Yesterday
changed the OPS and now have power from it,but no ground at lift pump still.
I think the actual OPS should have been grounded to get proper gauge operation while it was on my test rig.
Brought up to operating temp.Unplugged the temp sensor while at operating temp and the engine changes RPM and sound,so that appears to be working.
Will restart warm without glow plugs or lift pump within a few minutes of shutdown
Wait 15 minutes and nothing.I can feel and hear the shutoff solenoid when at operating temp when i have the switch cycled or if the switch is on and i unplug it.
Head scratcher...
Is there any other electrical component that could heat soak while the ignition switch is off that would interrupt the IP function?
Thanks Again
