Why does my Ford Galaxy TDI run on with a jet engine like sound, when I switch off?
Answers:
on all diesel engines you have a fuel cut - off solenoid on the side of the fuel pump. This may be the problem. One test to see if it is working is to lift the bonnet and listen closely around the fuel pump while someone else turn the ignition on. If you hear a 'click', this indicates it is working. Another problem may be you have a blocked breather system. Clean out alll air pipes.
Mybe your injectors or turbo arent cutting out properly? Take it to a dealer sharpish !!
can you not just go to a mechanic shop?
You mean the engine keeps running after you turn off the ignition? Its called dieseling if it only runs for a short while after turning off the ignition. This condition can occur for a multitude of reasons:
Built-up carbon in the ignition chamber can glow red after the engine is off, providing a mechanism for sparking unburnt fuel. Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the pistons and valves. Similarly, non-smooth metal regions within the piston chamber can cause this same problem, for they can glow red. It has also been suggested that an improperly rated sparkplug can retain heat and cause the same problem.
A carburetor that does not close entirely can contribute to running once the engine is off, for the extra fuel and oxygen mixture can combust easily in the warm piston chamber. Similarly, hot vaporized oil gases from the engine crankcase can provide ample fuel for dieseling.
Incorrect timing.
An engine that runs too hot or too lean may produce an environment conducive to allowing unspent fuel to combust.
An idle speed that is too fast can leave the engine with too much angular momentum upon shutdown, raising the chances that the engine can turnover and combust more fuel and lock itself into a cycle of continuous running.
Google it
Nackered turbo??
With any Turbo Charger you need to run the engine at idle for 5-10 minutes when you first start it cold and then run it at idle for the same before you shut the motor off. This allows the Turbo to cool down and prevents damage to the Turbo and Intercooler.
soungs like your fans are still running.
If you have electric fans.some cars have a heat sensor and the fans will run after the key is turned off.
Once the car cools down to a certain temp they will shut off.
to much fuel getting through posibly a relay gone or senser
get to ford now and get it fixed
How long does it run on for? And is this a new development or has it always been that way? Turbo's keep running for a short while (20seconds maximum) even after you cut the diesel, especially if you have raised the engine just before you cut it.
If it is a common rail version, I suggest leaving it idling for 30seconds to a minute before you switch off.
