Computer Fried?

The battery hit the frame when I was driving had it towed home now let it sit for a day thought it would reset so I went and connected the ground to the battery and the headlights popped up and kept spinning the motors and the rear defrost seems to be clicking on and off and when I turn the headlights on they flip down and the lights come on and it won't start but all the guages and lights still come on and are ok maybe its a dead battery?

Re: Computer Fried?

The headlight motors and such don't have anything to do with the ECM.

A quick check on the ECM is to:

Key-on, engine-off and observe the SES light. It should briefly turn on, blink off, then turn on solid. If the SES blinks off then the ECM is running. Can repeat the test ofter 10 seconds or more of key-off.
