Customer Question

I have a 00 jeep grand cherokee. I just recently replaces the engine. I checked and double checked everything was hooked properly. My problem is that when go start it no gauges work and the anti theft icon is eliminated but not flashing. When the dealer tryed to connect to computer it couldn't establish a connection. I was told I could be a broken wire but looked over and couldn't locate any. Could be that the computer needs flashing or reset?

Hi, was it the PCM the dealer couldn't communicate with?

If it was, I can give you the pins to check at the PCM to see if it is bad or not.
