    Fuel pump woes

    What would stop my fuel pump getting 12 volts?
    Car is broke down now at the minute.
    Was running poorly about 2/3 of the power now it's not running at all.
    I swapped the fuel pump just to try another one but that's not working either.
    Lost this came from nowhere.

    Still won't start with the fuel pump running
    Airlocked? Even so have just jumping at the relay to get the fuel pump to cycle. Swapped with the relay that's the same no joy ;'(

    No alarm not affecting it. Will cycle when I jump the pins at the relay.

    Would throttle position sensor cause this? One of my sensors has always been fairly noisy.

    Nope shouldn't do. Here's a stupid question but is there any fuel in it?

    Also do you have a spark?

    I put a new varta battery in it about 3 months ago. Cranked it all day sunday no problem. It was driving at really low power rather than just totally going that why I originally thought fuel pump but it isn't that.
