Don't forget to check the output voltage from the starter relay. When the points in the relay become burnt over time, the output voltage from that relay will be decreased to a point that it won't operate the starter solenoid. One clue to low voltage to the solenoid is burnt contacts inside the solenoid, because the low voltage from the relay doesn't allow for good solid contact because of a weak electro magnet pull. What usually happens as the condition worsens is the solenoid will stick and not disengage. If that ever happens, change the relay and disassemble the solenoid to clean the burnt contacts. There may be other causes for your problem, but this one is easy to check.
