1997 Chevrolet Cavalier Q&A

1997 Chevrolet Cavalier Question: why won't my car start sometimes after I have driven it for a while.

this problem only happens when it is hot outside, and when it happens when i turn the key, nothing happens, I have power. If I lift the hood up and wait for a while the car will start again. -
Answer 1
Well, it won't start because something is getting overheated and not working. You could replace the battery, starter, ignition switch, relay and the ECM and/or BCM. One of those things listed will most likely fix the problem. But, before you spend a penny on attempting any repairs, you (or someone else) need(s) to diagnose it and figure out which ONE thing is actually bad. Get a test light and Volt/Ohm meter for testing. When this problem happens and you turn the key on, do all the guages and dash lights come on and do the accessories (radio, lights, blower motor, etc.) still work? -

when I turn the key on when this happens everything else still works, just the motor does not turn over. Its like there isn't a motor under the hood, the only sound is the key in the ignition alert dinging. -

Well, get your test light and DVOM and start checking the circuits to and from the ignition switch. Power in, power out, grounds. You can also try swapping the Crank/Start relay with another one in the underhood electrical center and see if it is just a relay. Time to diag. Don't know what else I can tell you. I can provide wiring diagrams if needed. My email is chevyase@aol.com -
