2005 Ford 6L no start when hot.
Hi yall new to the forum and really hoping somebody can assist me is figureing out exactly what is wrong with my truck.
I have had this truck for 2 years and the hot start issue started about a month or so after I bought the truck.
This is the complete list of parts that have been replaced and still continues to not hot start:
Stand Pipes/Dummy Plugs
all injectors re-sealed
New STC Fitting
New Branch Tube
Since then I recently attempted to save myself a ton of money and diagnose the truck myself. I pressure tested the systed with the IPR activated, while cold, and it was air tight. I tore into it a little further, I visually inspected the orings on the new stand pipes and dummy plugs, and while re-oringing the injectors the rings I pulled off were brand new.
I pulled the LPOP and inspected the gears. There was some verrrrry minor knicks and scratches in the gears but that was it, I was told the gears are fine and to just put them back in.
I was guided into thinking that I may have initially replaced the HPOP with a weak pump from the get go, so I replaced the HPOP, IPR, STC and resealed the injectors and put the truck back together.
Truck cranked up after 7-8 long cranks and sounded a ton better than when I took it apart. Now that the truck is back together it still does not hot start... If I am missing something please let me know, I plan on air testing the system while its hot to see if that will find the problem but other than that I am beyond stuck. I have also attempted to start the truck hot with the ICP unplugged and no dice there... it starts better with it unplugged but not right away.
