Persistent E31 error code!!!!!!!!

Hi Guys, in relation to error code E31 for Nissan P1D1 series machines.
We have a real troublesome machine on our fleet. E31 code. New wiring harness, new ECM, new accel pot, used but good throttle body. Cleared VCM alarm history, cleared ECM history through 'self diag clr'. Fault still persists. Attempted the throttle dance several times with no real result. Any advise would be really welcome at this stage? Has anyone converted this model back to impco & distributor system - may save a lot of expense?????

"Unicarriers - it would have to be for a dual fuel unit also. Usually a bad cam or crankshaft sensor will throw a E-27 or a E-28 code on the dash panel... If it does not light up and the bulb is bad then it will not start also."
