C5 2.2HDi Executive '02 plate I have a very strange intermitant problem with this car, for no apparent reason it will just cut out while driving, it does not go into limp mode, the engine just stops dead and will then not restart untill the key fob has been pressed several times. When the engine won't start I have found the following. Fuel filter bowl full of fuel No fuel feed from low pressure pump Injectors not firring Lots of fuel presure at injectors Having pressed the key fob several times the feed from the low pressure pump will come back and the car will start and run untill the fault happens again (could be a couple of mins or a couple of hours). I'm convinced this is an immobiliser fault (I don't get any faults on the LCD) but I don't have a clue where to go from here. I have had 2 diagnostic checks done, the first by the RAC came back as low battery voltage even though the battery metered at 13.6v. The second by a local Citroen garage who said it was the high pressure pump at fault, having checked the output from the pump I think we can rule this out. Is there any way I can bypass the immobiliser??
