Help! Oil Pressure gauge not working in 82 CE

[CDN]

Hello! This is my first post to this forum. I am helping my Dad get his 1982 Collector's Edition Corvette back on the road. We have a nagging issue with the oil pressure gauge not reading pressure. We have replaced the sending unit, the gauge and the printed circuit board without success. All other gauges work correctly including the oil temperature gauge. Assuming the wire harness is not broken, what other components should we investigate?

Thanks

Chuck

Welcome to CAC!!!Chuck.
I'd guess you have broken wire somewhere..
Run a jumper wire from the switch to the gauge,(be sure the gauge/cluster is grounded)
and see if the gauge works

Thanks Bill. I'll try that next time I am in town to work on the car.

Hi Chuck. Although I can't help with your tech issue (and I see Bill has that under control anyway) I just wanted to say hello and welcome you to the Corvette Action Center!

When you have time, post a new thread in the new member's forum - New Member Introductions - and tell us about yourself, your dad and the Collector Edition project you're sharing.

Enjoy the forums!

Isn't the oil pressure gauge also connected to the fuel pump relais?
If so, and your car is still running the problem is somewhere between the gauge and this "fuel pump" connection.
