Hello all and thanks for this forum- you all are gracious for sharing your knowledge on these old 7.3's- Thanks
Now as the title says- I have a problem, @ 3 weeks ago I parked for the nite and the next morning- cranks at @ 250rpm,WTS lite functions, engine oil pressure good. Went to change fuel filter and noticed the fuel heater element was no longer attached to the plate so I pulled the fuel bowl and cleaned it up put back together with reseal kit from Diesel O Rings (removed the heating element but put the plate back in) also all new fuel hoses. Checked the IPR
and it ohmed at 10.5 ohms / supposed to be less than 10 ohms so replaced with motorcraft IPR
from DOR. New one ohms at 0.1 ohms- good/ right? Also replaced the IPR
connector/ soldered the connections and shrink tubing. Cranking fuel pressure is 48 psi
at schrader valve. HPOP
was full ( after sitting for three weeks)
Put everything back together and still no start so I ohmed the GP's/ injectors: GP's ohmed at 0.6 ohms on 5 of them and 2.2, 3.1,12.6 on the other three, need to replace them. GPR checked OK
The injectors ohmed at 2.6-2.9 ohms- so I think they are gtg.
I found oil in the ICP
sensor so changed it with a 'Standard' brand from ORileys/ not Motorcraft. I am wondering if this could be the culprit?
I have checked all fuses under hood, in cab and all are good.
Old girl has @240,000 and has really been trouble free with regular filter changes and general maintenance.
Hope that the collective here can point me in the right direction to solving this.
Sorry for the long post but I am new to diesel's and wasn't sure what to try next? So thanks.
Thought that I should mention I just changed the oil and filter.
