i have a 93 6.5t that i just bought from the original owner. it runs and drives great till its gets hot. it will start immediately but if you wait 20 minutes it will not. i have read some of the posts on the subject but still need some input. thanks.
i have verified operation of the lift pump. cranking speed is good. oil pressure per gage is present. still no start.
after reading this somewhere i tried spraying the ip with something cool, i used carb cleaner, and the truck started. could this be an internal ip problem?? if there something else i can check before i replace the ip?? milage on the truck is 119k. seems early for ip failure.
previous owner was not helpful, he thought his glow plugs and controller were bad and paid someone to replace them. i have not checked fuel pressure at the filter yet but i can. oil pressure sending unit??? thanks
