87' GT...new fuel pump, new relay, new inertia, new plugs, new wires, new starter, new starter relay...Car is getting plenty fuel and spark...When I go to start it, it fires and then I let go of the key and it dies and wont stay running. If I hold the key over and let the starter turn the motor I can give it gas and rev it up, but as soon as i let go of the key it wont stay running

Does it stay running if you let go of the key but keep your foot on the gas pedal?

Does it sputter out or does it just die? It sounds like you may need a new ignition module.
