How do you start a diesel after it ran out of fuel?
Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds. If it does not start, repeat the first task and this one until it starts (cycle the key).
What can cause diesel engine not to start?
If the diesel engine won’t start, but turns over quickly on the starter motor, then a fuel problem – as above – is the most likely cause. However, in cold weather it’s worth checking the glow plugs: these are pre-heaters fitted to most diesel engines to warm the air in the intake to improve cold starting.
Can bad diesel cause no start?
Fuel Delivery Problems On newer diesels with electronic injection pumps or direct injection, you’ll need a scan tool to make any changes. Air in the fuel can also be a cause of hard starting or a no start condition. Air can make the engine die after it starts, and make restarting difficult.
What happens if you run out of diesel?
When a diesel engine draws in air instead of fuel, both the fuel pump and fuel injectors can become damaged. As well as this, when you run out of fuel in a diesel engine you might need to bleed the system to get rid of the air before you can top it up again with diesel, which is a job for a specialist.
