Connected Battery backwards...ouch!

oil preshure switch word doesn,t make sense to me.The oil preshure sending unit is for the gauge or light only.it has nothing to do with the fuel pump or motor running. it just tells you when you don,t have oil preshure.a good place to power the fuel pump relay if you have one is the dark blue wire that goes to the electric choke and ignition.Do not run the pump directly from it with out a relay in between or run it from a seperat switch.I persanally don,t like ad on electric fuel pumps for moderate hp motors.They don,t no when to stop pumping and are a grate way to burn a car to the ground.
