Doosan DX235 died and will not start: are all injectors likely bad?
Short Answer
It is unlikely for all Doosan DX235 injectors to fail at the same time without a cause such as fuel contamination, water, electrical control loss or a rail-pressure problem. Before buying a full injector set, verify fuel quality, rail pressure, return leakage, cam/crank sensor input, ECM power and fuses.
What To Check
- Drain and inspect fuel and filters for water, metal or contamination before fitting new injectors.
- Compare commanded and actual rail pressure while cranking.
- Check injector return flow, cam/crank sensor signals and ECM power before replacing all injectors.
