I unplugged the wire to the fuel solenoid and immediately got "Err 02" on the EIC with the ignition in the "on" position. Plugged it back in and started the machine, at 2 min idle time the machine shut down and again displayed "Err 02". Next I put the service switch into "service" and the EIC emitted a long beep and displayed "Err 02" as soon as I turned the ignition to "on". Thanks for the suggestions I've already received.
