Default Occasional starter problem on T100?

I have a '96 T100. Every once in a while, it doesn't want to start. I
don't even hear it trying, yet the lights, etc. work. I keep thinking
it's from corrosion on the battery terminals which seems to accompany
the problem, but after cleaning them the problem sometimes remains. And
using jumper cables doesn't help.

The strange thing is that if I keep trying, it will eventually start.
But I hate to rely on that because some day it might not and I'll be stuck.

So I'm wondering if I need to get the starter replaced, or if it could
be something else? It once failed to start when I was at a garage, which
was awfully convenient, and they were going to replace the starter for
me, but then they decided to replace the battery terminal instead
because it started the next time they tried.

Thanks,
Trevor

There are some replacable contacts inside the starter. This will give
you a clue:

The Toyota stealership also has them.

Thanks! It sounds like that may be the problem. It is kind of weird that
it's not a consistent problem. I've had trouble for 3 days now, but the
last time I had the problem before that was about 6 months ago.

So how easy is it to get into the starter to change the contacts? The
most complicated work I've done is changing the brakes.

Thanks,
Trevor

If you go to: http://www.toyotanation.com/forum/sh...d.php?t=239741

One of the manuals on that page should give you an idea what you're up
against. I've only messed with older models (20r, 22re, 3zve) , in
4runners and hilux, so I have no idea what you're up against with a
t100.

My experience has been that if the contacts are bad you can hear a
click as the solenoid is activated, but the bad contacts won't allow
current to the starter motor. (The same thing sometimes happens with a
low battery.) If you have a worn starter communtator or a bad winding
in the starter you will sometimes hear the same thing. If, as in your
case, you hear nothing it is most likely bad wiring. Either corrosion,
a bad connector or even a bad ignition switch. I would check the
ground wire to the chassis as well as the ground wire from the engine
to the chassis. The solenoid itself could be going bad and not pulling
in sometimes. This can be proved by shorting across the solenoid with
a heavy jumper the next time it won't start. If it starts you know the
starter itself is okay. OTOH, You can jumper from the positive battery
wire to the solenoid small wire that comes from the ignition switch.
If it starts when doing this you have proved your solenoid, starter
and heavy wiring is good. The problem will be in the smaller wiring or
ignition switch.

The interesting thing is that it has been starting fine since Friday
afternoon. On the days when it was having trouble this time, the
temperature was below 20 F. (However, the previous time I had trouble
was during the summer.)

I've been told the last few times I got my oil changed that I have a
small oil leak, and it appears that it has been dripping onto the
starter. Perhaps some has made its way inside? I'm going to wait until
it's either warmer outside or the problem arises again before I try to
get to it and find out.

Well, I had a really hard time starting tonight, and the temperature
was above freezing. And it turns out it does click - it's not just
silent (I just hadn't been in a location before where I could hear it
clearly). I had to try many, many more times than usual, and it
actually started trying to turn over 2 or 3 times before it finally
started. I'm guessing that's because the number of starts it took made
it so that battery wasn't quite as fresh as it should have been?

I guess if it starts in the morning I should just drive it some place
that can fix it, since I lack both the parts and the experience. I'm
guessing I'm most likely to get someone who knows what they're doing
if I go to the local Toyota dealer. I just hope they'll be willing to
replace the contacts (if that's what it is), rather than insisting on
replacing the whole thing.

Thanks,
Trevor

I ended up taking it to Tunex, and they had a hard time believing I had
gone 235,000 miles on the original starter. They convinced me that I
would ultimately be best off with a new one (not remanufactured, but
unfortunately also not Toyota). They replaced it, and I now have no
problems starting. But I'm feeling a little bit of buyer's remorse today.

Alas, it's all better than no starter at all. :-) If it weren't
for credit cards, we'd all be walking.
