    Unhappy D3 AJV8 no start

    Hoping the brains trust can point me in the right direction before I start dropping cash.

    My Disco had just come back from a frosty weekend in North Vic, about 600km return, with no apparent issues.
    I tried to startup to do a shop run yesterday and I get no ignition.
    - The starter is running and turning the engine over.
    - I have working spark.
    - Battery is sitting at 12.2v ign (as it always has been since I bought last year).
    - Seems I have no fuel pressure/pump as when it is in startup the fuel rail valve does not release anything.
    - The fuel relay is getting 12v in, but when I bypass I cannot hear the pump.
    - The interlock and immobiliser looks to be acting as normal.
    - The dash is now reporting check brake pads, which it wasn't when I was running on the weekend.
    - I am somewhat confident that the pads are fine, but surely that shouldn't stop ignition?
    - All fuses in the engine bay are fine, I cannot get to the passenger seat box as it is parked inside with no access to passenger side.

    Is there anything I could be missing before I go about dropping a half full fuel tank to manually test the pump?

    Do you have a fuel filter in the line or is there a kink in the line

    No kink or blocked filter in the way. The fuel pump was not engaging at all, even with the relay bridged.

    I have ended up spending the arvo dropping and draining the tank. A painful process to be sure.

    I have found the pump works fine on my 12v bench supply. I did find that the body loom was showing 12v, but would immediately drop to 0.001 when connected to the pump. So I rigged up a bypass to the battery to test the main loom. Sure enough, there is a high resistance negative as the positive from the loom and the negative bypass runs the pump just fine.

    Think I will splice out the negative and route it to the body for now, instead on chasing negative up above the diff. I don't have time in the next week or so to do that haha.
