Okay, I set a challenge who I will call the Ford genius, the reason for this is because about five or six people have looked at this truck including Fords, engine builders, and diesel specialists also myself and no one can figure out the problem.

The problem

It’s very hard to start and when you do eventually get it started, it runs perfect with no issues whatsoever drive it for 5min or 1 hours it will simply restart instantly, but this is were the problem lays, leave the truck siting overnight and you’ll have the same program starting problem

Literally everything has been changed on this Truck. Let’s give you a list.
fuel filter
fuel stop
fuel
fuel lines
cam and crank sensors
low and high pressure pump
all injectors
head and head gasket
Then all the ecu pin outs checked and sensors check fuses relays
lives and earths all good

There is one thing that I can see that’s happening all the time the truck is not firing the noid testing light 💡 isn’t glowing when it try’s to fire up the noid light as a dim glow, when it eventually try’s to firer up properly and starts the noid light as a good strong pulse light

There no real for codes being shown
Occasionally communication can and occasionally speed sensor p1934

good luck lol
