Got a JLG with a cummins QSB4.5 engine, so the engine radiator was pressure washed, machine started and moved a short distance and shut off, started back after trying for some time would idle then shut off under load, now it doesn't start at all. Active codes for all injector drivers and intake mass air flow. Please advice on how to go about troubleshooting issue. Cranks at around 160rpm and builds around 5000psi fuel pressure.
