You guys are over thinking the whole starter fluid thing, 939s are easy! get truck ready to fire, get in roll the window down take the can in your left hand, reach out and squirt a shot in the mushroom as you turn the engine over, this is much easier to do and safer for your engine than putting in after the filter. If you can't reach it from the seat as some of us can't, just spray before you sit down it still works. And it also works with the tapered screen around the mushroom.
I'm concerned about spray into the mushroom because there is so much pipe and air cleaner for it to go through.
This morning it wouldn't start again, and I removed the air cleaner to get to the pipe. I used starter fluid, LOTS of starter fluid, almost a whole can. The engine ran strictly on fluid for about 45 seconds before the diesel caught. Doing that through all that piping and the cleaner would have been a problem.
We are over discussing the tire bit. The tire was flat in GL when I picked up the truck. It could well have been moved around flat by GL flat. I pumped it up from the truck's compressor using a hose on a glad hand. The sidewall didn't look good then and I believe it let go within a couple hundred miles.
How the spare got mismatched is anyone's guess and not real important. There aren't many Michelin XL tires around and there was some work done on the truck, so I assumed they upgraded the 10 tires on the ground and forgot the spare.
The end of this story is the transmission went out 16 miles from the storage yard, costing me a last $375 for a flat bed tow. You should see a flatbed trailer that could load a 5 Ton:
