Hello and thanks in advance. I have a 92 c1500 with the 4.3L v6 and a nv3500 trans. I bought the truck cheap as a no start. So far I have replaced the cap, the rotor, the sparkplugs, the ignition control module. I have checked the wires going to the injectors and have the constant 12vdc on one side of each plug. I have continuity back to the ECM on the ground wires for the injectors. The injectors will work if given an auxiliary ground source so I know I've got good injectors and good fuel pressure. It's just that something is not letting the injectors fire I've got 12vdc on the orange wire to the ECM and ground on the black wire to the ecm. The ECM is a 4288 and has the soldered in Cappadocia and prom so I would have to get a complete ECM if that's the issue. Is there anything else I should look at ????
