Took battery out had tested, good (only yr. old w/850 CCA).. Lights are bright and do not dim when turning on key to try to start. Checked all fuses, all good. Daughter drove it to work (ran great never had any problems like this before) and 2 hrs. later went to go to break and no start, no turn over, no clicking from starter, but lights radio everything works great with the exception of the lights on floorboard and around cup holders do shut off only while key is in the starting position. They come back on as soon as key is returned to off position. The computer readout checking system on dash says everything, and I mean EVERYTHING is faulty. Damn thing will not even try to turn over. Doesn't even sound like it is even close to trying to sound like it is. After this is fixed I'm gonna find out where that Damn Ding, Ding, Ding and other chime noises it makes is coming from and ripping it out of the car... LOL!!! So with all this said, any ideas what it might be??
First thing I would probably check is the voltage at the starter solenoid itself when someone is turning the key. No voltage it could be the relay. If voltage present then the solenoid is the issue.
Change the main computer. Not everything can go wrong at once. But when car computer goes wrong it sends wrong meesages.
