CHEVY CAR WILL CRANK, BUT WON'T START EVERY TIM
2005 Chevrolet Malibu
July, 6, 2009 AT 6:20 PM
2005 Chevy Malibu 4 cyl Front Wheel Drive Automatic 83000 miles
The car will crank, but won't start every time, and sometimes when it does-- in the middle of driving-- it stops and the steering wheel and breaks lock up: the car looses power.
At first, the anti-theft light came on, so we thought it was the key switch. We replace the key switch cylinder and this didn't fix the problem, but the light does not come on anymore.
We then thought it might be the fuel pump relay. We replaced that AND the fuel filter, and that didn't work.
What could be the problem and what should we get and have repaired to fix it?

Thank you for the donationa and sorry for the delay in replying.
I have checked through the TSB and recalls and did not find any mention of such a problem so it should be something that is isolated.
The first thing to do is to check for trouble codes. Most parts outlets provides the scanning either free or for a nimonal fee. Get it scanned and see if any codes are found.
The next is to test for sparks when engine could not start. This will let us know if it is electrical.
Test injector power supply with a noid light attached to any of the injector wire harness and crank engine. It should blink. This would confirm injector pulsing.
Test the fuel pressure to confirm the fuel pump and regulator are working correctly.
Above need to be verified to diagnose the problem.

Thanks! It was the ignition switch causing problems, so it was electrical. As it appears, many on the Malibu forum have had the same problem! Hope this helps them some.
