Re: Car turns over but won't start
No Start Problem:
I had the same intermittent no-start problem with my 2002 Chevy Malibu. Could it be the fuel pump relay? I had the problem intermittently until finally, the car had to be towed to the repair shop. The mechanics replaced the fuel pump, then the filter, then a camshaft position sensor, and the fuel pump relay. I had to wonder about the relay. Perhaps, if it had replaced it first... . Total bill was over $1,000. The horn on this car also seemed to have an intermittent problem wherein it did not work. Checked the horns and they were fine. Replaced the horn relay and the problem seems to have gone away. The Chevy dealer said that the horn relay has been replaced by one with a different part number, which I bought and installed. The fuel pump and the horn had the same relay. This made me think that perhaps both had the same problem - the relay. The relay cost me $20 or so and is a lot cheaper what I paid to have the no-start problem fixed. In any event, it would be a good place to start if you have this problem.
I am reminded of another problem, this time on a Ford, that the dealer wanted a $1000 to fix. I took the car back and did some checking that I should have done before taking the car to the dealership and ended up replacing a fuse that cost maybe $0.25. Always a good place to start.
