Okay I had a post a couple days ago about not getting any power to the fuel pump. Well I believe its a wiring issue because when I mess with the wires on to of the fues pump it starts working, car is started and runs great. Well when I shut if off the pump keeps pumping and runs doen the battery overnight. Of course I did'nt get this figured out until the next morning when the car was dead. I put it all back together and when I turned off the car I heard this sound like a fan coming from the motor so I didnt think to much about it. Turns out the pump was trying to push gas to the motor and that was the sound and my batttery was barely charged. Any Ideas on what to do? Please help!!!

You probably have a short somewhere, Get the FSM and start testing wires.
