Engine Troubles? M25XP not starting

[Ron Hill]

Ben : Glad to hear that you got the engine running.

Just make sure that you pull the fuel tank and get rid of that old fuel. And while the tank is out I'd clean the inside of the tank. 
Also check "critical Updates" and make sure the screen is off of the fuel pickup tube.

Congratulations!!

I was unclear in my questions.

The positive you 'wired to the solenoid' - was that the harness positive? Where was that previously?

The negative you wired to the terminal block - that was  the harness negative?  Where was that wired to previously?

I took short leads direct from the battery terminals to the solenoid + (where harness wire was going) and ground block -.

Ben,

Glad to hear you got it running.  Your "very last thing to try" seemed to have been the first thing that was suggested, both in this thread and in Critical Upgrades: the electrical connections.

Are you now going to re-winterize the engine?

[Ron Hill]

Ben : The speed at which a diesel turn over is not particularly relevant to having it "fire up". 

I believe that you probably finally got some new clean fuel to the different clean injectors and the engine started!!   

My thoughts

Stu: Stubbornness on my end maybe?!

Ron: I think you're right, plus the better electrical connections.
