Having problems with your 1994 Chevrolet C1500 ?
No s.e.s.lamp no spout voltage to tps map all fuses and fuseable links good .Won't camunicate with scan tool 1994 chevy sub 5.7 tbi 2wd auto trans .Also fuel pump does not come on ,can jumper fuel ,pump ok .My sons friend cut the factory radio out the suburban drove 4 blocks to the store never run again.THank you Jim.
Remove the radio and make sure he did not cut any wires to the ECM engine control (module).The wires run along the back of the radio to behind the glove box to the ECM.If this is all good then check the connections.If all is good then you could have a bad ECM.Tyr the scan tool on another vehicle to make sure the scan tool is working properly.Hope this helps.Good luck.
