fuel pump shuting off while engine is running..
How about a little more info on the fuel pump. What brand pump is it? Where is it mounted? It should be mounted in the rear of the car below the tank. You should have a 100 micron filter between the tank and the pump. It can be wired to a toggle switch or wired to the ignition switch. I prefer the ignition switch so it turns on and off with the key. There should be an 30 amp fuse on the +12 volt wire to the pump. Make should you have a good ground to the pump.
