It is a diesel and all new lines and they were bleed. This is the fourth fuel pump put on it and it run for a day good with each pump, but then starts missing so bad it won't run. Had to be towed home.

Thanks for responding, I can not remember if the 1994 chevy 6.5 diesel is electronic injection pump, or is it still the manual pump, let me know and I can help you.

With 265,000 miles, how many times have you changed the electronic control box (Black)on the injection pump? You said you change the fuel filter, did you change both of them? The primary and secondary? After you change the fuel pump and it runs good for one day do you have to change the fuel pump again so it'll start up 1 2 or 3 days later? When it starts to misfire and will not run any more, do you check the fuel filter to see if it's out of fuel? When it starts to misfire do you check the voltage at the injection Pink wire? And tell me if you have an engine light on when it starts to misfire or all in all the time? If you could answer all my questions I would appreciate it, it will help me help you, diesels are very hard to figure out when they've got problems, but are still one of the most reliable vehicles.
