My 2001 dodge ram began making a clicking sound then overheated. As I pulling to the side it shuts off. I restarted and pulled to a gas station, then shut it off. It would not start again. It also lots of water leaking from a tube thru my firewall behind the reciever tank

Firstly, this is assuming that this is a 5.2 or 3.9 engine. The newer 4.7 modle would be totally different.
Sounds like a intake gasket issue(#3) intake gaskets and a belly pan gasket were quite common place one these modles.
(#2) The passing gear or kickdown is adjustable at the throttle body
(#1) This sound is quite likely normal for this truck. Have heard of many trucks sounding the same and at the time it was normal.

First, try a new accelerator pump. They're less than $10 and easy to install. On the side of the carburator, near the linkage. It's simple a small rubber diaphragm.

I hear an answer to this problem was that the overflow tube was blocked.
