97' 6.5 gm diesel

I have a 6.5 that will run perfect for an hour or so and than dies and won't start. Has a new injector pump, tubo solenoid and has no codes on the computer. Anybody have any ideas?

My first thoughts would be a lift pump (transfer pump), fuel filter, air leak in the transfer line. If you're in very cold weather (low teens and below) plugged filter either due to ice crystals or clouded fuel, especially if you're using B200 or heavier bio.

For the latter, change the filter, then if it reoccurs, use an additive like Howes (for straight petroleum diesel) or Arctic Express for Bio-diesel. If you're in a pinch for additive and it's available use about one quart of E85 to 100 gallons of diesel. The alcohol in it will get rid of the ice crystals/water and cut the gelling.


Hope this helps,

Bob

Thanks for the input, filter is new and I live in florida. Although the truck came from up north, I will check the possibility of cracks in the fuel line. I am burning diesel fuel for now, veggie mix later. Thanks, HJ.
