Starting problems only when is hot

[conan]

Hello!

My name is conny and i am from Sweden, sorry for my bad spelling

I have a very big problem on my pickup a C2500 95- 6,5 TD
cold starts are no problems but if its hot and i shut it off and wait about 10-15 minutes and tryes to start it it starts!!! but it will only run for about 20 sec
then it stops but i can start it again but it will only run or 5-10 sec
and i have a FSD mounted on the intake
Any good ideas?

Probably the FSD is going bad.

Try a fresh DTECH FSD mounted outside the engine bay on a cooler.

Do you think its the heat on the FSD
i think i should try to move the FSD i have
but wat am i going to do whith the cabels they are to short,best solution?

Check out this thread (http://www.thedieselpageforums.com/tdpforum/showthread.php?t=2938) first. Not much to go on, but if I had to guess, I'd guess the problem has to do with delivering fuel to the injection pump rather than the FSD.
