Hard start when warm

[Paul Amestoy]

1998 K2500 6.5TD 135K miles.... I have seemed to fix most of my problems ( for now) but I have a new problem with startup when warm....it will not fire and seems to be lacking fuel.... Starts great when cold.... but when Hot it will not start / or start after 10 minutes of cranking. which will eventually cause yet another problem... any ideas? :confused:

Good move also posting on the 6.5L forum, got good responses there. Could use 'search' function for , say "hard start, warm" at 6.5 forum. Suggest read recent posts by "Ryno" there. If certain have fuel pressure when warm [not air in line to injection pump] then Charlie P / Kowsoc's recommendations need action. I'd check fuel press and flow when problemmatic; then reseat electric connectors, FSD fastening , then pump....

Thanx for helping, Tom.

As most of you know, I like mechanical injection pumps and try to allow the computer experts to address the DS4 issues.
