See my sig for what I am referring to.

Recently when towing moderately for a couple hours, about 5000 lbs at highway speeds in 80+ degree weather, I stop the truck after normal EGT cooldown.

About 10-15 minutes later when I go to restart it, it just cranks. I stop for a couple seconds and try again and it cranks and almost starts... then I stop for another couple seconds and try again... it normally starts then and runs fine. I can recreate this again an hour or two later the next place I stop.

When cold, it cranks over and starts right up normally.

Any ideas?

- My fuel pressure is a constant 15-16, but I have heard my return banjo bolt on the VP44 could be bad - no details on how this would cause hard start tho
- I have not checked codes but will report if I find any

Truck has only 71,000 miles.

 

Please post your findings after checking the codes, could be lots of things wrong there.

 

i have been fighting this exact same thing for a while now and believe me i have tried just about everything, here is a good link to the hot start reflash that is supposed to help...

lotero,

Thanks for the information... I followed it and it definitely applies to my truck as it was built in 2/00 and my Engine # falls between the range they give in the TSB.

Have you not tried this TSB yourself?

I think I will have to give the dealer a call next week after I get back to town and try to get this done. That should be a pleasant experience!??!! HA!

 

yea mine does too, and no i havent tried it will soon though, good luck with your dealer, i have "a friend in the business"

 

Hope you are not showing that dreadful po216 code.

 

it sounds to me like a vp44 going. I had that problem on mine when I had the 24 valve in it, and changed the vp out and it was gone

 

Well, the truck has been stopped and started several times since these symptoms occurred 4 days ago, but there are no codes... just "P done". I am leaving on a trip this weekend again for 1300 miles round trip. Maybe it these starting issues will occur then and I'll stop to check codes.

 

my pump never left a single code. It just kept getting worse and then I started getting the dead pedal. I replaced it before it left me stranded.

 

good (or bad) to know. Thanks Gabe. Crap... oh well, with 6 years and 71,000 miles currently, you'd think I'd still be under warranty from what I read in other threads regarding the 8-yr 136,000 mile warranty on the engine.

BTW, how long (miles) did it take after you first noticed this issue to finally get bad enough that you replaced the VP?
