would appreciate any thoughts anybody has on this. when i turn the key the starter won't catch, i just get this buzzing noise. once it's started it runs good, it's just first thing in the morning. the starter is only about a year and a half old. I did just replace a plug wire, it was totally corroded but that didn't seem to help. I was wondering if it could be the igniter or some other god-awful expensive fix. the plug wires aren't that old either, nor the distributor cap. help please...https://www.rx7club.com/newthread.php
