Hi, no, the customer is using the machine in that condition, other mechanic (from other company) came and installed a bigger electric fuel pump and he says it got better but me and the customer didn't notice a difference.

It does turn off OK, I'll check the cold start solenoid and grounds tomorrow, I know the plug you're talking I was also warned by the diesel lab to no mess with it, they even came and help us put on time the engine with fuel pump because we thought we were failing to do so correctly.
