This is most likely a fault with the cylinder position sensor. The No 1 plug is able to fire because the TDC sensor (which is set at cylinder 1) is working and providing the conditions for the spark to occur then. Have the CKP sensor tested. You should have the Check Engine Light on with trouble codes stored in ECU.
