Right got home from work early and tested radio suppression relay this is working fine and delivering 12V to the injectors when the ignition is switched on this made me think the issue is with the ground switched supply from the ecu. To prove this theory I bared a little of the wire to one injector and bridged a wire to the negative terminal of the battery, the car sprung into life and sounded the best it has for ages clearly this isn’t a fix but it’s progress any suggestions where to go next?
