Are you able to restart?
Does feathering the throttle keep, engine running?

Hi, I have a vitz with a 1 litre engine and it starts o.k but then immediately dies. There is fuel at the rail and as far as the injectors, also I checked and there is power on the injector plugs. It starts again fine but won't continue to idle and eventually dies again. If I keep my foot down on the accelerator it will keep it going but as soon as I change gear it will cut out help? I was told the clutch was a little worn would this be the problem

The idling speed seems to be too low. Have the throttle body and IAC cleaned and retest.
