my fuel pump is making a really loud whining noise when the car warms up. it doesnt do it when its cold. it also wants to stall sometimes at lights and i have already checked/replaced everything. and started my car up a few minutes ago and it sounded like a damn airplane starting up and then it died. it restarted fine. sometimes the car wil act like it is trying to start but wont but if i give it a little bit of gas it will run but wont idle if i let off the gas but if i hold the rpm's up around 1500 for like ten seconds it will idle but sounds weak. going down the road it drives fine. im stumped somebody please help!!!

 

Sounds like your pump is on its way out.

Usually they wok or don't. Occasionally, and this happened to my last one, It got noisy & worked on & off. I was fortunate to have it working the day the flatbed came to pick up my car, to take it to a shop to get the pump replaced.

 

dammit i cant believe this man i just replaced it about 4 months ago. o well ill take it back to autozone and get my money back and get a ac/delco. is just an original ac/delco a good choice that will last a long time?

 

Mines been doing the same thing from what you have described. I plan to have it checked out soon.

 

Yes, get a good brand name pump, spend the extra money. Bosch or AC delco. otherwise you'll have problems again soon. Also change you fuel filter, and you should do so every other oil change, they are cheap. Most fuel pump failure is caused by restrictions in the filter, especially on thirdgen (or any GM from that era.)

 

yeah if it starts doing it again i will get an ac/delco and replace it. it hasnt done it in 2 days so idk wat the hell is going on but i will replace it if it gets any worse.

 

i had same problem and it turned out to only be the fuel filter just a thought since i had it happen to me.

 

i replaced the filter about 5 months ago when i did the pump but its entirely possible that its dirty and needs to be replaced. thank you guys for all your help it is very much appreciated!!
