My 98' Outback Legacy won't start (intermittently) when it's been
running for a while or if it's is hot outside (above 75 deg). The car
won't even crank--just a click sound. Usually if I wait about 20 mins
it will start just fine. All electrical devices in the car work--
stereo, headlights, horn, radio, etc. It will ALWAYS start if I have
someone jump the car.

So...I replaced the battery and it still won't start on occasion. Any
ideas?

hmmm...I think some 'older' soobs had crank angle sensors that would
become intermittent with temp.

dunno about '98 and dunno if a CEL would be generated.

Always a good idea to first verify the battery cables are clean, not
corroded and tight on the battery posts.  But the problem sounds like
a starter solenoid going bad and/or the brushes inside the starter
motor are worn.

Ahh, you're right. It doesn't crank!

Tony, carry a length of 2x4 or similar with you, next time the problem
occurs, strike (more than a tap, less than BASH) the starter and try
again. Also, try wiggling the starter cables. If either of those things
work, should point you in the right direction. (solenoid contacts likely)

If it clicks and doesn't start it's the starter.
A little known seceret: SOME sub's have a rebuildable starter. If it has
been replaced in the past your probably out of luck. look at the solenoid,
if it has the ability to remove the end cap by screws or nuts than you can
rebuild it.

Go to the dealership and ask for the starter rebuild parts (I don't know
what the exact name is for them) they are the two wire lugs that go into and
out of the solenoid. (can't be too expensive)
Remove the starter
Remove the end cap
under this is a copper "mushroom" shaped piece
Replace the two wire lug parts. The solenoid action pulls the mushroom piece
and joins the two lugs; the arc over time and wear out.
On the mushroom piece, look at the "lip" and clean the arcing off of it.
Reassemble and install starter.

I have not yet figured out what subies use the rebuildable starters and what
ones do not....

Just for the record, the starter is on top of the bellhousing on the
drivers side. It is easily accessible from the top of the engine
without crawling under the car. So a rubber mallet or deadblow hammer
might work for persuading the solenoid to engage. Also looking at it
to assess the rebuildableness of it shouldn't be too hard.

I love how subaru makes these cars easy to work on. All the engine
accessories they could stick on top are there for easy access. I don't
even have to lay under the car to take off my oil filter. I just get
down on one knee and reach under the front bumper. Brilliant designs.

This is common with older Toyotas, the contacts wear down. Even before I
knew much about cars I became familiar with this condition! Kind of an
easy fix, depending on where the motor is located...
