Here is what happened.. I parked the car for a year, and when i got back, rats had eaten the wiring under the hood.. i had Chandler electric rebuild the harness.. I reinstalled the harness, and everything works, but im not getting engine controls from the ecm.. No fuel pump, no spark, i tried doing a diagnostic mode on the acdl link under the dash.. but the engine light never blinked. Im about to pull my hair out. Any advice would be really great.

Oh, its got the 5.7 L tpi motor.. with a hypertech chip.. i checked for power at the coil, and there was none..

 

Have you got 12V power to the ECM - both the switched power and the constant power for the memory? Have you got a good ground for the ECM?
