simon, i have an update...
pin 20 is only getting 8v!
i fed a feed direct from the battery to the pin, voltage 12.18v started the car and
she burst in to life
so that narrows it down to that

cheers all
now... why is the ECU feed low on voltage?
where does it feed to?
its a blue cable with a yellow stripe
RE: the pump.. will it hurt it to run continuoulsy on the ignition? obvioulsy i wont be leaving it on ign for any length of time
