The problem I'm having is that the fuel pump is wired directly; I mean, when I turn the ignition switch on, the pump starts and doesn't turn off. I'd like to know the wiring diagram for this pump, how it's connected to the relay, and how I can fix this problem. Thank you very much.

What do u mean directly?? if the engine dosnt flood with gas, my guess wuld be fuel pressure regulator just returning the gas in the gastank
