Hi john, are the injectors switching, do you have a reading for rpm on live data? If these ok Recommend volt drop the live supply to the coil, then carry out a switching test on lt wires at the coil (looking for about 0.3v with the bar graph pulsing) on each wire. If not switching check output back at ECU. If no switching here would ask customer if they were previously driving the vehicle with a misfire...if so may have taken out ECU...
