So you think the HPFP has just packed in and the fact thst you were working on the fuel sysrem was purely a coincidence? I'm playing devils advocate here, but good luck with that one!!yµ (idµ - eAµ) ψ=mψ

Actually, come to think of it another member had a very similar issue a while back. Stripped wiring for tests and all sorts. In the end it was the plug on the MAP sensor which had come off! So check all the connections in the engine bay yµ (idµ - eAµ) ψ=mψ

I wasn't thinking of the HPFP sensor, whilst trying to work out what has gone wrong and searching online I came across a blog saying
'What causes the P0088 code?
Kinked or restricted fuel supply line
What are the symptoms of the P0088 code?
P0088 will always have a Check Engine Light accompanied with it
The vehicle is put into failsafe mode to prevent damage to the vehicle
I am wondering if I have inadvertently trapped a hose???
planning to go and drop the tank again to check this afternoon.....

Further information on the blog mentioned....
Common mistakes when diagnosing the P0088 code
Replacing components without testing them is the most common mistake made during P0088 diagnostic.
Step by step diagnosis is the easiest way for foolproof answers, not doing so leads to repairs that do not fix the faults and wasted time, effort, and money.
P0088 is commonly caused by a kinked fuel line, this is usually due to something hitting the line. The only way to see this is to perform a thorough visual inspection.

before you go any further with that forum see the fuel diagram of the D£, that will give you a better understanding of the location of the components and what you are looking for. keep in mind that the TDV6 has a low pressure side and a high pressure side.

I understand that, my logic is purely based on the fact that it ran fine until I dropped it yesterday to sort the float level, as soon as I started it back up again it played up and through up the fault codes, my initial thought were that I had somehow done something to the suspension but I have checked what I can there and nothing is showing up as faulty.
Where is the D3 Diagram you are referring to?

So tank was dropped again and no obvious issues with pipes etc so that's ruled that out.
Working on the HPFP sensor, how do I tell If that is faulty or not?

Personally never had one fail, whenever there was an issue it was always the connector either fouled or not plugged in correctly. Check everything else while you're in there!yµ (idµ - eAµ) ψ=mψ

I have disconnected the connector to the sensor, just going to clean it all up with contact cleaner to see if that helps.
One thing that I did notice is when disconnected the faults are on as soon as I start the car up, before that they took about 10 seconds to come on, don't know if there is anything in that or not?

Can I ask what was the original fault which led to changing the height sensors?yµ (idµ - eAµ) ψ=mψ

The car was dropping and I had it scanned, originally it was one sensor showing faulty then another went after a few days, it sorted it and the car went fine until the LPFP failed, sorted that and now weeks later we have this issue after I dropped the tank to sort the float level as it was not fitted back in correctly so not reading correctly.
