howdy all. My diesel hpx 4x4 died suddenly. It will run but only while the key is in the start position I have narrowed it down to a lack of power on the hold (red) side of the stop solenoid. I switched out the ignition module with a known working unit and that was not the culprit. I bench tested the relay and it appears to be working. I bench tested the stop solenoid and it works as well. I do get the oil pressure light as well but don’t know how to test oil pressure switch. I guess I’m just looking for suggestions on what to Test next and how to do it.
Many thanks.
