Correction. Found the oil pressure switch just below the fuel rail. It looks like the wire going to the switch has had a previous repair with a crimped splice. Maybe the splice is bad and the circuit is open. I'll get out there in a bit and ohm things out. I looked at the wiring diagram and it appears that the switch passes a ground to the DME when the oil pressure is ok. Shouldn't I be able to jumper this wire to ground to test the functionality?
