- Today we are checking out a fuel pump replacement for a Chevrolet S10 and S10 Blazer. This also applies to the GMC Jimmy, GMC Sonoma, and Isuzu Hombre. There is a bit of electrical wiring but it is not that scary and I explain every single step there is no guesswork with this video!

all these examples always show a side tank, but the 2003 Blazer has a rear tank, which makes things a little confusing.
This is the best video I have seen as of yet for the wiring. Nice job. It's those little details that are actually big deals.
Wow, thanks!
Yeah, I know...i hate the vids where they just show the b4 and after and the parts but dont show the work, u know, how they did it, the most imp. Part that has U cussing every other word..jaja
Thank you for taking time to make this video....very helpful to me in replacing fuel pump on my '01 Blazer !
You are welcome!
Thank you for making this video. One thing I did that I noticed you didn’t was I put electrical tape over the connectors where the new plug was spliced in. Helps keep moisture out
The plug has a rubber sealer inside it but yeah more protection is even better. Thanks for watching!
Excellent clear video. One thing, those wire connectors were heat shrink connectors. If you heated them, they would have shrunk and sealed around the wire. You can identify them by their translucent color.
Always A True Blue Electrician in the crowd..nice catch...jaja🤣
If agree due to open ended connectors n fluid....
If you need to chisel, try to use a brass chisel if you have one, to avoid spark 💥
I enjoyed the way you presented this video (not dull). Although I'm still trying to find the four corners on that circle.
Thanks for watching!
I just took my 2003 Jimmy blazer to the mechanic to put in a new fuel pump. The hardest part is taking it off. Putting it back on is easy.
Using the fuel pump tool will save you time and energy trust me!
11:31 I was wondering what that mini thing is sticking out south of the fuel sending unit. it has a line connecting to the middle of the fuel sending unit and has a weird cliped line that connects to the lipped and angled spout. I broke mine while replacing and cant find the name of the sub assembly or the part. 2003 chevy blazer ls 2 door. Thanks!
If it is a truck tilt the bed up. So freaking easy.
Man you scared the piss out of me i thought i had the wrong part my 03 blazer has 4 pins then three
Ok i took the pump out but the fuel line connectors I broke the one that goes to the rear. How do I take the nylon tubing off the metal tubing and replace the plastic connector and nylon tubing ??
Where did they find this s10 that’s so clean underneath? Haven’t seen one that wasn’t a block of rust for over a decade now.
The desert. Thanks for watching!
You should have sealed off the wire splices to keep water out of them. Good job.
I got the self sealing ones now! Thanks for watching!
I'am Your Newest Subscriber Great Videos. I Wanta Get My 94 S10 Choptop Pickup Truck Running Again It Hasent Ran In 11 Years 2.2 Liter 5 Speed I Wanta Drive It Again
Thanks for the sub! That's awesome!
Thanks for the great video love how you explained everything in great detail it’s was very easy to follow along in your very great video and I now know how to take my tank off of my Chevy s10 blazer thanks again 😊
You are so welcome!
My pump didn't come with the instructions, would someone mind posting a picture or PDF link of the harness connections?
Mine didn't either. I'm having a lot of trouble matching my wires up. How did you figure it out?
Match the letters from the old connector to the new one... ABCD
Have to access the fuel pump pressure sensor and was debating about dropping tank vs. pulling up bed.. after seeing this video -- dropping the tank appears to be the way that I will go. will comment further after I get this done.
Yeah dropping the tank was no biggie. Thanks for watching Steven!
Took me a month to get to this job on my 2003 GMC Sonoma pickup -- and after having watched this video -- I began the process to lower the fuel tank to gain access my fuel pressure sensor... but the 15 mm nut connecting the front fuel tank strap was rusted solid... and since this is a pickup truck -- I elected to opt for plan B and remove the bed... "Removing the bed" -- really tilting the bed -- worked fantastic for me - There are eight (8) frame to bed bolts.. - fully remove the front 6 bolts; loosen the rearmost 2 bolts about an inch and then tilt the truck bed and insert 10 inch 2x4's in the front "channel" to keep the bed up. This provides excellent access to the sensor and the fuel pump.. - there is another video that I watched that employed this method... but if your vehicle isn't a pickup -- dropping the tank may be the only way.. Another pit of misery moment with this job.... in trying to pry out the pressure sensor -- the plastic stem that sits into the fuel pump; cracked in the fuel pump... but this sensor is designed with a small diameter hole and I inserted a sheet rock screw into the remains of the plastic stem (have to give me brother credit for this fix) and was able to back out the cracked piece... Great video.
My fuel pump isn't getter full power after replacing it nothing is reading correctly and no gas is sending to the engine i already looked at all the fuses and replaced one should i replace the clip for the fuel pump itself?
Did you ever solve this issue?
Man I did what you showed us on the black box and the thing snapped.Better explain it more after
It is safer to use a brass wedge or punch to pound the gas pump ring to move. That way there is no possibility of a spark. You never know and you have gas fumes and gas in the tank;
wow no rust not like hear good job
A desert truck for sure. Thanks for watching!
My mechenic installed three delpi fuel pumps in four months.They all had a faulty check valve.leaking back in the tank.Not leaking in injectors or pressure regular.Or lines.Has anyone else had that problem?What could cause it?
Amazon says this pump assembly does not fit my 1994 ZR2 4.3L.
I wonder if the ZR2 package changes something. Just filter by your truck then. The process is exactly the same. Thanks for watching!
No your Zr2 fuel tank and pump is different from the longer s10 pickup or 4dr Blazer/Jimmy. That's why some pumps may not fit your application.
They use different tanks for the newer S10s, 94-95 and maybe 96 uses a 20 gallon tank that doesn't have the small fuel neck next to the main filler neck. Connectors are different as well and the newer S10s use a 18.5 gallon tank.
Can you change my fuel pump are you located close by on my gmc slt
Not how my 2000 blazer zr2 tank is located
My pump came with a new pig tail and connector. My wire colors on the pigtail are white/black, grey, purple, black.
My harness is Orange/black, grey, purple, black.
No idea which colors splice together.
It should come with literature that tells you which does what. Thanks for watching!
Why some sending units have 2 plugs on top some have just one, this one has 2 plugs
Probably a mid year refresh or maybe the difference between I4 and V6? Thanks for watching!
@@2carpros I found it some units come with gas pressure sensor which is the black plug and some don’t it’s removable so you can just use your old one from the old unit
the 2door blazer has the fuel tank at the back of the unit , but probably the same procedure .
ZR2? Might be only on them. My 04 is a ZR2 and the tank is in the rear
Neither this tank nor pump is ANTHING like that on MY 2 door '93 S10 Blazer (Tahoe LT)!
My tank is at the very rear, and the pump has steel tubing with threaded compression fittings, not plastic tubes or push on fittings. Just fyi..
Nice video
Thanks for watching Carlos!
What would cause gas to leak while refueling after installing?
You might not have put the hose from the body to the tank on quite right. Thanks for watching!
I replaced my fuel pump & a new fuel filter, my truck won’t start, I have a 2000 Chevy blazer 6 cylinder. Any idea why?? The new fuel pump is working
Some with me. I can't get any power reading off any wires going to the pump. And that's when the key is turned forward enough to power the dash
Did you figure it out? Having the same issue I think it’s the lock ring not creating a perfect seal.
Fuel gauge wasn't working my fuel pump went bad replaced it but gauge still doesn't work what could it be
The new sender on the new pump could be bad, or its the gauge itself. Also check for any shorts in the wires from the tank to the dash. Thanks for watching!
How do you remove the center fuel line? Anyone.
I literally went over it in the video. Keep watching. Thanks for watching!
Whats the black box at 3:15?
Charcoal canister for evap system
Don’t forget to depressurize the system! It sucks when fuel is flying everywhere! 😭
Wait, how did you get under there..... ah, that's why I'm taking off the bed
That's a way to do it too. I've just had it on the lift and dropped the tank which you could do with a jack and jack stands too. Thanks for watching!
@@2carpros thanks. Wish I had a lift or level ground which I don't. Gonna have to enjoy the increased mpg's for while lol.
my 04 is completely different , my pumps at rear of the tank.
blazers have the tanks in the back not in the middle like the trucks
@@kazkraynak8667 mines in middle like a truck
2 door?

