Hot Restart Problem

[mosesburb]

Cold starts are simple--wait for glow plug light to go out, bump starter and it runs--smoothly. Hot restarts are a different story. Fuel pedal 1/2 way to floor, lots of cranking and eevveennttuuaallyy it will start. Keep foot on throttle and it will stay running. Let pedal up and it will try to shake the body panels off of the truck, then die. Keeping engine speed at 7-800 will keep it running--quite smoothly. '84 6.2L "J" with Banks turbo. I bought it about a week and a half ago. Previous owner never encountered this problem (have absolutely no reason to doubt him). I changed the fuel filter and thought it made a difference, but not so sure now. Pressurized the fuel tank with 5psi of shop air, looked over entire feul system and found no air leaks. Same results at 10 psi. Off idle it runs fine, wouldn't even know there was a problem, but at idle one is quickly reminded. Seems to get better after driving awhile.
Any ideas??

try this,

take 3qts of ATF (trans fluid) desolve into a gallon or two of diesel and pour into your fuel tank. it will "thicken" the fuel up some. It might smoke some, but will not harm the engine at all. If hot restarts are better with this, than your injector pump is worn out and needs a rebuild.

I actually tried a couple suggestions in that thread already and they had no effect. It will start if pedal is applied, but after it finally starts it runs like poo. Take it out and drive it--no problem, but stoppping and idling will remind you quickly that there is a problem.
I haven't tried the ATF in the fuel yet. I did advance the IP tonight and that made a big difference in performance, but still does its funky hot restart after heat soaking for a few minutes.
