The solenoid on the side of the inj pump is just a cold start solenoid, it just advances or retards the timing for easier starting.
The solenoid by the lines is the shut off solenoid, some are powered (12v) to run and some are powered to shut off..

Thanks for the wiring schematic, and thank you Pump guy! All right, its running now with that switch/sensor bypassed, and power now to the shut off solenoid.
But the question is what was that switch/snsor on the side of the head, that the shut off solenoid was getting its power from? Iam not sure that wiring schematic is for this tractor. This tractor has the thermostart, no glow plugs.
I took a few pics of it to give an idea of its location on engine. its the one with the black twisted wires. This feeds power to that shut off solenoid.

Is the black twisted wires going to your thermostart.?
If yes, something is bad wrong..
The thermostart should only be active when u turn the key switch a certain way.. either to the left or to the right, just before the start..

No. Power is going to that switch/sensor, but nothing is coming out of it. One is hot going to the sensor and the other black twisted wire feeds to the injector pump shut off sol.
