Make sure the battery has a full charge and connections all good. I don't know liter size of engine? I looked at info for 4.3L engine, then you have vin z or W. The vin Z should be throttle body fuel injection, you should be able to see fuel injector spray pattern, engine cranking. Fuel pressure, 9--13 psi. The vinW should be port fuel injection, fuel pressure, 55--61 psi, so if about in the middle, should be fine. Engine cranking, do you have spark at the plugs and fuel injector pulse?
