camshaft or crankshaft sensor, or fuel injector circuit problem!
This is from the actron code scanner book.
Have vehicle scanned to determine the problem
Disconnect positive side of battery for at least 5 minutes, worked for my 2002 Pontiac Bonneville. Dealer wanted $50.00 can you say rip-off!
Reset with an OBD2 scan tool, after the repair of whatever triggered the light.
The computer has detected a problem that effects the emissions controls. After having the computer scanned and the problem corrected, they will reset the light. I've had problems with the check engine light on my 98 Bonneville. You have to make sure that the gas cap is put on tightly with a few clicks. If it is loose, that could trigger the 'check engine light' to come on. Hope this helps.
Have you checked the computer codes? If so, what do they say?
if engine will not turn over, check fuses first. then check battery, starter motor, starter motor solenoid and ignition switch
there is a button on the drivers door at the bottom check there
Check under the dashboard, to the left of the steering column.
Salvage yards have books to tell if they interchange. Check with your local yard.
