If you can feel R6 clicking then: 1. the start position of the ignition switch is good. 2. R6 is getting the input signal from the ignition switch so the wiring is good.

Just becasue R6 clicks when you turn the key doesn't mean that it is good. Relays can click but the internal switch can be bad. What you need to do now is check out the starter and find the solenoid, like Brapple said, its attached to the starter the solenoid looks like a little round tube with wires going to the back of it. There might be a cover on the back of the solenoid to protect the wires, if there is take it off. Use a voltage meter and check for voltage on the smaller of the wires when your wife turns the key to start. If you see battery voltage then that means that R6 is good and the wiring is good and the starter is bad and needs replacement. If you don't see voltage then R6 is bad and needs to be replaced. If you put the voltage meter on the big wire that comes from the battery, that should also have battery voltage all the time.

You swapped out the fuel pump and the headlight relays and the headlights still worked so the fuel pump relay is good. The next thing to do is get to the fuel pump, its on top of the gas tank, you get to it by removing the rear seat cushion. My Haynes manual says to fold the seat cushion forward and on some models there are mounting bolts that need to be removed. I took the seat out of my SVT when I had it and there were no bolts, just pop-together clips that are a pain to get apart. Under the seat cushion there will be a rubber gromet, take that out and that will expose the fuel pump. Then its time to try what the count says and tap the pump with a soft hammer while your wife turns the key on and see if the pump turns on. It looks like there's some plastic parts on the pump so be careful not to break them.
