I have a 1993 chevy s10 with a 2.8L motor in it. The oil pressure sensor blew out of the side of the motor and I replaced it. Now my question is how come when I replaced it and plugged it up up the fuel pump came on even when the ignition was off and the key out of it and didnt turn off until I unplugged the oil pressure sensor. Can someone please help me.
