Probably the oil pressure sensor (about $55 bucks) and I am willing to bet on it.
The sensor is located behind the air intake manifold and isn't to hard to do, just a little patience.
If you need anything else, let me know.

Grumpy,
The part that I got was not AC Delco, it was GP Sorensen and is called an oil pressure switch. Part #OPS191...
The only other things you will need are a gm fuel line removal tool and a 1 1/16th deep socket. The only other problem was the small vacuum line at the back of the intake that will disconnect when you take out the intake. It is a PITA to reconnect...
Hope this helps...
Jason
P.S.
I did find some great instructions on the forum that showed almost every thing I had to disconnect to get to it... Very good to have...

Oil Pressure sensor, Kinda like the ones in your 412. 
If you can find a disconnect in the harness somewhere accessible you can ohm it out. Probably either open or shorted. Your friendly neighborhood A&Ps can probably help.
