01 starts then dies before warmup

[Comdivers]

My 01 has 200k and mostly orig. engine parts. Very cherry! One problem however, I did a lot of searching and found a lot of references to cold weather but I live in Florida! When the truck has been sitting over night or for a few hours, or on a incline it will start and then die unless I pump the accel. like mad until it starts running smoothly. Took it to Ford but that was a waste of time and money! Still have problem...
Thanks

When was the last time you replaced your fuel filters? The fuel pump could be getting weak.

I just replaced it and it needed it. I've only had this truck about 18 months and it started right after I got it. I had such a bad experience with Ford however, that I have just lived with the problem - just remember to pump the throttle as soon as it starts. But last Sun I was parked on a inclined driveway and when I came out it did it and since it was warm I failed to pump it. It hasn't run since...

bump this up for ya man. Hang in there. The Ford is a good truck. Hopefully a tech will chime in and give ya a little more info than i can.

I found a reputable diesel mechanic and left the truck with him for a week for eval. Today he said he is 85% sure it is a weak low pressure oil pump which he is replacing. Let you know if it solves the problem when I know...

HOPE THAT DOES IT FOR YOU.

Looks like the problem is fixed. Started every morning just like it should. Low oil pressure pump is the only thing he replaced. Now I am going to have him re-install the DIABLO chip Ford talked me into letting them remove (for a nominal fee of course).
