O.K.- After a week of disaaembly and reasembly twice and checking the whole circuit for the fuel pump and alll the window/door lock/seat controls, I found power at the relay, power to the inertia switch, but no power at the pump and still now windows/doors/interior lights, I retraced all my steps from the beginning. As I was wiggling wires under the dash, I saw the main dashboard connector on the drivers side and decided to wiggle that, as soon as I touched the screw on top that hold it together, I noticed it was very loose - I never even touched this when I was working on the truck, but as soon as I started to tighten it, all lights came on and now everything works! I had a feeling it was a connector, as the systems that didn't work are unrelated (so I thought), but as I said I checked everything I disconnected, but obviously the truck had been worked on previously and this connector was never tightened and all the wiggling on the passenger side when working on the heater core disconnected it enough to not work. Anyway - my wife is a happy camper to have her truck back and I am so relived to have found the problem - thanks for the help.
