Hi, according to what I have read the code is for the  injector power supply caused by a fault at the injector plug or the wiring, which begs the question when you replaced the offending injector was it second hand/new and did you recode it to the car.

Hi Steve

it was a new injector for number 6 and this has been recoded I have just done a noid test and have no power to injector 2 or 3 so will have to check for the offending connector/ wire or Fuse/ relay 

Can't find the relays except for one in the boot

Hi try inspecting the wiring loom to that injector especially the plug connector to the injector as these are prone to corrosion, please can you quote the DTC number.
