Hello:

I have gotten excellent advice here before. So here I go again!

I drove the car to the store. Everything working perfectly. I get back
in it and the door beep slowly died and now the car won't start. It
won't turn over, no indicator lights, no beeps. Totally dead.

A kind stranger offered to jump it and it started right up. Drove home
(thank god) and once turned off, it won't start again.

I searched around under the hood and noticed one of the spark plug
wires (the one with a gold dot on it) was loose. I pulled it out and
the metal shield inside it fell off. I put that back on, but still
nothing. It will always start with a jump though.

I'm sure this is an easy one. Any advice?

Thanks in advance. If I figure it out first, I'll post a follow up.
