Your description is really hard to understand. I CAN tell you there needs to be a spacer on the end of the crankshaft position sensor to set the critical air gap. If you install a used sensor without the spacer, chances are you will push it in too far and it will be broken by the rotating flex plate. Chrysler sensors come with a thick paper spacer stuck to the end. They slide off the first time the engine is started. Some aftermarket sensors come with a thin plastic rib molded to the end. When reinstalling a used one like that you're supposed to cut the remaining part of the rib off and use a new paper spacer.
