so u've got the leads on as per the pic, and yours is a rear facing cap, not a vertical 4x4 one...?


there should be 4 small lugs on the bottom pulley, equally spaced around it and the gap between the lug top and the sensor face shouoldbe 0.6mm

first i'd try unpluggin it though and squart some carb cleaner inside both connectors, make sure its clean..
