Post Starter Problem

I just replaced my OEM starter motor in my camaro because the solenoid had gone bad and would not move the motor when I turned the key. I just installed the new one, made by CSI (P/N: CSI-100u), wires are all connected properly and when the key is turned the motor starts cranking the engine. However the engine wont turn over and the starter stays engaged to the flywheel. I've tried to lower the starter by placing three(3) 0.005" spacers between the block and the starter. Any ideas on why the starter wont disengage and the engine wont turn over?

take the serpentine belt loose and try it again, if the engine turns you will find that you have a bad alternator(locked up), this is why the engine won't turn over.

Is the ring gear ok? Might need to go a little more with the shims.

All the gears are fine, Ill try more spacers... Going to have to fab. these though
I was reading some of the other starter problem posts and I wanted to add on a side note that there is no grinding noise and the starter has no problem engaging the flexplate. And I've tried the starter when its not bolted up, extends and retracts like it should.

Check the number of teeth on the pinion of your new starter, had an RX7 once that in mid year they changed the number of teeth from 7 to 9 on the pinion.

Worth a look.

hmm... might have something there... Not sure if the '86 camaro came with a 153 or 168 tooth flexplate, but this new starter is supposed to work with both. Although the OE starter is a 9 pinion and the new one is a 10 pinion...
(counted 3 times to make sure on each)

Can you turn the engine over by hand or with a socket on the crank bolt? Does the shape and pattern of the starter gear teeth match the flywheel teeth? Just a few thoughts...

arch, in your original post you said when the key is turned the motor starts cranking the engine, however the engine won't turn over. have you checked your battery voltage, to see if it has enough power to turn it over. have you turned the engine by hand. do not use all those shims, if that thing turns over or starts it will probably break something. at the most, you should only need one or two shims.

Since you say that the starter motor "Turns and Turns" but the engine isn't turning; then the starter is NOT engaging the ring gear on the flexplate (Flywheel). From what you say above, you have way too many shims. If the starter mounting bolts are the staggered pattern you do NOT use any shims at all. If you need shims with that bolt pattern then the nose support is incorrect on the starter.

One question that several folks here have asked you is whether or not the engine can be turned over at all. Disconnect the battery for safety reasons. Remove the spark plugs. Place a wrench on the harmonic balancer bolt and turn the engine over (Clockwise looking from the front of the engine) If you can not turn the engine over this way at least two full revolutions, you have internal engine damage and trying to get it to turn over with the starter motor is fruitless. If you are able to turn the engine over at least two revolutions, then remove the wrench, re-install the sparkplugs and the starter motor. Remove the starter solenoid and manually pull back the lever to extend the starter motor drive gear until it is fully extended. This is the position you need to have it to check for the proper engagement and clearances with the ring gear on the flexplate (Flywheel). You should be able to slip a straightened out paper clip between the top of the tooth on the starter motor gear and the base diameter of the ring gear. Good luck!!

I asked about the bracket because if it isn't thear the starter can get angled and hang, or eat up the flywheel. you can get the bracket from the dealer for about $7.00.
