I have a 1992 4runner V6 with about 170,000 on it. 4x4 5 speed
Ok say I go to leave and my truck is cold haven’t drive it in like 12 hours its starts right up. But say I drive to the store 10 minutes away and I’m in the store for about 20 Minutes ill come out and try to start my truck and it wont start.

What it does is turn over’s starts then dies. Kind of like a stall. But I can start it if I crank it and give it a lot of gas. But when I do that it idles really low like at 500 RPMs. So I have to hold the gas at 1500 RPMs for about 5 minutes to have it come up to about 1000RPMs Idle. Then it run fine till I turn it off.

This has only been going on for about a month.

I put in a bottle of thick stop leak in my radiator because it was leaking a little about 2 months ago. I don’t know if that did something.

What I have done is:
Cleaned and tested the battery- Good
Replaced cables and cap
Replaced radiator cap
Tested starter- good
Tested alternator- good
Tested fuel pump- good
Tested fuel presser- good
Checked for codes- None
Did a Code test- and nothing came up

Any Ideas what’s wrong?
Thanks for your guys help.

 

Check the ignitor.

 

replace starter contacts its a very common problem

 

I have a 1999 4Runner and I'm having the same exact issues. It would start fine in the a.m. or any time I havent driven for a few hours. It doesnt happen all the time tho. When it does happen I usually have to step on the accelerator when it sounds like it wants to fire up and it starts but wants to die. I usually just drive off as soon as it fires and its fine but if I dont do that it just dies again. I had the local dealership take a look at it and they replaced the TPS (Throttle Position Sensor). It was fine for a couple of months then the problem returned. I took it back and they had it for a week and was able to duplicate the problem once but was not able to diagnose it. All test were ran as well. No codes came up or anything. Unfortunately they said to wait for "hard failure" before they can fix problem. Any info would be appreciated.
