antony lacey Posted October 26, 2022 Share Posted October 26, 2022 Evening guys hopefully someone can help! So car has been running fine , not used it for 2 weeks ....go to start and it's runs for 2 seconds then cuts out. Tried again with a bit of accelerator..cuts out again. After searching here, I bridge the relevant ports on the diagnostic to run the fuel pump and it starts and runs fine. Changed the efi main, still cuts out Possibly fuel pump ecu ? Brought a tested unit and no change. Any help would be much appreciated on what to try next Thanks Antony Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted October 26, 2022 Share Posted October 26, 2022 Sounds like fuel pump ECU or signal wiring to it is having an issue. is this a completely oem setup or any modifications? Quote Link to comment Share on other sites More sharing options...

antony lacey Posted January 6, 2023 Author Share Posted January 6, 2023 Evening chaps Thought I'd update as finally sorted! After replacing my fuel pump ecu and no change in the issue, I got a auto electrician in .... after a few hours of testing and head scratching, he couldn't solve the issue, he said everything looked in great condition and couldn't understand it . After sulking for a few weeks ( months) Somewhere I had seen similar issues leading to the main ecu, so that been my next check ......this is what I found I tried to find someone local ish to repair it but finally with the help and advice from keron, a replacement unit was found!! And everything runs sweet Massive thanks to Keron, always has time to give advice and help out Quote Link to comment Share on other sites More sharing options...
