    What problems do I need to look for? How much would I new starter cost? It only does it every now and then, it usually turns right over and fires right up.

    Mine was a rare condition.... the bolts on the flywheel backed out. It took out the flywheel, starter, and tranny. Good thing I was about to replace the engine. It turned out I replaced the tranny while I was at it.

    The common problem is that it will eat up the teeth on the flywheel if your starter doesn't line up correctly. Then you're in for replacing the flywheel and the starter. Its definitely worth your time to get under it and look around.

    look around for what? take the starter off and look at its teeth? Could my flywheel be warped in some place? I imagine replacing the flywheel would be a PIA.

    I almost feel like I am talking to myself, but maybe a few people will respond. After reading a bunch of previous threads, I have decided to try a starter shim kit. I feel like this is almost grasping around in the dark, but maybe I will get lucky and solve the problem........ it this a good idea......... anybody???

    proll mix of blazer fest and friday :D i have no life so my guess is ...
    see if bolts are loose
    take starter off and look at the teeth - starter and fly.
    check to make shure the starter isnt binding or not releasing after the thing starts.
    dust cover clearence.
    if u still havent found anything put it back to gether (use some locktite) and see if it does it again. sometime she just wants u to kiss the boboo and it is all better(mine does anyway).
    if it does it again well go in to more complicated stuff :wink1:
    ive never had to shim mien-its a ford thing id try this stff 1st then see. ull be able to tell if that is the prob after u take it apart- or take a pic and we will tell u :D
    oh and what are ure specs(engine,tranny,year,ect...)

    Crawl under there and make sure the starter is bolted down tight. If it is loose, it sounds like this until the bolts break off and the starter falls down, arcs out on the axle and fries your electrical system. Sometimes the first thing to do is look at the problem and see if anything is obviously wrong. :doah:

    Take off your flywheel cover (dust cover) and there the flywheel appear's! Then you can check it all out.

    Rusty, thanks for the link. Chaddy, how do I get the flywheel dust cover off and what does it look like? is it the black cover thing that is held onto my starter with a large phillips head screw????????? sorry for my ignorance, but I've never fooled with a starter.

    S'io credesse che mia risposta fosse
    A persona che mai tornasse al mondo,
    Questa fiamma staria senza piu scosse.
    Ma perciocche giammai di questo fondo
    Non torno vivo alcun, s'i'odo il vero,
    Senza tema d'infamia ti rispondo.
