After installing a whipple 2.3 kit in my 07 GT I've had several electrical gremlins; 1st a bad (aftermarket) intake air temp sensor, reverted back to MAF and car ran fine. Then a bad MAF sensor, replaced it and car ran fine. Then a bad fuel pressure sensor, replaced it and car ran fine - but for less than an hour. Now I'm getting no codes, car cranks but won't start.
For background, I rerouted part of the engine bay harness and extended one pair of coil and injector wires. I got a couple cross-wired, but figured it out and the car ran fine. But now I'm wondering what else may have been affected.
Any thoughts on what would be causing all this?
I'm thinking of replacing the engine bay harness, just to remove any doubt regarding faulty wires.
