    I noticed it in the video pal. Fuel pump relay are usually a culprit.

    Would the sfi not being on make it run so lumpy?
    Hoping that's what it is and not the timing haha.

    I've ordered a relay picking up up this afternoon

    Yes as the air flow meter readings will be all over the place.

    So I've fit the sfi box tried new relay and nothing still no power to the pump.
    Tested continuity from the red/blue on the plug in the bay to red/blue at the pump and that's fine, test between red/blue at relay and blue at plug and nothing, tested blue at relay and blue at plug and fine. So it's either something in the loom or the ecu isn't telling the pump to come on I'm not sure.

    So I wired up the pump to an ignition live and started her up and she runs like a dream, all be it sounding rough cause no exhaust haha.

    So what I'm thinking is I have a spare ignition live in the bay, so if I connect this up to the red/blue going to the pump it should work fine.

    Video of it running

    What I've done is connected a spare ignition live I had on the loom to the fuel pump red/blue and I now have power to the pump on the ignition and car starts and runs fine.......so that's how it's staying

    I've also fit my slimline fan
    Just putting all the interior back together

    Preferable to keep the fuel relay so it not still pushing fuel when the engine cuts out. Can't tell if you've bypassed it with that wiring.
