Okay I have had this problem for quite a long time I have gone through about 4 starters which all quit engaging with the flywheel. What happens is when I am crainking it over ususally when it is hot, the starter like kicks back, its weird I have never heard a vehicle do this before. When it kicks back I just let of of the ignition switch and start over sometimes it will do this 2 or 3 times before it starts when it is hot. 4 starters later I remember a tech telling that the flywheel has a notch in it that indicates TDC to the CPS and that it might be scratched or dirty. I have gone through four starters all which last about 6-7 months before they stop engaging with the flywheel. Grrrrrr... Anyone have any suggestions I really want to get this fixed once and for all. Thank you in advance for any help you may have.
