    This car runs from cold for about 6 to 8 minutes then cuts out.
    cause of cut out is the fuel pump relay losing its ground, if relay bridged out it runs perfectly
    only code read with tech 2 was:

    P0230 fuel pump relay high value/ poor contact

    fuel level sender reading on live data is 17.9v when running, can this have an effect on pump relay curcuit?

    Checking back to pin 23 of the lower plug on ecu,i seem to have a varying voltage of between 0.20 to 1.3v. this seems very high to me?

    im thinking ecu problem but cant find anyone to test it, any suggestions or am i barking up the wrong tree?

    thanks
    Ed
