Had the same issue. Replace sending unit and all is fine now.

Well I started it up this morning and it went up to like 60psi at idle. Thinking that if there were an issue internally bad enough to create 0 on the gauge it wouldn't read 60. Gonna see if Jerry has a new sensor...

Sounds like it could be the sender. And, then again, the dash instrument cluster board contacts have been known to get "frosty" (read: oxidized), requiring some cleaning and some contact cleaner spray.

I agree w/ others on the sender, and I'd begin with the sender. It is easy to replace, and more likely the culprit, from my experience with senders (in general), especially with a car that has sat for extended periods (as I'd guess yours has seen some extended periods with little running).

Might add.....that electrical connector plug on gauge oil pressure sending unit is finicky sometimes and checking/wiggling the electrical plug on top of the oil pressure sender may solve incorrect dash oil pressure readings.

I'm out right now, presently sourcing in AC-Delco for stock.

In the meantime, try this for a source local to you.

Cool - thanks guys! I will clean the contacts and see what happens. Then I will see about getting one. Nice to know that it isn't an internal engine problem....

UPDATE: I ordered the sending unit from Jerry's, replaced yesterday. Seems to read MUCH better now. It is a 5 minute fix just to let those who may have oil gauge problems know.
