Alright here we go...might need an engineer to figure this one out..

Workin on a 96 7.3 powerstroke came in with a complaint of it not starting sometimes...when I started it up to pull into shop it fired up immediately...couldn't get the problem to occur. Hooked scanner up to to read codes and look at data pry had the key on for 3 min More than enough time for the gp coil to cycle to starting it to read data and cranked for about 8 seconds then started loading up and puffin smoke like crazy out the exhaust and even the wastegate on the turbo. Pulled valve covers and tested glow pugs with test light found two open ones thought maybe two cylinders being cold would cause enough to make it load up...put back together and problem never accused...week later guy came back for same reason this time I went to start it and it cranked for awhile and loaded up again...looked at turbo down pipe and saw fuel running out of it...looked at manifolds and on the passenger side #7 and #5 had fuel...decided to pull injectors found back two with ripped o rings replaced o rings on all 4...thought for sure it would fix it...nope...did every test in the book I could think of checking wiring from idm to each injector found nothin so threw a new idm at it didn't change a thing...
