Hold key to start position -find the black and white wire at the starter solenoid look for power-power there tap the starter if it kicks over-the starter is bad-if no power. Find the clutch interlock switch at the kick panel on the connector you will see a brown and white and a plain black jump this two together and attempt ot start-if it starts the switch is bad.
