You should have it checked at a repair shop , they will check the pressure with a mechanical gauge ! How many miles do you have on the vehicle ? Could have oil pump or engine bearing issues !
12 psi @ 1200 RPM oil pressure or oil sending unit bad .

When engine is idling the oil pressure sign can come up and that is OK. However if you've noticed that gauge shows much lower oil pressure that a bad sign. Show it to knowledgeable mechanic (but don't be lured in the engine replacement; ask for a root cause - it may be oil receiver or oil pump). Also I hope there's no oil puddles under the car? What about oil level?

As soon as i turn motor on the check gauge light comes on - the oil pressure drops and then the instrument panel said stop motor - it has not been running for a couple years


Check the oil level in the engine. Have the oil pressure checked with a manual gauge hooked directly up to the engine to see if the pressure is good.
