'99 4Runner Wont Start When Hot (1 Viewer)

[toylndcrusr]

The title says it all. Well, mostly. It;s a '99 4Runner, 4 cyl. automatic, 2WD base model. We bought it from a dealership a few months back and right away noticed that when the engine was hot, say you drove the truck for ten miles in traffic, then shut it off, I wouldn't start until it cooled off. So I replaced the starter with a re-manufactured one from Advance. When I took the starter off you could see where the previous owner had been tapping it with something, and it looked new and had a reman sticker on it. Anyway, the problem persisted, so I replaced that starter with a 2KW unit from Toyota (Cruiser Dan). I was surprised to see that this too was a re-manufactured starter. Problem went away for a couple of weeks, but has returned. When the starter fails to engage you can hear the starter relay clicking. I think it has to be in the starter solenoid. Any suggestions?

Does it click once and do nothing or does it click many times in succession?

Thanks!

No prob, hopefully it was somewhat useful.. I would throw that question up on t4r in the 3rd gen section aswell- also try yotatech.com Im sure theres someone on there that can help you out.

Well, when you turn the key to the "Start" position you hear the relay, but the starter makes no noise at all. And it only happens when the engine has been running for a while and everything is hot. I am not cinvinced that this is a problem with the contacts in the starter because the last starter I put on was a reman from Toyota and I would sure hope they spec'd their remans for new contacts. Anyhow, anyone think I should pull the starter and tear into it to look at the contacts? I really don't want to but I reckon it's a logical next step in diagnosing this problem. At least this one has the four cylinder and not the dreaded V-6.

You didn't really answer my question.
If you are talking relay as in the starter solenoid, the relay is on the starter.

Oh, sorry, I mean "Relay" as in the electrical relay switch located on the USDS fender fender in the under hood fuse panel. It clicks, but the starter is silent and dead, but only when it's hot.

I'd test the relay, just because it clicks, doesn't mean it's working.

Usually the loud audible click you can hear from the cab is the solenoid.

It could still be the contacts. You should check the voltage at the small wire to the starter solenoid with the key in the start position.

 

[toylndcrusr]

Yeah, you have be standing by the underhood fuse box to hear the starter relay close. I want to test voltage at the small wire to the starter but the truck never fails to start here at the house where my tools are. I will pull the starter out and look at the contacts. At least this is a 4 cyliner truck and not the v6.

 

[raydouble]

The voltage coming from the NSS (neutral safety switch) is something else to check.

sounds logical to try checking voltage at the starter solenoid if it won't start.
Makes me think of the curse of running headers years ago...
