Ken,
Just what do you mean by this ?
As stated in my case: The fuel was cut off by a voltage transient
induced into the injection ECU caused by an intermitent break down of
the ignition coil to the 12 volts supplying the injection ECU. After the
motor quit running, there was still perfect spark supplied but no fuel
to the injectors.
After waiting for about an hour, the injection ECU would reset and
supply pulse to the injectors again.
