"...diagnostic bypass jumper for the MAF..."? (I think you meant AFM-air flow meter but that's just semantics.) What jumper? Do you mean jumpering the fuel pump terminal in the diagnostic connector to activate the pump? Also, (and you probably know this) you have to have the duct from the throttle body to the AFM connected or it will not turn the fuel pump on.
The code gives you a good idea of what's wrong: the ECU is not getting the signal from the distributor signalling the engine is turning. The ignitor is aware the engine is rotating which is why it will run with starting fluid, but the signal is not being passed to the ECU for some reason. The ECU will not fire the injectors if it doesn't receive that signal and this is why the engine dies after a couple seconds. The cold start injector is supplying enough fuel for the engine to start and the ignitor is firing the plugs. But since the ECU doesn't get the NE signal the injectors are not triggered because the ECU cannot determine the engine rpms, how much fuel to inject and when to fire them.
