The oil pressure sending unit is located behind the oil filter, Threaded into an aluminunm housing. It has wiring that plugs into the sending unit. The oil filter has to be removed and you will need a deep well socket and a 6 inch extension. Change the oil and the sending unit together.

ok. oil ight is probably nothing more than a faulty pressure switch.You can have pressure checked at same screw in port. 15psi is ok...just. very cheap to replace. Ign control module is probably the cut-out fault. You cant really test it; repair by substitution is the trick.

Under hood, driver side, front engine area, below cylinder head, where engine meets transaxle housing mounted in block

Take the passenger front wheel off. Look up under the car by the power steering pump, you'll see the sending unit, it's up and back from where the oil filter is. There is a special GM oil sending unit socket, I'm sure you will be able to buy or barrow one from your local parts store! Make sure to have a catch pan under it when you take it out, they can leak a good amount of oil out when you remove it.
