The fuel pump fuse is in the fuse box under the back seat next to the battery. Fuse #6 is for the fuel pump.

Expert:  Marty replied 1 year ago.

The pump is under the car at the left rear. I've attached a picture.

There is a plastic cover over the pump that you will need to remove.

OK found it here's deal I have to keep hitting it to keep running it will run stop I hit it it runs second stops over n over
Expert:  Marty replied 1 year ago.

Are you hitting the fuel pump?

Customer: replied 1 year ago.
Expert:  Marty replied 1 year ago.

Well assuming that there is 12 volts to the pump at all times when you are cranking the motor it would indicate a bad fuel pump.

Customer: replied 1 year ago.
Wat if it is not
Expert:  Marty replied 1 year ago.

Possibly a bad relay. You need to measure the voltage to the pump when cranking the motor.

Expert:  Marty replied 1 year ago.

The fuel pump relay is next to the fuse box under the seat. I've attached a picture below.

Ok, are you going to replace the pump and filter?

I think filter was so clogged the pump was shutting off because of ptessure
Customer: replied 1 year ago.
Is it the pump or the filter that keep fu el from draining bac when not running
Expert:  Marty replied 1 year ago.

It's both. The pump and the filter both have check valves in them.
