Constantly running Fuel pump?
87 Iroc 305 TPI, the fuel pump continues to run after the ignition is off. It is killing the battery and itself. Anyone ever have this problem? Thanks.

One at a time, unplug the fuel pump relay, and the oil pressure switch and see if the fuel pump stops, if it does, replace the bad part, if it doesn't you probably have a short somewhere.
