I have a 92 f250 7.3 idi. The truck starts everytime when the motor is cold, and by cold i just mean sitting overnight. It hasn't been below 75* since i bought it. If i go drive the truck and then try and start it a half hour later my WTS light doesn't come on (which i don't know if it should or not)and the truck will not start unless i crank and crank and crank. The day i bought the truck the gas gauge was on E so i was going to try and make it home bc there were no diesel stations nearby. I got stopped at a light and the truck died and it took me a while to it started again and i quickly pulled into a parking lot and shut it off and when and got a gas can. Do you think it sucked air in the system? Since then i have filled the tank and drove the truck several times and put a total of 75 miles on it. I have also replaced the batteries, and the GPC and had the oil changed. What is my problem. This only happens when the motor is hot. Thanks in advance for the help.
From what I've been reading here, it seems a no-start condition when fully warmed up is a symptom of a dying injection pump. I wouldn't think that if you sucked air in the lines it will act up only when warm, it should act up all the time no matter temperature of the engine.

Hard starting when warm can be a bad starter, i.e. there is more friction in the engine when warm, if the starter is bad it can't spin fast enough so the engine can fire. Pull the starter and take a look at the bushing in the bendix end of the starter.

That doesn't sound like air intrusion to me. Classically, air in the system makes it hard to start after the truck has been sitting for a period of time. It will start when warm, as air had not had time to leak into the system.
I agree with what was said above, it seems to be your IP. How many miles are on the pump and injectors?

I'm going to say everything is original. The truck only has 137,000 miles on it. Would the pump go out with that amount of miles or is it more that the pump is 16 years old?
100,000 miles is about the life expectancy of the IP and injectors. You will get more miles if you add a lubricating addivtive to your ULSD (like Power Service or whatever you like).

Check your batteries and starter. Buddy had the same issue, fine when cold, but after it was warmed up, didn't start well. Ended up being one weak battery and a bad starter. She turns over & starts w/out glow plugging when warm now.

What you did by letting it run out of fuel has nothing to do with your hot starting issues. The simplest and first thing to do is to pull the starter and inspect, that's a 15 minute job.

The batteries are brand new as of 2 weeks ago, they are motorcraft 850cca. I replaced them because when i bought the truck it had one 450cca and one 650cca. The 650 was bad so i also assumed that was my problem but after i replaced the batteries the problem still remained. I guess i will next check the starter but the truck cranks very fast even when it won't start. So no on thinks it could be the injector solenoid, i read that it shuts down the fuel and when they go back it could not work when it gets hot and there for not letting the fuel into the motor but that really would make sense if i can eventually get it to start by cranking it over and over.
i fight the same problem with my 92. It has a fresh IP and new injectors. Starts great cold, shut it off, start it again with in 2 minutes or so all's ok, let it set longer than that crank and crank and crank. I don't have any idea what to do next, as I have replaced everything under the sun that could be related. I'm open for all suggestions.
