intermiting fuel pump

If a fuel pump only is running for a few seconds and then quits . (blows a fuse ) would the car start and run for a few seconds and then die. Is it possible to hot wire the pump to see if it is pumping . If you did this could you run the car that way? ( not forever ) but would it run ?

Re: intermiting fuel pump

Something wrong with the relay that it is not putting out the proper voltage?

Yes you can do that. The pump is grounded through a the pump's modulator under the rear deck. To eliminate all that, you can just find the ground wire at the pump and connect it to ground. The pump will then run at full flow all the time, won't worry anything.
The wires at the pump's connector are blue for power, and a yellow is ground. Ground the yellow wire.
