TD4 non runner


Accelerating Away

I've just got landed with the job of looking into a TD4 non runner that my mate has just bought. ( Don't worry at the price it is worth it)

Before I start prodding around with the mutimeter are there any glaringly obvious bits to look for , Ie fuel pump operation, ie fuel output. ( sounds like on other threads there are 2 )
Or voltages at certain points.

Thanks I know its a bit like "how longs a bit of string"

Another project!!!, just finished changing the evaporator on my P38 , what a s** of a job. just managed without taking out the column. still took about 16 hours.
Injectors are a big problem, you can check them by removing the spill pipes from the top of each injector, clamping the spill pipe before the 1st injector connector, and cranking it to see if any diesel flows out of the injector spill offs. If there is a lot of fluid coming out of an injector spill off when cranking its a good indication to it being dead. Thats most common really. Obviously check the fuel pump is running (osr wheel arch).
Another thing to check is the wiring onto the fuel rail pressure sensor, they are prone to corrosion in the plug.

Low pressure fuel pump will either be under the OSR wheel arch or in the engine bay, I sell quite a few engine bay ones. The change point is roughly 2002/3.

Thanks will look in these area's.

Hopefully my greasy paws will be let loose on the beast this week.
