I've been having problems M1151A1 and a M1097
The M1097 has had the engine replaced, and injector pump replaced twice even after the new engine swap. It cranks and cranks but does not turn over. the mechanical fuel pump sends fuel to the fuel water separator and then to the injector pump. It does not push fuel out to the injectors
we have replaced
PCB Box
Semiconductor Diode
Glow plug controller
injector pump
and engine
I've also tested the power to the 2 wires going to the injector pump and both have enough power to work.
Does anyone know what else it could be.
The M1151A1 has the same problems but we have only replaced the injector pump. and PCB
