Keith:

I had a problem with my 93 F250 with 7.3 Turbo Diesel in it a few weeks ago. What happened with mine was that it got to where it was very hard to start, it took cranking for about 15-20 seconds to get it to start. It just seemed like it was sucking air. After about a week it develeped a fuel leak, and then a baaaad fule leak. I went through a couple of things before I found my problem. I replaced fuel filter and lift pump, neither one helped. The problem turned out to be the caps, return lines and Orings on top of the injectors. There is a kit that NAPA can get (I can't remeber the kit name) that gets you new orings (2 per injector) caps, and new return lines for about $35-$40. OK long preexplanation there. What caused my leak, of air and fuel, according to the pump shop was the new low sulphur fuel. The pump shop said that the new low sulphur fuel doesn't have some of the aromatics that the higher sulphur fuel has therefore the orings shrink and get brittle, and then it dumps fuel and sucks air. Then the engine has a hard time running. Lesson learned from the repair. Do one side of the engine at a time, and do all 4 on that side. Get the truck running and look for leaks. Now do the other side, this makes it a lot easier to get the truck running. I don't know if your neighbor girls problem is related, but apparently the problem I had is getting to be very common with the older (pre 2000) trucks.
