ok if there is no current to the little wire when the key is turned to start, but R6 is clicking, then it is a wiring issue form R6 to the starter solenoid. did you clean the end of the wire before you put it back on the starter? can you trace the wire back to where it originates?
as jay said, check the contacts where the relay plugs in.
maybe the output wire from the relay is crap.
