1997 Express 5.7 Fuel injectors not grounding
ok i've replace all that i could think of but the PCM. The Van has been sitting for 3 years waiting for my father to buy the parts i asked for and he never did. Last week he said go ahead and have it so im wanting to get this thing out of my yard. i replaced the injectors with a used set and still no go. I checked the Crankshaft Sensor and it is getting the 5 volt pulse so now i'm stuck in wondering whats the problem. Thanks for any help lee

thanks for the advice. Today i was able to test out my PCM on a 1997 sierra with the same motor nothing is wrong with my PCM. I've tested each positive wire and ground wire that goes to the PCM and i'm getting 12 volts. The van will start with starting fluid but does after i stop spraying. thanks for any help lee
