I have a 1994 Ford F-350 7.3 idi turbo diesel. When I got it I had to put an fuel line on it and after I did that it ran for a day and I drive it around with no issues till that evening then it died on me. So I had it towed home since then I’ve replaced two injectors a fuel filter a mechanical fuel pump and the serpentine belt and it was running down the road for about a mile then it would die. Now I can’t get it to start at all and when it does start it blows white smoke because of a lack of fuel. I know hardly anything about diesels I’m 17 and In over my head this is my first diesel truck. And I need help to figure out what the issue is so I can hopefully fix it and sell it. Any ideas on what may be wrong...or things to try that don’t cost an awful lot of money. I don’t have money to spend in all honesty because I don’t have a job because I don’t have a vehicle to drive. Any help would be greatly appreciated.
