Could be I've had all kinds of problems with that being the root of them hell I've had tranny problems because of them

 

[98_k1500]

The ground wire that breaks out of the wiring harness at the back of the engine (i assume its a ground anyway, It was a ground on my other truck) was broken. (the one that bolts on the back of the passenger side head) I soldered a eye back on the end of it and grounded it like my other truck was, EVERYTHING else on the truck works, so i assume this is correct.

That is correct if all your ground are hooked and properly grounding I would assume that your wires to the sensor have a short or pinched somewhere if not the sending unit is defective

I really need to know what a working gauge does if you unplug the sending unit and turn the key on. That would help more than anything in pinpointing the problem.

Mine being a 94 model if don't think I could be much help but here's a pic of my gauges with the power cut to all of them

You must be registered for see images attach

Keep in mind this cluster for sure is a good one

 

[98_k1500]

yea, i know my cluster is good. already tested it. I need a truck like mine, the sending unit unplugged, and the key turned on to see if the oil pressure gauge pegs or if it just sits there.

I can get you the info tommorow for sure my buddy has a 97 gmc in the alignment shop

 

[98_k1500]

it would be appreciated. no hurry, it runs fine and i know its got oil pressure. It would just be nice to know if i blew a oil cooler line or something.

 

[Hood93z]
