Engine starting and smoke
Check battery condition, fuel supply, filters, air in lines, and glow plug or cold-start system if fitted.
No-start conditions commonly come from fuel starvation, electrical cutoff, or air in the fuel system.
This can come from restricted fuel flow, low fuel pressure, air ingress, or engine management or emissions faults on newer machines.
Black smoke usually means too much fuel, not enough air, clogged filters, or turbo or boost issues on turbocharged models.
White smoke often points to unburnt fuel, cold combustion, injector issues, coolant entry, or compression problems.
Common reasons are dirty filters, injector wear, poor maintenance, or excessive idling and overloading.
