no oil pressure

just woke up camaro 355 out of hibernation ,primed engine for oil pressure before start up and gauge does not show any pressure , quick start up fires right up and no pressure on gauge "sounds ok "
was fine when parked in the fall
guessing on trying new sender and gauge first?

Re: no oil pressure

It sounds like you have an electric gauge, can you install a mechanical gauge to first confirm you have oil pressure? What brand/model gauge?

Re: no oil pressure

You could pull off a valve cover and see if the rockers and surrounding areas have oil. This would quickly tell you that the oil is being pumped up the push rod tubes and onto the rockers, indicating oil pressure.

Never argue with an idiot; they'll only drag you down to their level, then beat you with experience.

Re: no oil pressure

I would suspect the sender....or wiring to it or gauge is bad.

FWIW I "T" off the rear oil port and used both OP senders (stock & Autometer) and kept the dash light function .in case one or the other FU.

If you have your stock sender and the wire is still there, swap out the autometer sender to see if the light comes on

you sure no critters got in your wiring during hibernation??

Re: no oil pressure

Sounds like it lost its ground over the winter.

This. If you used an excessive amount of Teflon tape or other thread sealer, the sender may not have been grounded good at its mounting hole in the block.

X2. I actually had to run a ground wire to my sender on my LS.

Re: no oil pressure

ironically instructions with the gauges say to use Teflon tape on sender threads....but to much can "seal off" the ground contact

Re: no oil pressure

I stopped using Teflon tape for these grounded senders, and started using a smear of white pipe dope. I make sure the stuff is inside the threads, and that the threads themselves are shiny, making for a good contact.

When I did use the Teflon, I only wrapped the lower quarter inch; to do this, I cut the half inch tape in half. This allowed for at least two or three of the upper threads of the sensor to be exposed, and to make for a clean contact.