Ya don't undoo the fuel filler there's no reason
You do realize... you're working on a Gen 2. That's 95 and up. Not a 93.
False. According to GM the production year span is 1993 to 2004 the model year span is 1994-2004. Thanks for watching!
@@2carpros then you explain why my my 5.1994 S10 Blazer is a 1st Gen and the same chassis and parts they used from 91 to 94. They changed grille details and some other very small features from the 80s to the 90 model year. Then in 91 is when they changed. Then, 95 model year, is when they started with the Gen 2 round body.
@@eisernenfuchs123 negative, they changed to the generation 2 in 1994 .The 94, 95 , 96 , and 97 all look the same from the front with the rectangular sealed beam head lights. 98 -2004 they went with the curved or wrap around head lights and a rounded dash.
@@barbiesawada245 I have a March 1994 production line 1st gen. How would I have one, late production, 94 model year, squarebody
@@eisernenfuchs123 if you're truck is a 1st generation square body , it is that , no matter what the sticker says , but according to GMs history on the S10 , production on the Gen 2 started in 1994 , thus the rounder lines , they might have had some leftover 93s they built in 1994 till they started production on the 1994 Gen 2. Remember these trucks go by model year , thus they probably built Gen 1 and Gen 2 in the same year.

worst vid ive ever seen lol
Matches your comment! :D
Have a 1998 Chevy blazer, fuel pump keeps going out, this time we changed the fuel pump and now you can hear the pump powering on and everything but now still not cranking, any suggestions?
Did you check your fuel pressure?
