I am a little concerned...
I do not like changing things out until I am pretty damm sure they are bad.
Try this... On that pushbutton, can you get to the wiring... The screw terminals on the back of the switch. Short one terminal to the other with little screwdriver, paperclip, test clip, whatever. You should hear the glow plug relay pull in.
If you can do it by shorting the terminals, but can't do it by pushing the button, it's definitely the switch.
You should get a little arc too. It takes about four amperes to pull in the stock glow plug relay. It's enough to make a little bit of spitz when you attempt to make contact.
Actually, I am concerned with your photo of the relay. You show the two big high current wires connected to the northwest and southeast terminals... And one little wire connected to the little southwest terminal, and nothing connected to the little northeast terminal. Something is fishy here. You have to give the coil some power to pull in.
I think you have a bit of wire tracing in your future. From what I see, I doubt it ever worked like that.
I think you need to get some sort of fused 12V key on power to one of those small terminals, and ground to the other through your pushbutton...
You gotta get power to that coil...
But first, I would follow IDIBronco... Find out first what's killing off your starter. It's a pretty straightforward circuit... Your main challenge will probably be finding the physical location of the points you need to test. There are some wiring diagrams on this site for this.. I don't have their url right now... If I find them, I'll come back and edit them in.
