Story behind truck – I bought it as a crank no start and got it to this point. IDM was fried, injectors blown out. 2000 Ford Excursion 7.3 4x2 with 276K miles.
Rough start, dead passenger bank. Manifold is cold.
FFD Stage 1 injectors installed.
No codes in PCM or IDM, injectors all pass buzz test. All Injectors squirting oil from deflector when running. No visible high-volume leaks. LPOP reservoir filled to top.
IDM Harness Ohm’d out to all injectors and GP at 2.9 Ohm. IDM is new unit from DTC.
Main harness removed multiple times and continuity, and OHM checked, all pass.
Both driver and passenger UVCH changed. Connectors verified on both sides.
Driver VC checked for abrasions on wiring, none found, put heater hose on the wires anyway.
Checked Oil pressure at rails, >2000 idling on both sides with high pressure mechanical gauge.
Fuel filter showing 60 PSI pre.
Removed passenger check valve, was a little sticky so removed it. Blew out line towards the filter to verify its good.
No fuel in coolant, No Fuel in Oil, fluid levels remain the same for both.
I also swapped in a known good IPR, same ‘no fire on passenger’ condition.
When valve covers were on, I did the flip the oil cap upside down and it just vibrated, not a lot of pressure.
I don’t know where to go from here. Any help is appreciated.
I have used search, watched videos, etc. But here I am.
Thank you, Joe
