95 2.5 ovreheating when I can keep it running...HELP

With all the good info I've obtained from this site, I'm pretty sure I have a bad waterpump. Off hand does anyone know where to go to get the steel replacement parts? #2 I had no problems till I ran this work or art out of gas. It would start and run what seemed to be the fule in the line out then stall. After changing fuel filter it now won't start at all. The pump runs, I have pressure at the shrader valve. Pressure reg.?:screwy: I haven't even gotten to drive this car more than 6 miles since I bought it last week. It has only 70k miles if anyone wants to know.

Hey thanks for all the feedback guys!
It was the water pump and the other problem was an electrical connector on the coil pack...
