okay so i went to the junkyard and snagged another oil pressure sender, hooked it up and didnt get anything from my gauge. so my question is before i go to buy a brand new one is there a way to test the sending unit? like with a voltmeter?
i would double check with test gauge but i dont have one. im just trying to eliminate things starting with the sending unit, seeings how all my other gauges in my cluster work |

Anybody? I check the wire at my gauge and I have voltage, however when I touch my test lead to the sender unit I get nothing. Does the motor have to be on to show voltage for this? And also now that I know its good at the gauge, guess that leaves just replacing the sending unit or replacing it with an aftermarket. With the price of the replacement sender might as well
 fml.....haha

For the gauge to register anything, yes, of course the engine would need to be on... otherwise it'll sit at zero just as if it were unplugged.
You could try wiring in a 10 Ohm or 25 Ohm rheostat in series with the ground/signal wire for the gauge and see how it responds as you turn the knob.

Have you tried CRE's suggestion of wiring in a rheostat to test the gauge? You can also check the wiring from the sending unit to the gauge using an ohmmeter and checking resistance. Infinite means there's a break somewhere, high resistance could indicate a poor connection, and little to none would mean your wiring is intact and the fault likely lies in the gauge or a defective sending unit.
