something is activating the relay. Find the power source that is causing it

Obvioulsy you have a short or a direct path to power to the fuel pump. Fuel pumps receive their power from either the relay or the oil pressure sensor/switch assembly on the motor. To start to determine what is wrong, unplug one and then the other to see if that shuts off the pump. If it does, the one that made it quit is defective or there is a wiring problem to the control side of the circuit. If nothing shuts off the pump you will have to trace back through the fuel circuits to find where the circuit is shorted to power. Good luck.

whats up... i might like to help, yet are you able to furnish a sprint extra info? Do you recommend that once you floor it, you in simple terms get 2500 RPMs out of it? if it is the case, initiate basic, then circulate out to the extra progressed. verify the gasoline filters. There might or won't be 2 on that type. A silver one close to the tank, and one closer to the engine. that's close to the driving force's door. If neither of those clean up the difficulty, and you're actual beneficial which you have not crimped a twine while putting the tank back in, then you extremely are becoming distinctive trash on your tank. you may get that wiped clean somewhat quite... yet you will are conscious of it is junk through fact the motor vehicle will run extra acceptable the two idling on your backyard, or whilst moving... not the two. If it is not the case, and the wires (as above stated) at the instant are not crimped and consequently inflicting intermittent grounding, then you extremely are becoming offered the incorrect pump. A low circulate pump that's not for best overall performance autos like GPs. That one is an prolonged shot, yet i've got seen AutoZone, etc. screw up earlier.
