Hi, I have circuit diagrams for the injectors if you need them.
if you have 12v on the injectors then the signal from the ecu might be broken. All the injectors are fired together at the same time, check for continuity from pin 12 on the ecu to the injectors. wire colour is grown/yellow at ecu and brown on injectors. if that is ok and you have 12v then best guess is the ecu must be at fault.
Seems strange to me that the RAC bloke got it running by rewiring the 12v feed?
