Selling if I cannot find out whats wrong

I have done the one test while the truck is running and it doesn't die, and also my lift pump is wired to a switch that I turn on before I start it.
 
So the hard start and occasional stalling could be:

1. Fuel supply problem of fuel bleeding off through bad check valve, or sucking air slightly. Plugged fuel filter.

2. Glow plugs not getting hot enough, not staying hot long enough.

3. Low compression.

4. Pmd or ground issues that are controlling the ip.

Where to start? What is done to the factory air filter?
What is the fuel pressure at the ip under a Load? What is the volume of fuel the lp puts out per minute?
W/ this info we can tell you what to fix or what to look at next without wasting money or a lot of time.

Want to just throw some parts at it? Start with a new fuel filter and screen that is under the fuel filter. Next is injectors. Follow that up with a tune and turning up the ip And timing while putting on a 4" exhaust. All this will do the truck good, it just cost some cash and has a chance to fix it. Of coarse if you have low compression because the po used some starting fluid then this will not help very much at all and could make it all worse with the exception of the filter.

Even if you can't copy / paste the troubleshooting list read through it and respond. Not as easy but free... All my typos are from this stupid I phone tiny keyboard.
 
The OP must have given up on it, he is only about 60-75 miles from me and I offered to work on his truck @ no charge and haven't herd back from him.. he might have moved on...
 
No haven't moved on just got real busy im sorry guys, my wife and I run a horse and dog rescue plus a boarding facility and we have a few new boarders. Just been very busy I apologize.
