Is the fuel under pressure to the intake? Maybe a restricted fuel filter instead of a pump out? Check all fuses-- inj1, inj2.
When you turn the key on do you hear the pump run for a few seconds? If not check fuel pump relay. If it runs while pouring fuel in the throttle body I do not think you have a PCM problem, or module trigger problem from the distributor, however it is not impossible to loose a PCM injector drive circuit.
Is this a Throttle Body unit or a Muiti-port unit? Any Service engine soon light?
