ok, now what? 7.3 no start
I have here a 1997 7.3 that was towed in and wont start. So far we have found:
Burned wire going to glow plug harness, repaired that by replacing valve cover gaskets and harnesses.
had no oil pressure from high pressure pump, replace pump.
removed all injectors, visual inspection (saw nothing)
tested for fuel pressure, has 45 psi cranking.
this thing WONT start. previous person repalced idm,,it was obviously bad, the scanner wouldnt even do a buzz test on ANY of the injectors. re replaced the idm again and get a buzz test just fine and it passes with no problems.
crank sensor is fine, it shows cranking speed while cranking.
engine WILL run on an external source, i know you are gonna cringe, but it DOES run on either with the glow plugs disabled. it will not stay running, dies immediately when nothing is sprayed into intake.
we are at a complee loss where else to look for a problem. any help would be appreciated!
