I have a 2001 chevy Blazer. I have changed the battery and starter because they wer both bad..Since changing the starter every so often It will not nor with it turn over. Its sound like the starter is ingaging makes a sound like its hitting the fly wheel...Any suggestion ??

If the you hear a clicking noise when starting it usually caused by the solenoid attempting to engage, but not getting enough power to do so. You may want to check your battery cables to make sure they're tight. Before doing this disconnect the battery cables make sure the clamps are clean. Check the battery connection to the starter to make sure it's clean and tight. Check the battery connection to ground to make sure the connection's clean and tight. Then reinstall the battery cables. If this doesn't work have the solenoid on your starter checked. Many auto parts will test parts for correct operation free of charge. When a starter with an attached solenoid is changed the solenoid whould be changed at the same time.

I would check all the wires going down to the starter. Make sure it is getting 12V. Make sure your wires on the starter are connected tight and they are none that is loose. The starter may not be contacting the flywheel. You might have a piece missing, causing it to slip. Check your starter solenoid. You could try the ignition fuse, it wouldn't hurt. I would check all the wires first. If it is not getting 12V all the time, it is not going to run right. You might have a loose wire down there somewhere. Mia, check all your connection ends. Make sure all the starter wires are connected. May be one loose. Mia, if you need anything, please let me know. I am here to help. Thanks for choosing FixYa.
