ED,
I believe the oil pressure light is a separate problem. Here is how I would
proceed to test that theory.  Turn on the ignition but do not start the car.
Unplug the oil pressure sensor. Have someone time how long it takes for the
light to go out. If the duration is the same there is a problem in the
warning circuit.

Good Luck,
Ken
