OIl Pressure

[grindkings]

Alright heres the deal. Got the motor all ready to go. Ecept all my gauges are working execpt the oil pressure gauge. It acts like no power is getting to it. The needle is all the way to the right and even when i turn the truck on, the needle won't jump. Brand new motor. New oil sending unit and yes it is connected. Any help?

Are all your guages running off the same ground ? If not that might be something to check.

Oil pressure and fuel gauge are both 3 wires. +, - and sending unit.

If it doesn't move with the key in "run", then I suspect the wiring or gauge itself.
