This morning I had a bit of a scare with the car not turning over.
The starter spun but the solenoid did not click.
I tried several times and eventually it cranked fine and fired right up.

Now that I am looking at the circuit diagram on p. 4-5, it seems that as long as the starter motor is spinning, then both motor and solenoid have the power; therefore, the starter relay should be fine and I am up for a starter replacement.
Is that correct? I was just trying to eliminate the possibility that I would drop a new starter in and still have a problem due to the relay.

So yup, probably new starter. Happened to me last month. First went the relay route (when in doubt try what's easier/cheaper first), but it ended up being the starter. It happens.

next time take a broom and tap the solenoid a few times and it will turn over .. and proceed in doing what plplplpl suggested :p

I already ordered the starter from Rock Auto, noticing that the solenoid was $300 while the starter was $90. Who buys those solenoids? It is 3x cheaper to take one off a brand new starter.

It’s easy enough to test an automotive relay if you have a battery (9v should work if you don’t want to connect directly to the car battery) and a multimeter. I can’t recall the starter circuit off the top of my head but there is a shunt on the starter from main power input to another connection. If you are in an area where roads are salted that may be corroded.

Some relays can be very tricky to test. Do not ask how I know.
Well, I am going to tell you anyway: I drove another car for a year with the main ECU relay acting up and stalling or failing to start the engine randomly. I was going bonkers before I found which relay it was.

Finding which relay is acting up may be a pain, but testing the suspected relay is simple. I believe the starter circuit only has a single relay so that should be easy to check.

The relays might be fine when you test them but still strand you away from town. At least MOSFETs either work or they do not. I wish cars used MOSFETs everywhere.
