Hi all,have a 3126b in 03 f750 it was running fine,after about a12 mile job I shut it down for a few minutes wouldn't restart.Cranked but no fire/fuel.Started on ether and ran fine.Shut it down when done and again no start.Tried again in the am cranked and finally caught.Seems to only fire first time ,after warmed up won't fire.Unplugged oil pressure sensor.Still no fire.Also have an oil leak from behind turbo.I cleaned it up and ran the engine with no visible leak,but after shutdown could see oil coming from behind turbo.I'd appreciate any help.

Mulchman,
Your no start when hot is a problem with the HEUI system. The problem/s could be injector seals to a bad HEUI pump. Specific testing will need to be performed and the results reviewed for the proper repairs to be of value. Thanks Frank
