View Full Version : 96 4 runner starter electrical

My neighbors 4 runner is having an issue. The starter continues to crank even with the key out. He disconnected the battery to stop it yesterday. I removed the starter relay which should isolate the ignition switch. It still trys to crank. So I think it's likely the starter solonoid. But without a electrical diagram it's my best guess. Anyone have this problem before?

I had that issue with my FJ40. Same symptom - cranked and cranked even with the key off and out of the ignition. At first I thought it was the ignition switch sticking, but while waiting for that part I found a used starter at the salvage yard, installed it, and fixed the problem.

The starter has a internal short. Just replace it and he's good to go

Probably the solenoid on the starter sticking like you are thinking....

Classic solenoid sticking. Rebuild or replace starter.

Thanks guys. The starter is what I guessed. But I wanted to be sure before I sent him off to buy the parts. And he can buy a decent manual while he is at it.

Buy the plunger & contacts from the dealer. Was just in mine doing this. Simple job once you get it out.

Since we're discussing 3rd gen starters, is the starter easy to remove when you pull the transmission for a clutch job? If so, it would seem wise to replace the contacts in it at that time, right?

I know what a treat 4Runner starters are when the tranny is still in the truck.

Thanks - Steve

Mine is easy to get to. . . :lmao:
But seriously... yeah just two bolts and a terminal.

Seriously-several 3rd gen owners have reported fire starting when this occurs. I believe the main cable reaches a heat level from the extended cranking.

Have an extinguisher with the vehicle so it is not needed.

Let us know if the new parts do the trick
