Hiya peoples!!!!
Hoping someone can help with this one. have one of those pesky ghost's in my electrical system. have an 86 4runner 22re EFI Automatic trans. starts and runs great.
THE PROBLEM:::
when it's been driven for a while and let it sit for about an hour, then try and start, it'll just sit and turn over. if you turn the key back on and off it'll start for about a 1/2 sec and then just just cranks over, keeps doing this. eventually it'll start after about 10 real quick turns of the key engaging the starter briefly each time, let it do it's quick chug then turn back to off.
It also does this if it's sitting in the sun on a real hot day, without going anywhere, has to be above 80 though.
Any thing to check come to mind?
It also did this last summer, but never though about it once the cold came. now it summer again and it's back.
oh checked the coil for spark last summer, spark was good then, asuming it hasn't changed!!!

Thanks
Rick

 

I really can't help you, but I hope you end up better than my buddy with a 99 who's door caught fire as he was driving down the road yesterday morning...

Good luck!

 

OUCH! caught fire! just a bit of a short huh! lol!

hope your buddy wasn't hurt? How bad his rig get damaged?


Mines more of a nuicence problem, plus sorta embarasing when a girlfriend is with me.
Nothing worse than a car that won't start right when your on a date. well I guess being on a date and having your door catch fire would be worse! lol!

Pesky Ghost! most of my friends say it's a gremlin and it's gonna get me some day LOL!!!!!!! These are people from Big Three families parents or them are generation factory workers for one of the big three here in Detroit area Most don't even alow toyotas to park in there driveway. it's all good, I make them park there rigs in the street when at my house.
I tell em to check how much of there truck or car was built here in the US! they just sort of grumble.
Toyota's new full size truck will be the only truck in the entire US where every peice of the truck was built in the US. seats, motor, electronics, every little peice. the big threee can't claim that. wait and see. New add campaign comming soon. Oh what a Feelin!!!!!!!! LOL! oh wait i say that when i'm wrenchin!

 

Had the same exact problem a while back. Just to go Advance Auto Parts, let them check your battery for free, and it will probably be dead, mine was. I was about to get the starter replaced, but decided to check the battery. Mine did the same thing, if it was hot and the car sat for a while, I would have to turn the key about 10 times before it finally cranked. Check the battery.

 

battery is good, just checked it a couple weeks ago. it does crank and turnover and has good spark, and like I said, it'll rumble every time you first turn it to start and the starter engages, but it's only for a milisecond then just cranks. makes me wonder if it's some kind of temp sensor associated with the injection system. maybe a cold start sensor or something.

Thanks for replying
Rick

 

man, that is weird...

My buddy was fine, he jumped out the passenger door as fast as he could. Haven't talked to him today yet to see what they are going to do with it but the rear end crash was pretty bad. He was going 70 (cruise control, he just had gotten a ticket) and all of the sudden the ass end of the truck was in the air and he got it off the side of the road and there wasn't anything in sight! Not a car on the road! He thought he was going crazy til he found the yukon xl down in the lower side of the median. Then the drunk ass has the gaul to jump out and yell at him b/c he was "stopped in the middle of the hiway" haha! :pat: Oh well, I feel bad but it looks like I'll be getting a set of ClassicIIs out of the deal for cheap

haha, i know the exact feeling about the car not starting w/ the females!! I was having some battery contact problems with the contact actually arching between itself... anyway... i'd have to open the hood and move it then it would work fine. Just embarrasing to have to open the hood. I couldn't imagine if that happened on a first date or something

 

hey let me know what you find out my 87 does the exact same thing ...i almost wonder if the heat has any thing to do with it ?

 

yes mine too. if anyone knows let me know too. first time owner of a yota. lots of fun but the gremlins starting to piss me off. almost stock (86 4runner 22re auto on 31's. 2.25 exaust front to back) If it keeps up i am going to strip it. (all of it. interior, wireing, motor, tranny, everything. will be skeleton of toyota with 350 chev, 42's and barly road legal.) but i dont want to kill my yota yet. PLEASE LET ME KNOW GOT MANNY MORE QUESTIONS. (HA666@SHAW.CA) thanks Sloth.

 

hey rick,try to put a fuel gauge in line after the filter to the fuel rail...and keep an eye on this while you crank...it might be fuel related..at least 30 psi? and check for spark at the same time it quits on you..then you're halfway solving this gremlin...hehehe

 

My '94 had the same problem. I had the ECT mod on it. As long as I had the ECT mod cut off, it worked fine. But if I had it switched on, I had the same problems as you guys. It is most likely cold start related. I would bet money on the temp sending unit for the ECU, not the unit for the gauge. Hope this helps.

 

Check the FSM

Theres a cold start timer switch that activates when the Cold start "swithc" is open (aka hot start).. maybe its not resetting...

Could isnert a manual override...

Nuthing like having an "airplane" style check off sheet to start the car

 

Could be. Your ECU temp sensor (2 wire plug)(not the temp sensor for your gauge) tells the ECU if the engine is hot or cold, and adjusts the air/fuel ratio accordingly. So if the sensor is bad, the air/fuel ratio will be wrong. In your case, the engine thinks it cold, so it dumps as much air and fuel as possible, causing the stumbling. In my case the ECU thought the engine was always warm, so on cold starts the cold start injector wasnt firing and it took forever to fire up.

Unplug your ECU temp sensor and check resistance on it, starting from a cold start, all the way up to when it warms up. If you get a crazy reading when its warm, thats probably your problem. A new sensor is like $25 from the parts store.
