I have had similar problems with the EZ Start, one of the prongs got pushed up ito the body of it...to get the dirt out

1. Open and remove battery
2. Get a small flathead screwdriver and push the sides in where you can visibly see the little catrches on the outside of the ez start
3. pull the second shell out of ez start
4. Use whatever technique required to pull the four wires out and push the dirt out
