Ok, around Christmas, I did an injector/IP change on my '94 7.3L turbo. We also changed all lines, o-rings, fuel pump, filters, radiator, glow plugs, etc. The truck runs great after the work, but one thing doesn't: it won't start when hot. It basically happens after the truck has been sitting hot for 30 minutes.
I've tried the water on the IP trick, and it starts fine. So, I know that's the problem. But, the issue is, we changed this IP about 6 times, different parts, different rebuild shops, new and used, and we still have this issue. The mechanic at the pump lab finally threw up his arms. All of the pumps tested fine, but had the same issue on the truck.
Other than the hot starting, the truck runs great. It has lots of power, some black smoke really pushing it up hills, but otherwise no smoke, no issues.
I can start it cold just fine, run it up to temp, then shut it off. If I start it again in 10 minutes, it starts. If I wait 30 minutes, it won't start, just cranks. I basically have to take a bottle of water everywhere I go, just in case.
It is very annoying, and we've tried so many things, I am kinda lost. The mechanic thought the pump was the issue, but after changing it out several times with several different pumps and rebuild shops, and all the pumps tested fine, he thinks it has to be something else. We've basically been fighting this since December. I'm starting to think I just need to add a few quarts of motor oil in my diesel tank at every fill up.
Any idea what else could be wrong with it?
