Check the high pressure oil switch next to the glow plug controller. if the switch is bad you will not get any fuel to your injector pump. unplug the molex and jump it out. this will bypass the switch. if it runs, just buy another high pressure oil switch. good luck!
I pesonaly have burned up two pumps if it has a code pertaining to optical sensor your injection pump is no good,common cause is a bad conecction at oil presure sensor on the back of the motor orange wire it provids power to the lift pump trust me
I am having the same problem have plenty of clean fuel to the ip but nothing coming out, pump, pmd, lift pump and oil sending unit all replaced within last 1000 miles im going to check tommarow for return line blockage and when mine left me on the side of the road it had no dash lights whitch leads me to think ignition but havent had time to really look at it. but if you have fuel to the ip then its not your oil sending unit sensor or watever you want to call it
