was this the problem why you changed the fuel pump?yell me all you can about the van........when it wont start,does it have a spark on the plug wires?will it start with starting fluid when it acts up?
you need to check the fuel presure,even though you installed a new pump...it is common to get a bad new fuel pump....these must have no less then 58psi at all times....

CIRCUIT DESCRIPTION When you turn ON the ignition, the vehicle control module Vehicle Control Module (VCM) energizes the fuel pump relay which powers the fuel pump ON. The pump remains ON as long as the engine is cranking or running and the VCM receives reference pulses. If there are no reference pulses, the VCM shuts the fuel pump OFF within 2 seconds after the ignition was switched to the ON position or if the engine stops. The VCM also turns ON the fuel pump for 2 seconds when you turn OFF the ignition.An electric fuel pump pumps the fuel through an in-line filter to the fuel meter body assembly. The pump attaches to the fuel level sender assembly inside of the fuel tank. The fuel pump provides fuel pressure above what is needed by the fuel injectors. The pressure regulator keeps the fuel available to the injectors at a regulated pressure. Unused fuel returns to the fuel tank by the fuel return pipe.
great glad you got it going
