I just found where I lifted the pic from my post #19- it's also from a post #19 in this thread: https://www.steelsoldiers.com/threads/m939a2-shifting-issues.213336/ Lots of good info that I used in building my troubleshooting Thanks @Elijah95

That's a good way to start the troubleshooting process. That also brought back some old, but fond, memories as a young kid helping out on the farm. The punishment for us kids running grandpa's tractor out of diesel was that he would loosen the injector lines at the IP and then he would hand us...

I'm not seeing a sensor in the TM (see attached) so not sure what you're referring to. Also, the pic of the motor is a pic I lifted from this forum and not the truck in question. I can't remember which thread I took it from so I can't give them credit. But I think you just gave me an idea...

The seller called me back and asked if I was still interested in the truck. I hope to take a look at it in the next week or so and want to be prepared in basic trouble shooting of the fuel supply system and IP. I still think (hope) it's something easily fixed... I've been reading up a lot on...

I hear ya, CSM, and agree with what you're saying. I was really hoping to self-recover the truck as it's parked in an area behind a barn. The owner said I'd need to arrange it to be towed out as a typical RGN truck/trailer wouldn't make it to the truck. So you're right I shouldn't fix another...

Thanks for the suggestions- those are great tips. I should do that to all my trucks as I'm sure there is a ton of gunk in the lines and other system parts.

I've heard of guys taking a cheap hand pump garden sprayer from Home Depot and filling it with diesel to recover tractors, dozers, etc. stuck in the field. You can easily vary the amount of pressure you have from 5-30psi by how much you pump it. The couple gallons of diesel is more than...

You know, the funny thing is I wasn't thinking too. I knew they were 1/4" tubing but I'm so used to connecting them to our pumps with 1/8" NPT nipples that I got used to calling them 1/8". <insert face palm> And yeah, we use an 8mm wrench to push against the release ring but sometimes...

That's a really slick set up! Where did you get those 1/8" push-locks? I use them for my fan misting/cooling system in the work area but the ones I use are a bugger to get undone without a lot of cussing. Hoping you know a special brand that are much easier to install/un-install....

The hour or so I spent going searching this forum led me to believe the same. I know it's always a crapshoot when buying one of these trucks but at least I'm hoping to do an educated crapshoot if I purchase. Last thing I need is another time- and money-sucker sitting out in my motor pool...

I own three M939 series trucks with the NHC250 so I'm familiar with how air leaks in the fuel supply system can cause havoc. I'm hearing the 8.3L isn't too different in that air leaks (along with a bunch of other nit-noid things) cause a lot of no-start headaches that people originally...
