On the rear of your transfer case, there is a round metal tag with the model number. Should be NV231 or NV233. If it is electric shift, the transfer case is not adjustable.
Trans linkage adjustment is straight forward in the link. When it does not start, does the starter turn the engine over like normal? (cranks but does not start).
The ignition must be in the OFF position so the red pump prime wire can activate the pump. If it does not activate, there is a circuit problem for the pump. Grey is power to the pump, and black is ground for the pump.

At this point the red pump prime wire is not starting the fuel pump.
Again, I checked for power at the rely and we had 12v there and replaced that relay. I have crank, no fuel pump turing on with red pump prime wire or not. I check for power at the fuel pump connection and the gray and black wire, NO power.
Again, thanks Capt..

Ignition OFF, battery voltage applied to the red wire: trace the grey wire back to the pump module. Gotta be battery voltage at the grey wire on the pump module.
