hi all,
anyone kno what the symptoms are for a bad fuel pump relay and where this is located,
my jaguar x type 2.0d starts up fine while driving after engine is warm will cut out and wudnt start, as if there is no diesel inside when there is half a tank,
jag man had pluged in computer no fault code recorded, replaced parts : crank shaft sensor and fuel pressure regulator and still doin the same,

engine cuts out with flashing glow plug light, this must be something electrical as it only happens when the engine is warm and sounds like its trying to start when attempted- sounds like theres no fuel inside it,
has any one come across this,.
anyhelp will be appreciated as i have ran out of ideas- can it be the injectors or any thing to do with the pump jag man had done all sorts of test and said the pumps fine as there is power and pressure from it

:-(

thanks

It could be something as simple as the fuel filter.

Hi thanks for the reply,
the fuel filter has alredy been replaced, any other simple things i can replace?

Might be worth checking that the plug on the fuel rail itself is making good contact. (If you have not already done so)

 

[bloders]

they dont have an electrical pump on them,

Pressure - how much? I don't understand the "power" bit! 'Fine' is not good enough!

IIRC similar symptoms have been found to be caused by a dodgy cam sensor (or it's wiring) by a few members on this forum. Only trouble is with the new search feature we now have I can't find the relevant posts........

I think the later and more reliable sensors are grey, compared to the earlier black ones. They were also cheaper if bought from a ford dealer (under £20)

I agree with jimbo 20. I had exactly the same symptoms as you with my 2.0D a few years ago. It would only cut out when warm, Leave it for about 30 minutes, then it would start. Usually by the time the AA arrived! Give the cam sensor a go.

thanks mate will giv this ago hopefully it works, btw does any one know if u can access the fuel pump from the top of the tank (under neat the rear seats) or this one of those big jobs were the garages are gna rip me off, and anyone know ehre the relay is for the pump?

 

[jimbo20]

AFAIK and as bloders stated there is no electric fuel pump on these models....

 

[miz]

sorry for this silly question, but what does this mean 'no elctrical fuel pump'

 

[bloders]

There is no electrical fuel pump...
The pump on the engine sucks the fuel from the tank all the way - one of the reasons why they are a pain to change filters on as they need bleeding etc.

theres a relay for the 2.0 diesel x type jaguar under the battery tray for the diesel pump

Welcome to the forums!

theres a relay for the 2.0 diesel x type jaguar under the battery tray for the diesel pump

What does the relay do? There is no electric pump on the diesel x-type, there is only a mechanical pump driven directly from the engine.

The relay is for the glow plugs.

Aw, you spoilt it Roger.

 

[rchiv]

Sorry

Roger

 

[nicam49]

I understand that the earlier TDDi engine has the electric pump relay fitted under the battery. Maybe that's what you're thinking of?

 

[rchiv]

Not in Jaguar or ford, All their Diesel engines have mechanical pumps and the only relay required was for the Glow Plugs.
