Fuel pump went out !!!

Cusser · #1 06-01-2009, 11:26 PM

1994 Suburban 1/2 ton, 2WD, Cranking, will start when I sprayed some aerosol starting fluid down the throat. I pounded on the bottom of the fuel tank, then it started up, ran normally. When it didn't start, after cranking 10 seconds then leaving ignition in "on" position, had voltage through the fuel pump relay and fuse, until oil pressure dropped and fuel pump relay clicked off (maybe 15 seconds). So I did that again, leaving in "on" position and went underneath and pounded on the fuel tank again, then heard the fuel pump begin running, until the oil pressure/relay switched it off. Of course right after that it would start right up. So it sure sounds like a fuel pump to me.

Removing the tank with so much fuel in it sounds tough and dangerous to me, too bad GM didn't engineer an access hole. So I think my mechanic gets this job. Anyway, the first fuel pump went 187K miles.

make sure the delphi pump is used,,this is the oem pump,,it appears that this is the period when most of these pumps fail with normal usage...[not running the tank down on fuel]

170,ooo - 200,000mi...

on your vehicle I'm not sure , but I know of dealership tech's cuttting a hole in the floor for access...this is done on other vehicles...

Got it repaired by my mechanic today. $340 total, was a Delphi pump, 2 hours labor, so it was actually less labor $$$ than I expected.

As a dealership tech I would NEVER nor would my dealer allow cutting of an "access hole" to replace the pump on these vehicles.
The tank is simple enough to drop ( even a full 40 gallon tank) that extreme measures like cutting holes is not necessary

well I've worked with dealership repair tech's and on some vehicles this is done....on this vehicle it would be something that,,,, like I said ,,,may not be correct...

since you are a service tech I'm sure that you are aware that some vehicles manufactuered,,,,do have a removable access port for this fuel pump repair/replacement..these manufacturers probably didn't go bankrupt...

No you have worked with HACKs!
And smart @ss, there are many GM vehicles out there that have access holes built in for easy removal of the fuel module.
The Suburban doesn't need one. removal of the tank is simplistic...I can drop a tank on one of those faster then those hacks you worked with can remove carpet, cut holes and patch their work.

your reply reminds me now of the full story of this hole cutting...when a vehicle would come in on warrantee , and it was difficult to remove the tank/tank full they would do the hole cut to shorten the repair time,,, then pocket the extra cash....

Jcat, interesting you live in Everett Ma. I was born and raised in Everett Wa.
Ever been there?

Once again..you worked with HACKS.
Like I said, the tank can be removed the proper way and still I can beat warranty time.
If I caught one of my techs cutting a hole in a vehicle to remove the pump, they would be charged for reairing the hole and the damage they caused, then they would be fired!

It's the handful of HACKS out there ( and yes there are hacks at dealers too) that give the true professional technicians a bad name.

Isn't that like "stealing" ? Even if it was stealing from GM or dealership ?

Was you working at a local junkyard or dealer. I can't believe this goes on at a dealership. They have lifts and a hydraulic jack with a large plate on it to support the gas tank. They don't have to cut holes in the floor.

junk yards dont replace fuel pumps ....dealerships do under warrantee...,,,

on SOME vehicles this is faster....

Some junkyards have a lift and mechanics {parts changers} in my area.
They would install a used pump. Some even have two bays cheaper than a local garage or dealer.
I'm not saying it isn't quicker just a customer who caught this on his new car is going to complain and demand the body shop to replace the piece at least I would.
