How to increase reliability on a Ford 300 inline 6?

I know people say the Ford Inline 6 is pretty much bullet proof. I have one with 212k Miles and looking to rebuild it when I get some cash. Would Forged internals increase Reliability or just power.

Now, if someone can give me a answer that'll make it more reliable and more power, well that's even better.

What's the problem here, with the A/C and the idling engine?

2000 Ford Contour SE.
1. A/c blows the air out from the defrost vents by the windshield instead of the vents on the panel…

2. When I'm stopped at a red light with car idling, the car starts vibrating as if it wants to shut off. I was told the problem was a sensor that's connected to the engine that keeps the engine revved at a steady pace while it's idle. Is that true?

What is the better first car?

I'm getting my license this fall and have boiled my list of potential first cars down to two models. The first is a (used) Ford Crown Victoria Police interceptor, and the other being a 1998 Subaru Impreza RS (Outback sport is fine too). I have done the research on both models regarding insurance, reliability, and whatnot, but am really torn on what the wiser investment would be regarding the two. (Please no alternative answers like "just get a Honda Civic", I just want to know which one of these is a better choice).

Why is there no power at the fuel pump on my 1986 ford e350 jamboree?

I have a 1986 ford econoline 350 jamboree motorhome. It has a 460 v8 gas motor. The fuel pump isn't working. I checked with a test light and there's no power going to the pump. I checked the inertia switch under the dash and hit the reset button and used my test light on that and there's power going in and out of it, i used to my test light on the oil pressure switch and there's power going to that. The camper won't start and was having problems with vapor lock. I checked all the fuses and tried tracing the wire from the fuel pump but i'm not sure where it goes. I did have mice in the camper that could have chewed the wire but i would need a wiring diagram for my camper. If anyone has a wiring diagram of the fuel pump on my camper i would appreciate it. Would replacing the fuel pump fix the problem? I had the switch on when i checked all the wires with my test light.

Added (1). it has a carburetor, no fuel injection
