If the oil pressure switch is not working this could be the problem because the computer will shut down the engine if there is no oil pressure. We should also check for spark in the ignition system.

Here is the location of the oil pressure switch so you can change it out to see if that helps. Check out the images (below). Please let us know what happens.
