Now I know squat about these electronic diesels, but is it possible this all could have triggered a limp mode, or safety precaution set into the puter that can all be reset by simply disconnecting the batt. cables for a minute?
I know from experience that the 99 up 7.3's wont run if it detects no-oilpressure, and you have to disconnect the Batt. cables to clear the puter.
Just my 2 cents seems how ya gone through the mechanical stuff, maybe hook up a OBDII to it n see what it finds. Good luck, hope ya get er up n runnin soon! n hope its somethin simple too at that!
Id try to clear the puter first thing.
:draw
on edit, If he really gave the ether to er, its gunna stink out the pipe untill everylast vapor of that stuff is gone!
Where exactly r u guys? if my truck was runnin (got probs too!) n I had my tax money id grab my OBDII scanner n drive down there!
