Having some issues figuring out out a problem on my ae86. After extended periods of highway driving it wont crank over. You can here the solenoid click but nothing happens. The battery reads at 13 volts after these drives so Im guessing thats not the issue.
Possibly need a new starter?
heat soak?

Thats what im thinking but have no idea why it would happen all of the sudden.

The weather is getting warmer, so that might be enough to push it over the edge. If it hasn't happened previously in hot weather, something in the starter could be getting flaky and just can't take the heat anymore.
Have you checked the ground from the engine block to the chassis and from the chassis to the battery?
Where is the solenoid physically located and is it in an area where it gets rather hot after one these long drives?

That would be my guess - seen that happen before.
Yep, it's starter heat soak, a problem I know well from my AE92. A full starter motor rebuild will help to reduce the starter's susceptibility to heat soak. A starter heat shield (like the wrap you can get cheaply from Summit) will help to keep it from getting hot in the first place.
In reply to GameboyRMH:
Looks like ill need that. The car has the 4agze and the supercharger is right above the starter.
I had this happen on one vehicle and for that one it turned out it was corroded connections to the battery. It was driving me crazy. I took off both the battery and starter and brought them to be tested at an auto parts place. NO problem. So then I started looking at every connection and found this hidden problem.
So it could be a bad or weak connection somewhere.
It could also be a bad starter solenoid.
If the brush holders are corroded to where they are locking the brushes in place, it might start fine cold but when the housing expands with engine heat, it doesn't make good contact with the commutator anymore.
Would explain the suddenness.
When I had this problem with my 914-4, I put a starter in it from a 911
In reply to Knurled:
Im fairly certain the starter is original to the engine, if its not its very old. Corrosion could very much be a factor
Nippondenso starter? Change the contacts in the solenoid.
Other starters? Sometimes adding a relay to the trigger circuit to make sure you get a full 12 volts to the solenoid f om the ignition switch.

Im guessing this is the correct starter blanket thing for my purpose?
They All Do That Sir. Eventually.
Very similar to "The Dreaded Click" in Harley world on Evo's. I solved the problem with the 20v Rolla the same way: Add an additional relay. I used the generic Ford starter solenoid. Wire it so that your starter solenoid wire goes to control the aftermarket (no one would seriously use a Ford part on a Toyota) Ford relay and the relay switches +12v from the battery to the starter solenoid and starter. Hit the key and the Denso solenoid pulls in and the (not a) Ford solenoid adds juice to the motor and you're off.
