[00 cavalier 2.2]

im having similkar problems as leojleblanc.

car will run fine and continue running. but sometimes it wouldnt star back up, and not for hours or days at a time.

ive replaced the fule pump once already and now the new one quick working in only 8 days.

i took the new one out, hooked it direct to a battery and it worked fine. hooked it back up to the car and it wont work.

im getting voltage at the connection to the pump.
but its only 9.6 volts going to the pump while cranking the engine. is that not enough to run the pump?

does anyone know how many volts the pumps needs while priming (first two seconds of ignition in ACC position)

and how many volts the pump needs whiel cranking the engine(trying to start it)?


any help would be greatly appreciated
