Guess I should have started with what I have all ready done.
Upon visual inspection I noticed that the fuel lines had been replaced with 3/8" instead of the ¼" that it came with. Being the wrong size the hose clamps were cinched down till they mushroomed off the back side of the hose barb and were still not tight.
So I bypassed the two fuel filters and pump and set up a gravity feed temp fuel can. Then with fresh fuel I bleed the air screw on the pump and the injectors {While Turning the motor over} till all air was purged from the system. I checked the glow plugs and they were getting 12.5 volts. And air filter is new.
Decal on motor and air filter housing say's "DO NOT USE STARTING FLUID"
Still no start. Light white smoke out exhaust and seems like it wants to start.
In the morning my plan was to remove and bench check the glow plugs.
I will admit up front I'm a gas guy so was wondering if I might have forgot something.
Saving compression check for last because of pre-bent steel fuel lines.

And yes I know the white plastic rod from the fuel solenoid to the pump is broken but it still moves the stop/start lever the right distance.

Hey gator,
the 3/8" line they replaced in the picture is an injection nozzle return hose.
it only returns leftover fuel that was not injected by the injector pump. it will have no effect on engine performance unless air is being introduced.
more likely one or more of the o-rings under the fuel return cap has been eroded, cracked, or otherwise introducing air into the system.
the reason they don't want you to use starting fluid is because of the explosion danger of shooting start juice into the precombustion chambers and setting it off with hot glow plugs
you can start it on start juice if you disconnect the power to the glow plug relay or otherwise disconnect power from the glow plugs.
white smoke is an indication of low compression or contamination of the combustion chamber.
compression temperatures are normally in excess of 1000*F when things are right, even in the lil diesels.
it may be best to think safety when performing the compression check.
when you remove the steel lines, the fuel pump will still develop thousands of pounds of pressure that will exit the pump through the fittings whether there is a line attached or not.
you'd do best to plan for that
the injectors(nozzles) in this engine are (High) pressure operated, the timing is set by the fuel pump.
i'd consider extraction of the glow plugs and go from there
i hope the info is helpful
