Back again with a Click, No Crank condition. Seems like there are a million posts re: it, and I've posted about a quarter of them.
I've been working around it for about two years now and replaced everything but the ECM in so doing.
Today had the condition a few times in the morning and just now, but got it start.

One thing I've always noticed is that as soon as it clicks but does not crank the interior buzzer alarm stops. I've always thought this might be a clue to sourcing the problem cause. Anybody know anything about it?

 

What are you driving? Do you lose all electric power when this happens? Does the radio forget its memory?

I don't have a stock radio. And I don't think I have any presets on the one I've got in there.
Only the buzzer going off is what I notice. I still have cab light, dash lights, etc.

 

Key buzzer is just a little switch in the ignition lock cylinder.... Not sure if that is a separate problem or not.... You *may* have an ignition switch on its way out..... but, that is just one possibility.
