there is a fuel pump relay switch under your drivers seat..
the relay is like $8 at oreilly's

hmmm.. wonder if this would be a good time to make a hidden fuel pump kill switch?
has anyone else done this?

Replaced the relay already. The only way i get the pump to shut off is to turn the key off otherwise it just keeps running no matter what.

my fuel pump on my stang is like that too. you click the key on and as soon as the lights the dash lights up,the fuel pump starts going. if your doing any kind of work on the car its a pain cause the fuel pump doesnt stop running, you always gotta shut it off. But my car runs, starts, and drives perfect. correct me if im wrong but don't our cars have a fuel return line that circles everything back to the tank?your car shouldnt be flooding out.

I know it has a return system, but if the pump doesnt quit priming the engine i believe it will flood out. Correct me if im wrong though. Ill try the regulator tomorrow and see what i can figure out cause im on the verge of burning the car down.lol
