Hi, Thanks for input.
@ C.I.M - If you read further back in the thread, the initial fault was on cylinder 1 (car wouldn't even start as cylinder was completely dead) and all the packs were isolated and checked. Since the injector harness has been put on the fault has moved (although it is possible there were multiple faults to begin with but cylinder one was so apparent, that they got missed as no codes were read.) The injectors have been isolated, all sparks are new, coil packs are ok.... so surely it has to be electrical?? I'm no mechanic but could a blocked cat cause multiple misfires? What pulls me away from this, is the fact that there is no signal to Injector 3 so it must be the injector harness? Am I missing something???
