F250 Super Duty Diesel Question

My pu (2005 F250 SD Diesel w 6.0) would die at an intersection on occations, I took it in to a Ford dealership. They told me the fuel sending unit was bad and so 950.00 was sunk into that repair.

Drove back to Victoria with my DW that afternoon, towing my Flaggstaff Super Lite 5er, and it died in the intersection again.

Called the dealership the next morning, and drove the 45 minutes back to the dealership, to then have the EGR valve replaced, second on in 2 years! One in Colorado and one in South Texas.

Well, in the past 2 months, the pu has not died on me, but was hard to start. Always would start on the second or third time it turned over. After the repairs, it would take 8-10 turnovers to start. Yesterday, tried for a minute to start the pu and then it started to "click".

My question is this...Batteries (both of them) going bad? Or could they have adjusted the timeing when tring to make the pu not die, while at the dealership?

How do you even "jump" a diesel with two batteries...never needed to try, lol! Ah, for the simple days again with no computers, smog devices...just the simple old power houses that seemed to go forever!!!

Next step? Supposed to travel from East Texas back to Tennessee this coming week, after Thanksgiving, and don't see being able to get it in a shop until after the holidays due to the short work week!

Help guys...whats next, lol!

Thanks and have a Blessed Holiday!

  • Get your batteries load tested, sounds like it is new battery time. :(
  • Batteries if weak could definitely cause problems. You would most likely get more and better help at wwe.ford-trucks.com. Good luck, John
  • They couldn't adjust the timing so don't worry about that.
    The ECM looks for a minimum specific eng RPM while it's cranking and if it doesn't see it, it wont allow it to start. So batteries can cause an issue but it usually shows up in the winter when it's cold and the battery efficiency is taxed. It can also have a hard time starting for many other reasons including sensor rationality.
    Longer crank times are often the result of leaking injectors but it's hard to tell without more testing.
