Its possibly a bad sender. If you remove the wire from the engine oil pressure sender, see if the light goes out. If so, you either have low oil pressure ir the sender is bad.

The sender most likely is zero ohms to ground with no or very low oil pressure (and sender wire not connected). And a higher resistance when there is good oil pressure. Can check with DVM.
