I finally figure out how to troubleshoot my ignition problem and now it won't misbehave. 1989 5.7 Alpha One just clicks when turn the start switch when it's cold, every time. After 3-4 tries, the starter will engage. So I let it sit for a few days and get my test light hooked up to see if I have voltage at the starter solenoid when the switch is in start position, AND THE STARTER ENGAGES! This is making me crazy. When you want it to break, it works. When you want it to work, it breaks.
