good advice, and I sure hope it helps!
I'm have to go out on a limb though, and say that I think it's something different.
it just seems too consistent in it's nature to be a connection, and the description of the problem is off IMO.
I would suspect a solenoid to act like this, where it will click only, but not even attempt to turn over.
I would suspect a loose connection to be a little less consistent. (again, just my opinion here...)
now, I have to admit that the problem sounds like no other starting problem I've seen, so,.....I'm wondering if it could be the key?
