  The plunger just sits there inside the coil portion with the spring 
pushing it down unless the coil is activated.  Haven't pulled more 
than a couple.  Mine just sits there like that, no snap, retainment 
or anything.  Works fine.  
  Like Mark suggested, make sure if you do or don't have fuel.  You 
already know it ran before so air and timing should still be right if 
you did this in the car.  That just leaves fuel delivery, which you 
had issues with at the beginning.
