Thanks everyone for your help to date.Originally Posted by More Power
The fuel filter has been changed and there appeared to be no problem with the lift pump when I bleed the air from the filter housing.
I will post the codes as soon as I can have them read.
Also the vehicle had a new Blue label IP fitted about 8 months ago before I puchased it, and they have remotely mounted the FSD to a piece of 3 mm steel plate near the AC compressor.
This vehicle was running fine prior to this problem occurring overnight and was returning 7.5 Kms per Litre on the highway.
Look forward to hearing from you guys again.

I don't like the sound of where and what your FSD is mounted on. Take a look at some of the Kits and heatsinks available and compare. You might want to wait for more appropriate advice but sometimes the stainless steel screws on the FSD loose contact. You might try removing the FSD from the sttel plate and carefully removing the caps off of the two T03 case transistors. Then very carefully loosen and tighten the 4 screws - Not too tight!(2 for each transistor.) Then use some heatsink compund or pad and remount.
After reading all about FSD relocation and another alternative unit, I still believe the FSD to be the way to go and the best place is on the side of the IP where the manufacturer intended it to go.
The problem is that most time the damage occurs after the engine is switched off when the heat builds up in the engine bay. Whilst the engine is running the fuel running through the IP keeps the FSD cool but after the engine stops the heat build up can cause damage. For this reason I can't see a benefit to the Repositioning of the FSD to a Heatsink in the Enginebay except for the ease of replacement when it too fails.
I haven't seen your installation, but I'm not sure I would put a steel plate in the same class as a heatsink.
For the vehicle to have been running fine when you switched it off tends to lead me to think the FSD is worth a thought!

Hi everyone.
Well its not good news but I have managed to get some codes from a dealer although they have little or no knowlege of the vehicle and were hesitant to reveal the codes, here they are:
P0216 Injection Timing Control Circuit
P1214 Injection Pump Timing Offset
Does this in anyway point to the FSD or something else?
Also asked about checking the TDC Offset and the guy was clearly out of his depth.
Oh he also said that the Injection timing was 0.0 when in on mode and 6.8 when in off mode ???
Advice given was anything from a new IP to a new PCM (computer) they just don't know.
Vehicle appears to run fine for a minute or two when it is cold but then massively overfuels at low revs, however seems to run normally over 2000 RPM.
Any help would be appreciated.
Have a search of the forum for "P1214". There are some recent similar posts that may help. Would be a good Idea to get Actual readings before making any adjustments. eg Top Dead Centre Desired, Top Dead Centre Actual, and Top Dead Centre Offset. Remember to score a mark on the pump and timing cover so you can reverse any adjustments.
If you are technically minded you may want to purchase your own Scanner, I recently purchased a cable from the states to interface OBD II socket with a laptop. Didn't break the bank either!
Cheers

Can anyone suggest where to enquire and how much?
