2003 Chevrolet Impala: fuel pump failure

Filed Sep 16, 2019 · Electrical, Fuel system · 47,000 miles · TX

2003 chevrolet impala 3.4l is difficult to start, replaced many parts to try and fix: fuel filter, fuel pump, spark plugs and wires, oxygen sensors, fuel evap valve, and throttle control. Vehicle currently has 52,xxx miles. Security light flashes, was able to pull error code p1626: theft deterrent fuel enable signal not received. Keys are original to car, I have tried to re-learn keys to vehicle with no success. Numerous repairs are listed under this error code, including the replacement of the bcm, and this doesn't always fix the problem. This issue needs to be researched further.

On a cold start my car will not start for at least one time, and once you get it on the highway the car will surge and jump rpms and occasionally will just die and leave me stranded on the highway. I've replaced just about every sensor relating to the issue and the fuel pump and still have no idea what is wrong. I still owe money on the car and I'd rather just figure out how to fix it. Thank you and I look forward to hearing back from you.

Under the hood fire and unintended key rotation. Maybe 5 days after I took my vehicle into tc chevy (in ashland oregon) to have the 2 recalls repaired on it. I tried to start my car and it caught on fire down by the front bumper and the flames made it to the back side of the motor and ignited the fuel lines causing a mini explosion under the hood, mean while I'm sitting in the driver's seat. I jumped out of the car nearly having the life scared out of me, I popped the hood and grabbed my house garden house and started to try and put the fire out and minimize the damage to my vehicle while I waited for the fire department to reach my house. The fire department showed up and was able to get the fire put out almost torching one of the firefighters head when the fuel pump kicked on without the keys in the ignition and started shooting gasoline reigniting the fire. I'm lucky the fire didn't burn down my house and my neighbor's house that day seeing how the fire caught the bush next door on fire and there was flames 14 ft in the air. See chevy and gm have been trying to act like the fire and the damage to the vehicle is my own fault and none of their own even though the technician says none of the repairs were actually done. I've been trying to get an investigation done and they're trying to push my claim aside and sweep it under the rug. My vehicle was parked in my driveway at my home right next to a bush not my neighbor's house is right up against. Please look into this so that it doesn't get swept under the rug. Please help me. I also have the firefighters report.

I first started having this problem in october 2015. I purchased this vehicle in july 2015. I trusted this company because I seen they had great reviews. I actually trader my previous car in because it was having problems starting and also shutting off while driving. Now my current car is having probelms starting. I had my battery, alternator & starter checked, and it was good. The company I bought the car from provided warranty coverage on the vehicle. I took the car to get serviced in the beginning of october for an engine mount replacement. They replaced my engine mounts and fuel pump. 2 days after that service I started having issues starting the car. When you put the key in you usually hear beeping noise and I didn't. Than my battery light, ABS light, trac off light came on and stayed on and in the message center tracking system light came up. This was very inconvenient due to the weather and having to get 2 toddlers ready for school in the am. I took the car to my mechanic and he replaced the ignition switch. I didn't take it back to the same place because everytime you take it for service my deductible is $100. After 2 weeks after replacing the ignition switch the problem happened again. So I called my warranty service center they said to bring it back but if it needs fixing I have to pay again. (also I am paying a car note of $115 a week). I refuse to keep paying money for this problem. This can be very dangerous in so many ways. It's very fustrating because I trader my previous car (2000 buick regal) in for the same reason. I'm not sure if it's a wiring issue, sensor issue or maybe when they changed my engine mounts or fuel pump something got disconnected. This problem didn't start until they did service on my vehicle. Please I need some help on what to do. Little minor issues I don't mind keeping up with but something like this needs to be fixed!

Several times since I got my car, it has stopped running while I was driving. I had the mass air flow sensor replaced, the fuel pump, the bcm also but it still continues to shut off completely while I'm on the road. My check engine light was not on the last time it did it and I've done several repairs to attempt to fix it. Ive spent nearly 1000 in these repairs and still nothing works. I'm afraid to drive my car but I have to work. I take care of my vehicles and I'm not sure if this is a gm issue or what, but I've read many complaints sounding similar to mine and I want something done. I was on a very busy road on these days and in complete motion (35 MPH and above)

Tl*the contact owns a 2003 chevrolet impala. While driving at various speeds, the vehicle would stall. The dealer made repairs to the catalytic converter, however following repairs the vehicle experienced the same failure. The vehicle was taken to an independent mechanic where the mass air flow sensor was replaced. The repair did not correct the failure. The vehicle was taken to another dealer and the catalytic convertor was repaired a second time. The dealer also advised replacing the sensor but the contact had recently had the sensor replaced. The vehicle continued to stall. The vehicle was taken to a second independent mechanic where the fuel pump was replaced but still, did not correct the failure. The vehicle was left in the possession of the dealer where repairs were made to the electrical system. The failure mileage was 61,500.

I have a 2003 chevy impala and the security light keeps going on when I drive or a few minutes after sometimes it wont start too. Has new fuel pump,filter,complete tune up, everything is up to date on my car but the security light will still come on. I have heard plenty of complains and they all lead down to the " passlock system" so far no one can figure it out. They said the ignitions wire must be soldered directly to the passlock sensor? But I don't really know.

My 2003 chevy impala has the passlock security system and out the blue my car will not start. This has occurred 3 times in the past 3 months. The 1st time it started right up at the dealer but they said the fuel pump was bad. The second time was on fathers day and I waited 10 minutes and it started up. Took it back to the dealer but they just said without a code they can't do anything. Third time I again waited 10 minutes and it started. I just know some day that trick is not going to work. Why can't gm admit there is a problem and correct this problem. Its all over the internet and people are spending tons of money on fixes that don't solve the problem.

The car was bought new from dealership, with occasional grinding noises noted in reverse and headlights "surging" at night while driving. Dealership unable to replicate with the exception of grinding. I was told a loose wire was causing noise in reverse. On 09/26/05, after noticing hard stalls while attempting to start, the fuel pump went out $281.60 for new one. 12/09/05, to dealership for starting concerns and maintenance. 04/13/06-car would not start to leave work. Ward's chevrolet came to my work site. Left me a rental and kept my car until 04/20/06. I paid $674.56 for a 2nd fuel pump and fuel module. 06/21/06- to local garage with same complaints. $100 paid for "short" in electrical that caused no start and towing. 08/04/06-cooper buick in monroe,la- $281.00 for another fuel pump and recall on 2003 impala headgaskets that I was unaware of. 11/22/06-no start, turn over-went outside 3 hours later-starts with hard start. 12/06/06-brakes went from quiet to grinding-slow hard starts continue. Ward's kept the car for a month-never told me what was wrong with car except brakes. Did not charge. At this time I had requested a gm investi.-no results-states"the dealership was unable to replicate concern". The car continues to have slow, hard starts with very noticeable gas smells. The smell of gas has been occurring since 04/20/06 repairs. Now service, ABS, security lights come on and off intermittently with the smell of gas and slow, hard starts. I have been calling ward's since the first week of march 2007 requesting factory rep. To meet and drive car after their having a month with no improvements in cars functioning. I called this a.m. To be informed that new service dept. Manager was not aware of problem. This is the 4th time since march I have requested the factory rep. With no response from ward's.
