oil pressure
 

I have a 91 k2500 with a 350 5speed and my oil pressure gauge doesnt work. When you turn the switch on the gauge moves a little bit but is stuck way above 60 psi. Is it maybe the gauge,the way the wires are hooked up sensor? It has a motor out of a 89 3/4t. Maybe a wire not hooked up? any help would be appreciated... thanks

sounds like a bad sensor

there is a sensor above the oil filter that i cant find a wire to go to but i hooked the right one up behind the distributor.

is the one above the filter actually in an oil passage or could it be a coolant sensor????? I havent worked on one of the older ones in a while. I will do some looking and get back to you

Im not sure if its an oil sensor or not, it was above the oil filter down in a tube with only one terminal i believe. also my oxygen sensor wire is gone and i wondered where it might come out at up above. any help would be great.
