There'll be more to the code than just "700" - let us know.

What has been done to attempt to resolve it so far?

 

[spitfire]

Tank has been drained 3 times fuel filters changed all fuel drained from system up to pump ,managed to start it 3 times in last 10 days but wont start once switched off ,mechanic blaming fuel but has changed for fresh fuel each time have to get it into dealer just need to know what to look for before we start changing pump and injectors

Does it have a leccy lift pump on the filter housing? Had to replace ours on the tm310. Comes with a filter so don’t buy a filter with it

Has it a glass bowl water trap behind the steps?

Dodgy stop solenoid?

good question

 

[Timbo]

What is the exact fault code? it will begin with a P, and there isnt a pure P0700 code

So there is good fuel flow at the HP pump with ignition on from the lift pump?

There are some really good diagnostic flow charts in the workshop manual for fault finding all the fault codes, plus the use of the JCB servicemaster to look at live data. Why isn't the tech using these??

Since you have been at draining the fuel tank, can we presume you have had some contamination ?

If it was water, at a complete guess I'd say you've buggered at the very least the HP pump and likely all the injectors too- a quick look at live data will show what rail pressure it is building during cranking and what the SCV duty cycle is (an indication of the health of the HP pump)

I don't think we're getting the full story here.

No. it's a common rail engine.

We had a white oily sludge in the summer in the bottom of filter which caused problems cleared that, have been extra careful with fuel since putting fresh deliveries straight into clean ibc to check for contamination and adding exocet fuel additive .

Take the leak off pipes off your injectors and see if any fuel is coming out of one more than another. Also try andUnplug the plug on the high pressure pump and see what she does then

Thanks for your reply machine is going into dealer in morning will see what the problem is .

You will probably find you will end up with 4 new injectors and pump. Scary money when they are genuine parts!

Just waiting on a set of injectors for a 536/60, £490 each + fitting £500ish already had a fuel pump a while ago iirc £400 + so I’ll not be far away with £3k
