A bit of an update, when i first measured the fuel pressure with the generic diagnostic tool i seemed to get 500bar which decreased to say 150 bar by the time i stopped cranking it, I tried disconnecting the brown plug on the pump and that gave a steady 1800 bar whilst cranking, i then coneected a fuel supply direct to the pump to eliminate blocked filter leaky lines etc, it seems to be about 350bar constant when cranking, So im believeing the fuel pressure to be ok. (the return pipe from the pump to the tank i just left without having the fuel filter connected, just let the fuel go into a container, the fuel in my pint auxillary container was being pretty much used and collected by the other container whilst cranking for maybe 20 seconds, I'm guessing that about normal as the fuel is continually circulating?)

I've checked the valve timing and all seems ok, The problem is definately the injectors are not firing for whatever reason, All 4 don't fire so i have to assume its not 4 fault injectors as they were fine prior to changing the engine,

All wires and sensors appear ok, Again there appear to be no fault codes, I was thinking of replacing the cam position sensor as they are only £20.

I was wondering if the continual connection and disconnection of the battery could of made an ecu not recognise the key or something? and hence somehow is immobilised? tried both keys no joy,

Begining to wonder what to do next!!

No fault codes are appearing, THe engine management light is staying on whilst cranking (can't remember if it always used to) the glow plug light is not on.

I'm stuck!!
