Pontiac Sunfire fuel pump problems

Filed Jun 16, 2020 · Brakes, Fuel system · 160,000 miles · SC

My car was driving perfect until 3 weeks ago, it has since then wont start back up. Thought it was something to do with spark, then tried spark plug wires, new battery, checked alternator and fuses, coils all good. Then I was lead to maybe the gas that was in it. Dropped gas tank, put new fuel filter, checked fuel pump, gas lines, it did stay running one time since but was shaking roughly with a flashing check engine light. Will not run anymore since then. Have not been able to drive my vehicle for 3 weeks now and it is my only car.. Also before the car started having the above problems my brakes kept getting tons of air also losing a ton of brake fluid, ABS light stays on and all brake lines are good. It's dangerous. Also have bled the brakes. Not much help other than temporarily.

Sunfire won't start a something with fuel pump

1998 pontiac sunfire gt anti-theft system won't disengage, car is dead. (when the anti-theft system is triggered, the fuel pump is shut off) it may have been triggered by using a copy of the original key. Following manufacturer's instructions (turn on iignition for 10 min, turn off and turn on again) doesn't work. An internet search revealed that there are 1000s of people with the same problem with sunfire and other gm cars. I would like gm to acknowledge the problem and repair the faulty system.

I too have a 2001 pontiac sunfire se 2.2 auto with about 58,000 miles on it. I bought this car in march of 2002 with only 14,937 miles on it. I had no problems with this car till november 2004 at 44,874 miles, when an 8 point buck ran into the left side front fender and damaged it, the hood, windshield, driver's door, roof, and back door while I was driving 55 MPH. The car was repaired, then sat outside for about 4 1/2 years. Had to install a new fuel pump and battery, then I started driving it again every day in november 2009. Now I have no high beam headlights, lights are good. Also, when I put the transmission into gear, the daytime running lights flash real fast about 7 or 8 times, then go out, and the service light comes on, but if I turn on the low beam headlights first, it is fine! Service light goes out after car is turned off and restarted, until put back into gear with the headlights off! I have replaced the daytime running lights relay with a new one, but it still does the same thing, and if I leave the relay out, then when I turn on the headlights, one is normal and the other is real dim!! This has been an ongoing problem for about a year now. I thought it may be a problem stemming from the deer damage and repairs, but I see from all of the other comments on here from the past 9 or 10 years or so, that this seems to be a common problem with this car. Would this be the turn signal/dimmer switch in the steering column causing all of these problems?? Any ideas?? Thank you!!

I purchased the car in october 2003 and the car was great. In march 2006 I started having problems where the car when attempted to start would take a few seconds extra and then start, then 6 months later I was driving down the street and the car just cut off in the middle of an intersection. The car restarted about 10 minutes later. Then in november this started happening more an more frequently. One night in december the car cut off and would not restart at all. I was able to pull of the road. I waited an hour and still the car would not start. I came back the next day and the car would not start. I got the car towed to a mechanic who said that he thought it was the fuel pump so I replaced that and the car worked for 2 days and then the same problem again. He then tested the car and saw there was no power going to the fuel pump. I had him do a temporary fix and run a line from the battery to the fuel pump so the car would still start. Then everything else slowly started to fail. The air bag light would come on intermittently and now stays on. One low beam headlight went out and then the other followed by my high beam totally. My front left turn signal went then the rear right followed by the front right. My horn no longer works. I don't know if my airbags would deploy if I was in an accident. The windshield wiper recently stopped working as well.

I had the fuel pump replaced on this vehicle in december 2006. I have been given information indicating this pump is in the suspect group of pumps covered by the delphi recall number 07e-015. I contacted the number listed, and was told that since someone else had entered information on the VIN that they will not tell me anything. They refused to tell me how to have the inspection or reimbursement done. This vehicle was wrecked by my daughter in march 2006, and there is an ongoing investigation of the ABS system also.

When slowing down to a stop, or turning the car loses complete power. No dash signs are shown during this process. Starts up immediately if heat/defrost is not turned on or is turned off, let the car sit for a minute. This happens when defrost or heat is used or not used only happens in the winter when temp. Falls below 40 degrees. Every time I turn on the car. In the summer and spring if it rains the car loses power when there is any amount of water on the road, does not have to be standing water on the road new fuel pump, steering cylinder,clutch has been cleaned several times, battery and alternator have been replaced, hooked up to all electrical machines at several dealers and nothing shows a defect this has been happening for 2 years after the car hit 60,000 miles.
