Finally had a chance to get back to this problem. Process of elimination here but finally think I found the problem after diagnosis of the 12 v Fuel pump. Passes a continuity test when isolating the Control Box circuit from the pump but fails when connected back to the pump. Also appears that no fuel is being pumped. Well the assumption....only and assumption because who knows what else may be lurking in this Oldie but goodie 8KW is the pump is failing or sending a dead short back to the Control relay tripping the DC breaker which in turn disengages the Fuel Solenoid causing it to shut down after running a few seconds. Pump will be ordered here through Cummins South Miami tomorrow will update after the install.
