Hi I’ve checked my relay and wiring and everything is ok apart from 86 which is the trigger for ecu to prime the pump , when I put a probe on 86 it’s live 12 volts , then when I put a earth to it , it will trigger the pump , so obviously the blue/white ant switching it to earth . Theres power to the ecu , is there anything else that could effect my blue /white wire to trigger ? ? I have no spark either so I think ecu is cooked ! Is there anyone local to Milton Keynes /dunstable/ to plug in to see if broke (will give u a drink)before send it away to omex or is there other specialist that can work on these ? Many thanks
