Vehicle recovered,just packed up while driving. Garage found loss of HT and spoke to Mazda, they suggested replacing the 2x coil packs, as they said can cause trouble.They fitted new coils and also a new crank sensor still no spark ?. Had a look and did some tests, on cranking there is a spark but only there for a couple of seconds then nothing, the injection pulse doesnt seem to be affected,checked that the cam signal was working. Had the ecu sent away for testing, came back all ok!.Did try cranking it with the immobiliser plug removed, which shut down the injection. No engine fault codes shown. Need an ecu circuit diagram now if anyone can help or have any ideas what could be causing the loss of HT.(tried Bosch & Autodata)
