Truck was working fine, before this mishap. While working on my 1994 OBS Powerstroke, 7.3L, with a screwdriver, I accidentally touched a power source with the IPR Solenoid housing, causing arcing and a black spot on the IPR Solenoid. After this, truck would not start. FORScan diagnostic testing through the OBDII connector revealed a problem in the IPR circuit. By the way, the IPR valve is very new, the HPOP pump is very new, the ICP sensor is very new, and I've verified oil is pumping through the HPOP rails while cranking, but now builds zero pressure (I have a physical pressure guage on the HPOP rails). I check the power/ground leads to the solenoid on the harness (also checked for Oms) and got ZERO volts KOEO on both pins, and I also got an OPEN circuit results for Ohms on both pins comming from the harness. I swapped out the Solenoid with another one I had, and still no start. I swapped out the PCM relay with the horn relay, and still wouldn't start. I checked all fuses inside the cabin and under the hood in the 2 fuse boxes, and all fuses were in tact. Assuming the wiring harness is ok, what are my MOST PROBABLE solutions? Swap out PCM?
