Thread: Troublesome TD5

Thanks Graeme, point taken in relation to the air. I will continue to try starting it this week. The fuel pump seems to be making some strange noises though.
If you remove the injectors from the motor does it cause all the fuel in the head to drain into the nearest bore?

If I have no joy Stevo has kindly offered to come over home with his ecu program and other landy bits on the weekend.

Cheers Steve.

Fuel will definitely go into the cylinder if an injector is removed, and from there into the sump to dilute the oil! The seal under the injector should be replaced whenever an injector is reinstalled to prevent fuel leakage.

Nanocom would be very useful for checking the afore-mentioned crankshaft position sensor operation as that is the only critical sensor. Nanocom cannot check fuel pressure, but as you have some fuel getting to a removed injector, it should be enough to run. Even a dud throttle sensor wont stop it from starting and idling.

Other than that, it has to have enough compression, which can be compromised if the oil has been allowed to drain from the valve lash adjusters (similar to hydraulic lifters). I've not heard of this actually happening but there is a warning in the workshop manual about storing lash adjusters upright to prevent this and if the engine has been upside down for some time then maybe it could happen.

Hopefully its just something simple.

Thanks Graeme,
Engine was delivered on it's side from Sydney and leaked engine oil. If oil has leaked from the lash adjusters is it possible to access them in order to top them up or attend to.
I shall replace the copper washers on the bottom of the injectors also.

Regards Steve.

there is a way to purge the fuel system on a Td5........


to get the air out.......press the throttle flat to the floor........
then switch on the ignition and crank the engine.......this will purge the injectors to get all the air out.......


DO NOT DO THIS if everything is working fine as there is a strong chance you may hydraulic the engine........

The proedure for bleeding is actually:

Turn ignition to position 2 for 30 seconds.

turn off ignition.

Turn ignition to position 2 and repeat 6 times in total.

floor throttle

Start cranking, and as soon as its is cranking on all 5 cylinders bring the pedal back to 50%

If it fails to start repeat entire process

Dont crank for more than 20 seconds at one time.

If you do this entire process when the car is fueled normally you will flood it.
