- Check and see if the fuel shutoff valve is closed.
- Check and see if the fuel is either stale, or at an improper fuel level. Drain the tank if necessary of all fuel and refill.
- Check if the engine oil viscosity is correct or not, and if not completely change the oil in the tractor.there
- Check and see if the fuel filter is plugged, and if necessary place.
- check if the air intake filter is plugged, and if it is clean or if necessary replace the air filter elements.
- Checked to see if any of the fuses have blown and if necessary replace one or all of them.
L3400 – tractor won’t start, just clicks
Check the following
- Could be potential battery issues. Check that all the motor and battery connections are clean and tight.
- Check the battery voltage and its holding power and replace it necessary.
L3400 – tractor cranks but will not start
- The fuel may not be getting to the cylinder. check the fuel level, the shutoff valve and the fuel filter.
- Check the air filter. It may be too cold for the cylinder to combust mixture of air and fuel.
- Move the throttle back to idle and then half throttle and attempt to restart
Starting diesel engines in cold weather
- Use proper seasonal diesel blends. Winter blends have certain additives to ensure that they remain liquid when it is cold.
- Watch and check for bio diesel percentages
- idle the engines for a time before using, this increases its efficiency and range.
- Maintain the cooling system properly. Check the overall level and quality of coolant.
- Use various engine starting aids if necessary. Some of the most common are glow plugs, intake preheaters and block heaters.
- if the engine fails to start, this could be due to the cold start system malfunctioning, the fuel injectors may be dirty or there may be a faulty switch.
