I have the afore mentioned truck. When drilling a hole in the firewall I managed to short two wires together in the wiring harness. (Can find out which two if you would like) Tried a scrap yard ECM w/ proms, tried the new proms in my ECM, my proms in the new ECM... still no check engine light. Got a new ECM and tried the original and scrap proms, still no check engine light. Car was running just fine before this incident. Could a new set of proms fix my problem, or is there anything else anyone can think of? Thank you very much.
