The vehicle computer commands the ignition coil to fire the spark to the plug at a specific time. The crankshaft pulley has a mark located at tdc (top dead center) position of cylinder #1 only , so you must use the cyl. #1 plug wire in order to accurately view the mark on the crankshaft pulley and the block.

Apply parking brake. Warm up engine to normal operating temperature. Turn OFF all electrical loads. Connect timing light to number one spark plug wire.

Remove the inspection plug and connect the inductive pick-up of your tachometer or timing light to the number one (1) spark plug wire. If your tachometer/timing light inductive pick-up is too large, the coil cover will have to be removed. Verify that ignition timing marks on crankshaft pulley and timing mark on timing belt cover are aligned. Ignition Timing: BTDC 8
