Hello Sooby World! I have a 83 Subaru GL, EA-81, with an oil pressure gauge. Since I bought the car, the gauge has sat below 0, moving every once and awhile on start up but immediately coming back to rest at nada. Bought a new oil pressure sender (Not the highest quality one, but new nonetheless), and got it installed but still nothing. When I ground out the wire to the dashboard, the dash gauge rises so I suppose that proves my dash gauge works, but when I ran a fresh temporary wire from sender to the plug that goes into the dash, nothing! I was wondering what a proper test of the actual pressure sender would be. I am pretty sure the sender is a bimetal type, and I've read that cannot be tested with a multimeter. Do I need to buy a certain type of sender to work with my dash gauge? Very confused, and not much info in my FSM I got off the web. Any help would be much appreciated.
