Did you try the neutral safety switch that activates off the clutch pedal? so you dont start the car in gear? Adam
If the 2000 Cavalier has no lights an will not start, there is an electrical issue. Check the battery, alternator, and the wiring from the battery all the way to the starter to find the problem.
Remove starter and bench test See if you are getting power to starter
I would check the power right at the starter. Either the solenoid on the starter is defective or the connections/ battery are poor.
To fix the cigarette lighter on a Chevy Cavalier, check the fuse first. Next check the wiring and the cigarette lighter itself for a problem.
Defective starter, or a problem with the flywheel. You need to check the starter and then remove it and check the flywheel.
The starter has no control on the spark so that money is wasted. Take it to a garage and have it checked out with the proper machin Check the coil packs
There could be a problem with the power of common ground to the Cavalier light and sun roof. Check the fuses and wiring for the problem.
get your starter check I had same problem it was faulty starter
Have vehicle scanned to determine the problem
A problem with the emission system. Need to have trouble codes checked.
Check the 97 Eclipse starter solenoid. Also check the wiring for any loose connections. Since the battery and starter are goor, these are the two most likely problem spots.
Check the starter solenoid and the starter itself. Either one could be stuck and causing the constant engagement. Check the flywheel for damage after you fix the problem.
