can you turn the engine by hand?
for what is the good life if not doing things thoughtfully?

I can turn the motor over by the fan pretty easily. The belts just slip around the pulley but the engine does turn quite easily.

it sounds like a bad contact in the solenoid. it energises, but doesn't pass enough current to run the starter. could also be a bad connection at the battery or starter, or possibly a bad ground.

For a $10 part, just be careful. I'm not sure what really happened to me, but.... Every once in a while I would turn the key to start and nothing would happen, then, on my way home from a show, my car was running hot and suddenly my starter started running. I turned the key off, and it still ran. I had to pull over and disconnect the battery as it was almost out of power with the starter smoking. I sat waiting for AAA and everything cooled down. I was hoping to just disconnect the starter, but it wasn't that easy and I wasn't sure the car would run without it being in the circuit. As the tow truck showed up, we decided to push the car to start it, but he was in the way and it didn't work. I had him pull way ahead, and as I put the key in the run position, I noticed I had some power, I tried the starter and it started. I made it home (160 miles) and that was the last time I could start the car. I replaced the starter, and then the solenoid. I'm not really sure what caused it all to happen, but it could have been the solenoid? Jim

open up the starter or get a different one
live every 24 hour block of time like it's your last day on earth

A bad battery cable can do that too. It will carry enough current to click the solenoid, light up a test light and show voltage on a meter but not carry enough amps to crank the starter.
Try the booster cables right on the big starter lug.

The solenoid itself doesn't take much to operate in the way of current. Since it won't continue to work you have a problem getting current to it - wiring, terminals, low battery, etc.
If you don't have the power to make the solenoid continue to work then you certainly don't have the juice to crank the engine over.
If you get the power sorted out and the starter still won't crank then its likely the contacts in the starter are shot. This is nothing more than a big copper washer and if you take the unit apart you can usually flip it over and get a bit more life out of it.
This is not really a true statement. Actually the solenoid takes a fair amount of power and you have to understand the "trick" as to how they work.
First the starter MOTOR must have continuity. This is because when the solenoid pulls in, there is a bigger, heavier, higher current winding IN THE SOLENOID that is IN SERIES with the starter motor. This winding draws a LOT of current through the starter motor to ground and is called the PULL IN winding. WHEN (if) the solenoid pulls in and makes contact, the circuit now puts battery ON THE STARTER motor main terminal (output of the solenoid) and this little "trick" NOW DISCONNECTS the "pull in" winding because there is now battery on both sides of the winding. HOWEVER........
There is a SECOND winding in the solenoid wired to ground, called the HOLD IN winding. This winding draws less current, and does not have the power to "pull in" the solenoid, but it is stil activated during cranking, and therefore "holds in" the solenoid
WHAT ALL THIS MEANS is:
IF the solenoid does not get enough voltage from the firewall relay, it won't pull in
IF the solenoid "pull in" winding is open, it won't pull in
IF the starter motor has a problem, such as a broken brush spring, and therefore is not electrically "continuous" to ground, the solenoid won't pull in
All this is starter/ electrical troubleshooting 101
Make sure the battery is good, "up" (charged) and that the posts, cables, and connections are clean. There is only two ways to make sure and that is to either take the cables apart and clean them, or measure with a voltmeter UNDER LOAD
Take a voltmeter from the block to the battery post, and jumper the starter solenoid, and measure the voltage. Make sure you have AT lEAST 10V and that is the bare minimum. At this voltage the engine "should be" cranking.
Move your positive post around to the relay,follow the cable, and down to the starter, check both the solenoid and battery posts. IF you have good voltage, say 11V or more, and the starter won't crank and the solenoid won't click, IT IS TIME to yank the starter.
In this day and age---and especially with reduction starters--I'd just go buy a replacement. The point is that if you have to ask how to troubleshoot this problem---and I'm not trying to be wise, just stating facts--then you probably don't want to try tearing into one of these starters.
