Help! no start

I removed all the "other fixes" once the new starter/solenoid was installed about 10,000 miles/five years ago, and I've had no problems since. I initially encountered the no-start at about 21,000 miles. I am sure Marc would provide the details re the solenoid if asked.

BINGO - best to isolate the problem before throwing parts at it.
Starter, starter solenoid, clutch safety switch are all possibles. A clamp-on DC ammeter can be used to measure the starter solenoid current at the clutch safety switch - there should be about (roundhouse guess) 10 to 20 amps and the solenoid should click in. If not, the solenoid may be heat-soaked and locked open = no current to the starter. Wait for a few hours to cool down and try again - if the solenoid operates and no starter action, the starter needs to be rebuilt. Pretty simple ...
