Oil Dummy Light Coming On!!

Hey guys, here's the gist of what's happening.

Finished full rebuild of my f22a1 around 4 months ago.
Now, after she warms up to temp, oil light comes on.
No leaks, full of Mobil1 Synthetic, also changed out the the oil sending unit on the back of the block.
Shut the car off, light stays off, then after a few comes back on.
Any advice?

Put an oil pressure gauge on it and see what it reads. How many miles are on the current oil pump?

What was included in "full rebuild"? Did you do it yourself?

I have bought a block with only 500 miles since "rebuild" by a reputable shop(claimed by the seller). I was told this shop is somewhere in Orlando, FL.

I am seeing some sub-standard practice on this "rebuild".

Clearwater, FL is not too far from Orlando.........

I'm just saying,,,,,,,

First of all don't run the engine till you check your oil presure, if the oil pump is gone youll fuck up your bearings.

As cloud wrote use a preasure gauge and check if the preasure is as it should be (at idle and on higher rpms).

If the preasure is good you got a problem with your sensor.

If you don't run the engine, there's no way of knowing what the pressure it is creating.

If you doubt about the accuracy of the pressure switch, you should check the switch on a test bench by pressurizing with regulated air with multimeter hooked up to it. There by protecting the engine.

Cheapest/easiest way for the OP is to replace the existing pressure switch with known/working/new switch and run the engine.

Thanks for the help guys.

When i say we did a full rebuild everything on the car was replaced....except the oil pump. That oil pump is the factory pump with around 270k on it. You guys are saying everything thing I'm thinking. She'll sit here at the house till Tuesday, then go to the shop.
I'm not excited about this problem, I told my mechanic we should replace the oil pump at time of rebuild. You know, when the whole block was stripped and cleaned. He told me we should be fine, ugh!!
