starter problems?

every once and a while when i try to start my car it just dosent. when my key is in the on position all the dash lites up like it normally would but everyonce and a while when i turn the key to start the car all the dash just goes black and it wont start even though you can hear the starter spinning around. Ive replace the battery, altinator and starter. Im all out of ideas.

Have u checked to see if maybe a short is draining ur battery? Cuz other than that and what u have replaced theres not much to the ignition system. I guess u could check ur plugs, cap, etc. Don't replace yet though. I picked up a spark plug checker at a store for 2.99$ and it plugs in where the spark plug should go and blinks constantly if working correctly. Ok so basically the only others things that could have a problm other than what u fixed already are these things. Ignition coil[test with an ohmmeter], Ignition wires, plugs, distributor, rotor[ look at distributor cap and rotor to check for damage], Check ur fuses[ Do this first], and ur regulator. Good luck and let me know what happens!:evillol:

before you go out and buy a new starter, and run a full diagnostic, why don't you check out the switch that checks to make sure your clutching when starting. I *think* its called the neutral safety switch, and it costs like $33. ***IF*** it is broken, you can replace it....or bridge the circuit like some of my friends have done (lets you turn the car on without clutchin')
