Gas water temp and oil gauge all work on same circuit
Do the other 2 work when gas is not ?

Do you have the ground strap on your gas tank ?

Yes temp works but oil pressure never worked & has ground strap on the sender unit to the fuel line as factory

Fuel sender rheostat at sender assembly could be missing contact between grid and points inside.

BTDT on a replacement unit.

Oil pressure gauge could be gone or sender damaged. Just need to ground the sender wire to check if gauge still works

The fuel gauge starts works all of a sudden then next time you start the car it may or may not work .so grounding it is difficult as it seems to have a mind of it's own

You may need to clean the pipes and grounding strap to have good contact.
