Hot starting problem
My cousin's got a 1992 f250 with a 7.3 nonturbo manual shift.
We've worked through the bugs on it got it going.
He has one problem left on it that's got us puzzled. I know it's got to be something simple but we can't find out what it is.
After he runs it awhile till it gets good and warm then shuts it off. If he goes back to it while its still warm, it won't start..unless he roll starts it down a hill for about 3 feet then it'll start right up. The batteries are a couple months old and the wires are clean, tight, and coated with white grease to prevent corrosion. The starter kicks over quickly hot or cold.
Could someone please tell me whats causing this? Or has anyone had the same problem?

I have heard of a worn out injection pump causing this. I am trying to think of a thicker fuel you could put in the fuel filter when it won't start, to see if that's the problem. You could take the filter off, pour the diesel out, and fill it with something like a quart of kerosene, new motor oil or something like that.

General concensus seems to be a bad injector pump. If that is the case why does it start after droping into gear and rolling just 3ft?

RPM's ...
You might find it'll start better with a new starter, cables and batteries, but likely only for a short time.
The IP is worn out, when it gets warm and expands it can't pump the pressure at low RPM's.
