1995 Plymouth Voyager 6 cyl Two Wheel Drive Automatic 140 k miles

I just replaced the fuel pump and bled the air out. It
now runs briefly only when idleing, then dies after 10
to 30 seconds, or if I try to accelerate. Please help.

Could be the PCM is not recieving a signal from cam/crankshaft sensors therefore shutting down fuel pump after initial injection. Test or replace cam/crankshaft sensors

AUTO SHUTDOWN (ASD) RELAY & FUEL PUMP RELAY
ASD relay and electric fuel pump relay are energized when ignition is on. These relays are controlled through PCM by switching a common ground circuit on and off. Following components are controlled by ASD and fuel pump relays:
Alternator Field Winding
Electric Fuel Pump
Fuel Injectors
Ignition Coil(s)
HO2S Heating Element
When ignition switch is turned to RUN position, PCM energizes ASD relay and electric fuel pump relay which powers these components. If PCM does not receive a camshaft and crankshaft position sensor signal within one second of engine cranking (start-up), PCM will turn ground circuit off and de-energize ASD relay.
