Hello I have a 2001 chevy cavalier and yesterday morning I tried to start my car and turned over the key and it did absolutely nothing. There was no clicking or winding noises only noise I heard was my fuel pump kicking on. All my lights are working normal and so is my radio. I tried jumping it just to make sure it wasn't an issue with my battery but it still wouldn't start. What could be the problem? 9 Answers

I have a 1989 Camaro RS V6. On my way home from work yesterday I noticed that all my guages are floating the speedometer was bouncing around between 60 and 70 sporadically. The temperature gauge, oil gauge, rpm and gas gauge were all floating around when I slow down they all start coming back down? For just a second I smelt a very strong burning smell (electrical) that very quickly faded. The SES light has been on constant the whole time this is happening. Same thing was happening on the way to work this morning car is running and driving just fine. I guess today when I get home I can check the codes to see what codes I get as a starting point and work my way from there. I will also check the ground wires to see if maybe I am not getting good connection somewhere. Could it be my battery by chance? Maybe even a stripped wire somewhere?Any help would be greatly appreciated. Thanks! 4 Answers
