My Electric oil pressure gauge seens like it is stuck around 20 PSI. The GND is good, and the Ignition wire is good(i think), so I have it narrowed down to the sender. Nothing seems wrong with the sender wire, so what could it be? I bought the gauge brand new, so I doubt its the actual sender. When my key is in the position before start, the gauge gets power and stays at 20PSI. When the car is started and running it also stays at 20PSI.....I am out of ideas.

*EDIT: Problem solved; This was the problem; Teflon tape was blocking the oil hole for the sender. I remove the excess tape and a blob of oil came out. Now the gauge works

does it have any other devices on the power/ground line that may run static to give it a false reading?

with only the ign on my guages reads below the number and at idle my oil pressures is just about 50psi.

check your power line it should not be getting a reading with only the ign on cause there is no pressure from the oil pump, since the crank is not rotating
