Hi guys new here to this community and need help fast please
Just got a 2018 Mazda 3 and it came with only one key fob that was broken to bits and naturally missing the actual chip so I had it rekeyed yesterday only to find it still wouldn’t start. Upon further inspection both the fuel pump and starter relays were missing…replaced them both and still having the same problem. I’m thinking maybe I need to reset the ECU? What’s the reset sequence on this year? I can’t find anything online for this specific year on the ECU reset sequence. Please help!? Also worth mentioning my brother is who acquired the relays so I’m not super confident he got the correct ones.
