Ford F-150 4WD conversion?

I have a 2010 F-150 Fx2 Sport model. If you take price completely out of the equation, except if it would cost buying a new truck, is it actually possible to have someone change and upgrade it to that of an Fx4 and give it a 4x4 option?

1987 ford f-150 fuel pump problem?

I have an old 1987 Ford F-150 with what i believe is an on frame fuel pump that doesn't work, now what led me to believe its the pump is that when i first try to start it, it ran for about 3 seconds then it quit. I then turn the key on and had a friend listen to see if the fuel pump in both tanks turn on and which they did but then he listened for the on frame pump and that didn't turn on. I don't believe its the relay in the engine bay cause wouldn't that send power to all 3 pumps, i haven't check the inertia switch or the fuel filter canister. Could i hook up a voltage meter pump wiring to check to see if its getting power? I almost forgot to mention earlier but before it ran fine, had no problem with anything but then one day its like the pump died right away. Wouldn't a fuel pump give any sign that its going out cause that what it did on my other pickup

Truck won't start but its not battery?

My truck won't start, but its not the battery. Thought maybe it could be the start. Only had the starter for three years. When hooked up it won't turn over but when I connect I use jumper cables and use the fire wall trick and battery trick it stars, but not that loud or powerful. Could it still be the starter? The truck is a 1994 ford f150. I know its not battery because everything is coming on, check the all lights and they are perfectly fine.

I'm not sure if this pertains but tried jumping a lawn mower and then about 20 minutes later truck only started when it wanted too, then stopped coming on.
