My brother in laws 1997 7.3 died on him last night(sort of). He said that the other day when he drove it that his filter light came on for a few minutes then went off. He planned on servicing it this week end any ways. I found out he hasn't changed it in over a year
Anyways, he went to leave last night and he lost power and developed a bad miss(like it lost more than one cylinder). He was able to turn around and get it to coast back into his yard where it wouldn't crank back up. He went on to work in another car and when I got home I went to look at it for him. His fuel filter was solid with black gunk, and rusty water. I drained it ,cleaned it, made sure it was pumping fuel and put the new filter in it. It took a second but it fired up on its own and idled. You can rev it but it has a very bad miss and if you wot it takes a few seconds to build rpm's and even then you can tell its lost most its power. What are his options?? Run a cleaner and hope for the best? Pull all the injecters and have them cleaned and rebuilt? Or ?????
Side note--All the harness looked good and I didn't have a chance to check for codes. Since I found all the crap in the filter I figured that was the issue.
