Chevrolet Classic fuel pump problems

Filed Apr 18, 2017 · Fuel system · MD

My fuel level gauge is malfunctioning. Even though I have had the entire fuel pump assembly replaced and the in dash gauges checked, it will not register past 1/4 tank. After driving approximately 150 miles the gauge will suddenly drop, the low fuel light will come on. After turning the car off and on, it will again read 1/4 tank even when full. The vehicle is almost always in motion when this occurs.

I had taken my son to the dr. And the car had been turned off for less than 10 minutes. When we came back out, the car wouldn't start. It would turn over but wouldn't fire up. After sitting in the blazing sun with my sick child for at least 30 minutes, a friend came to assist us. The fuel pump was kicking on, we cleaned the intake and changed the air filter with no luck. With starter fluid the engine would fire up but died as soon as the fluid burnt off. Before having it towed home we researched it online and found several references to the anti theft system glitch. Sure enough, after leaving the key in the on position for 10 minutes,without trying to start the car, we turned the key to the off position and then tried to start the car. It fired right up. This has happened to me 3 times since then. One time I had to go through those steps 3 times to get the car to start. I am a single mother with 2 children. It is a safety hazard if we get stranded in the extreme heat or cold or cannot utilize the car in case of emergency. Please help me get this issue amended.

The car would not start. The lights on the dash came on, but there was no ignition, no sound of the engine trying to start. I could here the fuel pump start and stop. It was a cool, damp morning. Later that day, the car started with no problem. This happened several times, until we started parking the car in the garage.

Vehicle is a 2005 chevrolet classic in extremely good condition with low mileage for the year. I was teaching my 15yr old daughter how to drive and as we were turning through an intersection the car lost power and died. I had her try to start the car and after the third try it started. The car died again as we were driving home but started on the fourth try. I parked the car and tried to guess what may be wrong. I replaced the fuel filter and had the fuel pump replaced (twice) finally had to take it to a mechanic and paid $766.98 and several hours to diagnose a faulty ignition switch. I would like to be notified if this ignition switch is ever on a recall as this is a very dangerous thing to go out while driving.

The first time I had this issue at the end of last year, I was told I had to have the fuel pump replaced, which was not the issue come to find out. My chevrolet classic 2005 intermittently refused to start. The car would attempt to turn over but refuse. The theft system light would blink during this time. Most recently, the vehicle did this again but allowed my to start it fine for a week and a half but went back into not starting with the theft system light flashing. I thought, how is that, I own this vehicle I am the owner starting the ignition with the key? I have had several mechanics (most recent tires plus, early may 2014) tell me they couldn't find an issue and that without the vehicle currently experiencing the problem, they weren't able to identify the problem. The vehicle finally stopped starting again, so I had it towed to chevrolet this time for service. I was told today that it is the passlock system and needs to be replaced. I have talked to former chevrolet owners who said they had the same issue and kept having the passlock problem fixed every time. They said they finally ditched their chevrolets and got toyotas to avoid the issue. I have also researched a lot of forums, and youtube videos demonstrating this problem which has happened to many other chevrolet and gm owners. I believe that since this has been a faulty part for many owners, then chevrolet and gm should be working to solving this issue for all owners. The cost to repair this issue is high. I believe that since this is an issue that is not uncommon for many chevrolet and gm owners, this should be a problem they should be striving to fix and to reimburse owners who have already fixed chevrolet and gm's mistake. I don't believe there is something we did to cause this problem in our own vehicles, as we aren't attempting to steal them, but simply drive our own vehicles. Thank you.

The vehicles anti theft system turned the fuel off. This has happened 6 times and resulted in multiple towing and mechanics bills. Has also endangered our safety by leaving us stranded along the road. Had replaced fuel pump and filters and lines, etc. Before I determined problem to be security system not allowing car to start. This has been expensive and frustrating and endangered my family.

Anti theft device shuts fuel pump down while you are driving . Then wont restart . Does it repeatedly and ruins fuel pumps.

My 2005 chevy classic stalls and the anti-theft light comes on the dashboard. The car won't start after repeated attempts. Happens at idle or at speed. Very dangerous. Car appears to think it's been stolen. I have found that I can restart after I turn the key off and back on repeatedly. I have now gotten to the point that I can hear the fuel pump come on only after many tries, and then it starts. I've had the ignition replaced and full tune up. The mechanic says that there are no error codes in the computer to research. This is obviously a defect in the design of the car and gm can either recall it or get sued when someone gets hurt. I've been lucky so far to be able to pull over to the side safely, or it occurs while stopped.

Car would not start. Replaced the fuel pump. Not the problem. Found out that the theft system light was the problem after my brother in law called a friend of his that worked at gm. Theft system light comes on while driving and there are times that the car will not start and I have to leave keys in ignition for 10-15 minutes and then come back, turn off and then turn on again, and it starts. This is a common problem with the chevy malibu's. I am fortunate that I have not been driving and my car cut off on me like other malibu owners who are experiencing the whole theft system light coming on. I am taking it to the shop tonight to have the ignition cylinder replaced but have read forums where that didn't help either. Gm /chevy knows that have a problem and aren't during anything about it. Why not investigate before you have fatalities on the road and it comes back to faulty equipment on chevy.
