Average Fuel Pump Life Expectancy ---- What Have Your Experiences Been?

[rocketfast123]

I think my grand am's went out at like 95k. Weird thing is it still sounded fine during prime. During that time the gm dealers had a special where if they did things like water pumps, brakes, and ect. You had a lifetime warranty on it. No questions ask, and you didn't pay for anything..

As for prime. My car can sit overnight and its a key tapper like my olds 307. Other times that bitch will start and forget witch spark plugs is supposed to be firing.

Well, I drove a good 20 miles and then I gunned it to pass a car while going up a steep hill and that's when it died. I think the low fuel and sudden thrust forward sloshed the remaining fuel away from the pump and allowed it to suck up whatever grimy residue was there at the time. It stalled out as if I was out of gas and I' pulled over to a level area where it restarted without issue. Then when I started back up the hill it choked out again and limped just far enough that I was able to safely pull over. Then she died...

Well.... bad news.

At ryans (fisdads) to drop off some cash to him for some of the parts I have sold for him. And I hop in my car to leave... I hear fuel pump prime normal at the beginning then made an unusal groan for the rest of the prime. Start car and it dies. Try to restart and when I try to let pump prime. Not a sound. So sad to say but my stock pump lasted me 203,xxx miles...

Now im stuck staying the night here at his place till we get it fixed. Sigh. I dont mind staying the night. Just wish this didnt happen yet.

[FuriousG]

Wow...what are the odds that we'd be discussing it and then yours would suddenly go out? That's gotta sting a little especially since it looks like yours might have lasted longer than most. I honestly feel bad for you and I'm amazed at the irony of this whole situation. I hope you can get it replaced quickly.

First thing to do is measure voltage at a point as close to the pump as possible, while you attempt to prime the pump.

it wouldn't hurt to check voltage... good idea actually! but i bet with 200k, it's the pump.

nB4 sleepy tries to buy half a pump, or installs upside down.


HEY. replace it with a racetronix or some other bigger better fuel pump and get ready for that turbo build!

I know right, what are the odds... it was a trooper.

Im not even going to try, im positive its the fuel pump. With 203k on it. Its pretty obvious especially that it primed, died then wouldnt prime again.

Actually, thats what im going to do. Im going to call milzy soon. If he has a walboro fuel pump im going to ohio today to get it. Gm/autozone want 200+ for a pump. So might as well upgrade to aftermarket for that price.

.

Yeah, but if there is an open or high resistance in the pump circuit, the new pump won't work, either.

[rocketfast123]

Side note question. Has anybody cut a hole in the in the floor pan, instead of dropping the tank?

So what would cause that?

[plastic_indian]

200k miles of vibration and exposure to moisture, salt, etc. The light trucks in the late 90s/early 00s had frequent failures in and around the harness connector to the pump -- many Delphi service replacement pumps come with a different connector that must be installed to the harness. Blazers were particularly bad about it. It is, however, more than likely the pump in this application. I have never personally found this particular problem on an N car. The relays sometimes fail, however - just swap for the foglight relay to check.

[sleepyalero]

Well good news. Got my walbro pump from MMS today. And modified stock pump assembly to house the walbro pump. Put everything in. Car runs great.

I cant complain. 203k miles on stock pump is awesome.

I sincerely hope that this thread didn't jinx you!

Seriously? Autozone's price is as high as the Stealership? That's surprising!

[AaronGTR]

Yeah, for OEM parts (AC Delco etc) sometimes the auto parts store is just expensive or even more. The generic/aftermarket brands are usually cheaper, but they aren't always available for certain parts, or they aren't always good enough quality that they are desirable.

[sleepyalero]

Yup. Got me a walbro pump for 135 bucks. Did some modification and all good

[pongagt]

The pump on my 99 started to die at 98K while i was driving through Pennsylvania. I made it all the way to my friends in Wisconsin before i changed it. It was very difficult to accelerate but i was able to bump up the speed with the cruise control.

It looks like a access hole for the pump would have to go under the rear seat. I would feel a lot better if i could carry a spare pump around for easy swapping on a trip. Maybe i am just paranoid after having the pump go bad on a trip but i like to keep my car dependable so there is no first time it leaves me stranded. I guess that is a lot to ask from a car that is 15 years old.

[sleepyalero]

Thankfully mine has only left me stranded at friends housesm never on the road. Shes been good to me.

[greddy2race]

219k and still going strong. I did have to replace the fuel sending unit, but the pump is still original..... *knock on wood*

I don't want to turn into sleepy.....

[sleepyalero]

Give it 5 days! It will go out hahaha.
