshaft position sensor to keep it going.
Good ....but the bottom line is replacing the fuel pump ....competely
You ARE a nation!
Lol!
Leave it to Jafro to know the origin of "You're a nation". It's part of the Dr. Pepper jingle from the 70's and 80's. You substitute "Pepper" with "Nation".
"I'm a [nation], he's a [nation], she's a [nation] you're a [nation]. Wouldn't you like to be a [nation], too. Be a [nation], driiiink [urination]!"
I know. Absolutely horrible. I've got an older brother and sister. I've been called a nation all my life.
***** Way to go Jafro!
Correction: it's top right, bottom left.
The gray one in the middle is definitely a little different .
Nice vid- was that spankys brother :)
Thanks! no
Isnt that just a same thing as leaving a key on for a while to build the pressure back up?
I think the design in cars as if there's no pressure built up in a certain amount of time then power is cut to the relay and will not allow power to continue to go to the pump.
When you're cranking power is continuously going to the fuel pump, and once the car starts when you release the starter motor and snap the key back into its on position, the system senses pressure and if there's pressure it knows the pump is working. When there's no pressure, because the pump was not able to continuously run during ignition sequence during cranking, power to the relay will be cutwhat you release the ignition key back to the on.
I think the relay is designed to fool the system into thinking that you're continuously cranking when you actually are not allowing power to continuously go to the pump and then that's where the bump technique kicks in allows the motor to continue to spend now you have full pressure, start the car so I bought the relays (you need to do that otherwise you'll your battery will train in no time the next time you turn your car off)
but that's kind of the part I don't get when you pull the relay you're just asking for the same issue to happen again once the dark spot reaches the contact point and makes no contact.
@@DanLoFat That's basically it. There's a time - like 3-5 seconds then the computer checks for crank sensor signal and keeps the pixies pump bound long as the sensor says the cranks twisting in the block.
You could wrap a piece of electrical tape inside your makeshift switch to hold it closed
So can I just take apart my fuel pump system and replace the dying pump portion of it and put it back together?
The complete pump assembly is called a "fuel sending unit" and it has the pump at the center bottom of it. Many parts suppliers will offer to sell just the pump so you don't have to buy a whole sending unit.
Nice, they are pricey, I'm going to give it a shot.
@@briansmobile1 play Imma try to get a busy mechanic to swap it out for you or you just got a DIY it
