    My starter got messed up the other day, but i messed with the connections on it, and got it to work for a few days. This morning in a parking lot, the same thing happened, no turning over, etc. My fingers were numb, so I took the trailer hitch off the reciever and smacked the starter a few times with it, and it worked for about two starts. Now I have a hammer with me, and use it every other time I start it. What could be wrong with it? Do i just need a new starter? How much are they, and how hard to put on? Thanks

    New starter. Pretty easy to replace. Two bolts to the block (do NOT overtighten them when putting back on, you will break the block) and two for the starter wires. Might as well get one with solenoid. I have never really had much problems with aftermarket starters, however, I do not run headers which tend to run close to the starter and burn them up quicker, besides making the starter harder to remove (in some cases) You can get them from GM also. I think the last aftermarket starter I bought (rebuilt GM unit which probably 99% are) from a chain store, with life warranty and a solenoid, was $50 or $60. Worth changing every two years for the price if you ask me. IF they fail that often, which hasn't been my experience with the aftermarket units.

    Sounds like you got a bad spot in the brushes, take the other posts advice and get a new one.

    If you were able to get it to start the first time by messing with the connections you might want to stop beating on it. I'd go back and find out what's wrong with the connections. Just might save the cost of a starter--if it's not too late. Just a thought from the peanut gallery.

    Probably the starter solenoid. Just replace the starter. I got my last one for about 30 bucks at Advance Auto. As long as you turn your old one in for the core charge they are cheap. Good luck.

    When all else fails... Check the blinker fluid.

    i remember i had an oldsmobile a long time ago. for about the last 2 years i had it, banging on the starter was a frequent pastime. then suddenly the problem went away and i sold it.

    I just finished replacing it. Starts like a charm now, except it makes a wierd noise right before it catches. Does this have anything to do with those shims i keep hearing about?

    The noise is not really wierd, just higher than before. i asked a mechanic today and he said its nothing to worry about, i probably just a have a high torque starter.

    Shouldn't makje any weird noises, however if its not teeth grinding, gues I wouldn't worry too much, especially if its lifetime warranty. Were there shims when you pulled it? If so, those are supposed to be re-used when you replace the starter.

    One question I have, is why re-use the shims? Yes, the block is a constant. The nose of the starter, when replaced, is not. To me, if anything, when replacing a starter, the original nose cone should be swapped to the new starter to prevent a problem. I have no clue how GM measured for a shim, seems odd to me with manufacturing tolerances being what they are between the block and the starter nose cones, that it would be pretty near impossible. On top of that, with the way the starter operates, where would you take a measurement, since the angle of the gear on the starter is what hurts the ring gear, not necessarily the nose cone to block itself.....

    Dorian, you need to take the measurement between the flywheel ring gear and the starter gear. You have to manually extend the starter gear to take the measurement. The shims that were installed at the factory may or may not work with a different starter due to manufacturing tolerances on both the block and the starter. The correct procedure is documented in most good service manuals. Many times, you can get away without going through all the steps and just bolting the starter on. But I've had starters that hit the ring gear instead of turning over the engine until I installed some shims and measured things. [​IMG]

    Ok thanks Harry, wasn't sure if GM actually went to the trouble to measure all of them like that, or if they had some other way (like fire it up and see if it grinds hehe)
