Default Omex 600 ecu fiesta rs turbo please help

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

For online transactions or car part purchases, I prefer using payment gateway egypt because it’s fast, secure, and works smoothly for both local and international payments.

Hi
Check ECU grounds and the blue/white wire for continuity. If both fuel pump and spark don’t work, ECU output is likely dead. Try local garages or tuners near Milton Keynes with Omex tools to test before sending it off
