92 4runner stalling help please!!

[ZachB]

i have a 92 with 200,000 miles. When the engine is cold or it has not been started in a while, it starts up easily, but after driving it or letting it idle for about 3-4 minutes it stalls out and will not start, the engine just turns over. I have to let it sit for a while and then it starts back up only to repeat everything. Anybody got any ideas?

I would check fuel delivery. It could be a clogged fuel filter or a bad fuel pump.

Could be the head gasket, with water leaking into the cylinders after the thermostat opens. Happened to me on a civic once. What a pain to replace!

FIXED IT!

it was the circuit opening relay located on right side of the dash board. I pulled it out and it was all corroded so i replaced it and it no longer stalls. thanks for your guys help anyways!

Sounds like you may have a windshield leak on that side. It should not be corroded. The same thing could happen again. Congrats on finding it though. What circuit does that relay open?

it was a relay for the fuel system. exactly what it did im not sure.

but ill have to look around to see if i can find a leak somewhere. thanks!

Circuit

Same problem 1 month ago. Relay works in conjunction with fuel pump. You'll notice it click before your pump starts whinning.
