OT:Makes me feel stupid

I am at a complete lose on this one. As what I know about Truck diesels engines would not even fill a nimble and that would run out!! :>(

Also has an excess amount of white diesel exhaust. seems way more than normal... Thanks

Ok, young girl is beyond school age, she was returning home from a one week Carpentor Apprentice class in Portland,OR.

I will check out suggestion given on her truck tommorrow and post results as I find them. Again thanks everyone.

Still feel as dumb as a box of rocks..:>((

If so they came out in about 1983.

If the IP still has the original plastic governor damper ring, the problems she is having are classic symptoms of a failed plastic ring that has gotten brittle, broken up into what looks like coffee grounds, and has plugged the housing pressure regulator/fuel return fitting at the top of the IP. When no fuel can be returned to the tank, the IP ceases injecting fuel, and the engine shuts down. Timing advance is affected, causing smoke before the engine shuts down.

You can remove the fuel return hose, then unscrew the complete fitting out of the IP, and look for black plastic chunks in the valve/fitting. If you clean them out, it will run again, for a while. However, continuing to run it without rebuilding the IP will result in governor parts that are supposed to be cushioned by the plastic ring banging around metal-to-metal, once the ring completely breaks up.

I dunno, but it sure sounds like the injector pump up and went south to me.

Will run some to the other suggestions down before we cross that bridge.Thanks

Above based on obvious of checking coolant and engine oil.
Post back when you get it figured out.

Symptoms are hard starting, won't stay running, blows smoke all kinds of colors. Bring tanks to halfway mark all is well.

My repair manual only shows the one on engine. But I do not have manual for older Ford truck, Mine is 86 to 90.

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.
