    Vehicle was parked up night before, next morning no start. Switch on ignition no check engine light or fuel gauge,no power to gas system.
    If main relay is powered up gas system powers up and i have power to ecu, but no check engine light or fuel gauge,Can get comms with ecu but no codes.Pinned out wiring from ecu to dash all ok.
    Pinned out wiring from ecu to main relay ok.
    Checked ecu earths ok.Remove ecu and fit to another jeep, check engine light and fuel gauge
    work ok.
    Suspect the ecu is seeing something it is not liking and shutting down the system.Is this possible?
