When the engine is cranking, is there an injector pulse?
I believe under a certain rpm the ignition module controls the spark. It is possible for the ignition module to see a signal and the computer doesn't. If the computer doesn't see an rpm signal, the injectors won't pulse.
There should be a purple wire with a white tracer going from the ignition module to the computer, with the engine cranking, there should be a signal on that wire. No signal and the injectors won't pulse.
There should be an oil pressure switch in the fuel pump circuit. Even if the relay is faulty, once you crank it enough to build oil pressure, the pump should run. You should have fuel pressure?
