I bought a 2005 Colorado 3.5l with automatic trans. It sat for years and the owner didn’t know what was wrong with it. Right now it will not engage the starter. If I bypass the starter relay the starter will engage and crank the engine. The fuel pump is also not getting any voltage. I haven’t bypassed that relay yet. Is there something common that will affect the starter and fuel pump voltage? I checked the white wire with black stripe on the ignition switch and that does have voltage. Wasn’t sure when the other 4 striped wires should have voltage to check those. With the key turned forward, the passlock light stays lit. Is that normal? I believe the passlock only affect’s the injector voltage. Any suggestions on what to check next? When the key is turned to start, what should I check up to the starter relay and the fuel pump relay?
