I was messin around with the wiring under my hood and i think i may have fried the ECU. My dash lights all work and stuff and the car even turns over but it won't start at all. The check engine light is staying on even when i ground out the D4 wire (Check Engine Input) on my P28 ECU. I will check my fuel pump but for now let's assume that it is ok. How can i check and make sure my ECU is ok? I opened her up and there was no visible damage. PLEASE HELP
THANKS!
