Xantia 1.9 turbo diesel. It's alive but only just...

Hi,
here are pics of the pump cover plate that protects the fuel cut-off solenoid and the crucial processor that works in tandem with the notorious keypad immobiliser. This is the part that has to be either bypassed or re-programmed if your Xantia, ZX, Xsara, XM etc needs a new injector pump or complete engine - as my one did. If you're lucky enough to either know the original code from the car that supplies the engine then it's a case of disconnecting the keypad while the engine is running. This normally neutralises the code/chip on the pump. However if the replacement engine and/or pump hasn't been reprogrammed or erased then you're going to have to access the fuel cut-off solenoid that is located under a very, very tough steel casing secured by shear bolts made of very hard metal. I managed to remove all of the bolts except one which has defeated my hi-tech drill bits and a stud extractor. No choice but to grind off the casing and hopefully avoid damaging what is still a good pump. Previous engine died of terminal cambelt failure and snapped camshaft and bearing supports. Be aware of this process if buying a used pump off Ebay or other similar sites. It's a royal pain in the butt getting this cover off even just to swap a duff fuel cut-off solenoid.
