My cab will not start!
NOTE : In 5 years and 4 cabs, all that is described on this page happened to me. I had to call a tow truck twice for the very same failure: my starter motor's excitation lug gone loose!
1. The engine is mute, the starter motor is not turning over
The most common cause of failure is the battery which has discharged during the night.
The battery, also called "starter battery" on a diesel vehicle is strongly requested at startup, by both the starter and the glow plugs.
Also check the connections to the battery.
A discharged battery can also be a sign of an alternator that no longer charges!
What should be checked apart from the battery?
2. The starter motor turns over but will not start the cab
A cab in good condition should start on the 1st turn of the key, without having to press the accelerator.
If the engine turns over, clouds of smoke below from the exhaust but the engine will not start, it is often a sign that the glow plugs are worn.
3. The starter motor turns over the engine starts but is soon choking
This is a sign of poor fuel flow to the engine.
4. The engine is running but releases loads of white smoke, the vehicle is sluggish on the road
This may be the sign of a blockage of the fuel line: either the line from the tank, or the priming pump above the fuel filter is blocked, the engine then draws in water from the separator at the bottom of the filter instead of fuel, provoking these large clouds of smoke!
