Maybe you can install a regular gauge.
If it ever warms up here,-5 tonight and that is not wind chill, I will run a separate ground to the gauge, check for corrosion on the terminal of the sender, and then if all else fails replace the sender, and then the gauge to see if I can get it to work.
No, Mandalay was talking about installing a MECHANICAL GAUGE.
This is done by adding a "TEE" which will allow you put original sender back and have a mechanical gauge connected at the same time..
I have personally had multiple oil pressure senders fail over the years. Each time the sender would give erratic pressure reading from cold to hot..
A mechanical gauge doesn't rely on electric senders, instead it has tubing from the engine directly connected to the gauge and is a direct read of the pressure.
This will eliminate the sender, wiring or even gauge faults.
If pressure stays steady on the mechanical gauge then your engine does not have a fault. The fault would lie in the sender, wire or dash gauge.
If the mechanical gauge does the same as the dash gauge then you do have a fault with the engine and further investigation may be warranted.
