I recently purchased this car it is the SVT. It ran great I noticed a white wire hanging from under the glove box I tried to tuck it under the carpet and when I did it pulled out of the computer. It was a three stage aftermarket chip Diablo brand. The car was running at the time twenty seconds later it turned off. I reinstalled the chip cranks but will not fire. I reset it without the chip same result and the ob2 will not connect to vehicle. Is this a computer problem or a pats problem? Thanks

Hello,

Yep that done sounds good, you could have shorted out the computer. To be sure sure all of the fuses and for a five volt reference from the system, IE any power to any sensor. Here are some wiring diagrams (below) so you can see all of the fuses and a guide to help you test them.

I see an ECM relay as well

Please run some tests and get back to us so we can continue helping you.

Cheers, Ken
