    My gti randomly wont start. Wait 5 minutes then it will start then may cut out while driving then starts again.

    Anyway I took the fuel pipe off at the rail and had fuel under pressure squirt out.
    Turned the ignition on, no fuel from pipe, cranked engine, again no fuel.
    Waited a couple of minutes tried again then had a squirt of fuel with the ignition on then cranked it and had lots of fuel. Reconnected the pipe, engine starts.

    Now it's not starting again. Prior to this I thought the pump was sounding noisier than usual.

    I'm presuming the fuel pump is at fault here but is there anything else it could be?

    Should note, when this fault first happened a few weeks back I changed the coil and crank sensor as a precaution as it's my mrs car)
