The provided context does not contain specific troubleshooting steps for why the Cummins QSB 6.7 diesel engine in the Manitowoc Grove RT765E-2 might not start. However, common reasons for a diesel engine failing to start include:

1. Fuel Issues – Low or contaminated fuel, clogged fuel filters, or air in the fuel system.
2. Battery Problems – Weak or dead battery preventing proper cranking.
3. Starter Motor Failure – Faulty starter preventing engine turnover.
4. DPF Regeneration Interruption – If the Diesel Particulate Filter (DPF) regeneration was interrupted, it could affect engine performance.
5. Electrical or Sensor Faults – Wiring issues, faulty sensors, or an inactive safety switch.

If the engine does not start, checking these possible causes is recommended.
