1500 model six cylinder 4.3 engine two wheel drive automatic 115,000 miles.
I cannot get this truck to start. When I put gas down the throttle body the truck will start right up and run until the fuel burns off. When the key is turned on the fuel pump does not come on. I pulled the pump and bench tested it and works perfect, good motor speed and pumps plenty. Reinstalled pump after inspecting all connection at tank and up stream wiring.
I then checked the fuses and found nothing there wrong. I replaced the engine bay fuse, fuel pump relay. I hot wired the circuit at the fuse and the pump runs then. Tried to start it and there is no fuel through the injectors. I assume no power to the injectors as well. I have since replaced the ECM, oil pressure switch as well as the ignition module in the distributor. All this and still no success. I am at my wits end! Can anyone help me please?
have the same problem?
