Question about 1996 Toyota Tacoma
1996 tacoma pickup 4 cylinder, 5 speed.
when the engine gets warm and you stop somewhere for a few minutes the engine will not crank, just turns over and over.Starts great when cold and runs great allways.Toyota mechanic checked fuel pressure and said it was fine. He is thinking maybe crank sensor, or module in the distributor
Anybody got any ideas
I Hope You All Appreciate This FAST and EASY Inexpensive Repair That Even The Toyota Dealers Dont Seem To Know How To Fix !!! The Problem Is The Air filter temp sensor. Look On The Left Side Of the Air Filter Housing and Disconnect The Plug Thats Attached To The Spark Plug Like Plastic Sensor Mounted on The Side Of the Air Filter Housing, Now Go Start Your Truck !!! Your Truck Will Start And RUN Fine Now ! Replace The Sensor Approx $59 at Autozone... This Should Fix 90% Of Your Problems If your In the other 10% and it does not Fix it , Email Me and Ill See If I Can Help !

It seems that this problem is happening to quite a few people.
This problem has been going on with my 98 Tacoma for almost 2 years now. It doesn't matter if it is summer, winter, spring or fall, and after replacing the MAF, Coolant Temp Sensor, and Throttle Positioning Sensor it is still happening. I used to sit and wait the 30 - 45 min to let it cool and it would start right up, but now I have started carrying a gallon jug of water in the bed of the truck just in case it won't start again.
Mine must be vapor locking bc by pouring the water over the fuel rail it causes something to click on the engine and then it starts right up. It has worked every time I have done this trick. I guess that the fuel condenses back to a liquid and fires right up. Hopefully this helps and if anyone figures out how ti fix it please let e know.

Joemechanic got it right, just had a problem starting it and disconnected the said part, fired up without a problem! do what he says!

Same problem with my 1995 Tacoma. Took it to a dealer and they come up with the coolant temp sensor was bad. It was telling the computer something was wrong with the coolant temp (even though the gauge was mid line). The computer starts to idle the engine high and wouldn't let it start untin the coolant temp cooled off. They replaced the sensor this afternoon. I drove it about 60 miles or so then shut it off. It starts fine now. It'll take a few weeks to actually trust it but it seems like it works fine now.

Here is a solution I found on another forum:
Replace the fuel injectors.
They claim that when its hot outside, the fuel injectors leak out the excess pressure in the fuel line. (fuel injector is essentially a little valve/nozzle) This extra fuel causes the engine to flood (too much gas, too little air) and you have to wait for it to dissipate before it will start.
I do not know why it seems to be linked to outside temperature - if the engine is at operating temperature it should be the same temperature on a hot or cold day. But lately, mine is doing it all the time.
I haven't tried replacing mine yet, but this is another possibility if you are still seeking a solution. I've read this will fix it...

I'm the 10% that the new temperature sensor did not work. What did work was leaving the temperature sensor disconnected. Then a second superior solution that worked was to add a 100 ohm resister in series with the temperature sensor. This makes the electronics think the air temperature is slightly cooler than it is. Because the electronics checks the air temperature with the coolant temperature, I think what is really happening is increased resistance in the coolant sensor wiring. But for the past several months a 100 ohm resister solved the problem.

If I pinch off the fuel return line it will start. It will also start if I squirt fuel in the intake. So, obviously the mixture is too lean. I know the fuel is boiling in the injector rail. I have checked the fuel pressure and volume hot and cold. They are fine. I have tried to insulate the fuel line and have even gone so far as to install a different fuel line to move the filter away from the engine. No help. I have replaced the air temp sensor and tested the water temp sensor. BTW, there are two water temp sensors. One for the gauge and one for the computer. No help from Toyota either. They say it is the fuel. And even though I agree they should be working on a fix. I guess their fix is for me to buy another truck. I have installed a fuel shutoff solenoid on the fuel return line that can be actuated for a moment from inside the cab.

I have my key ingintion moves and i think it is bad because when i rotate right it starts up
i starting to have problems when it is cold out

I also tried the removing the gas cap. It actually worked the first time. Then a few times it didnt help. I removed it to let the pressure off then installed it again. I have been meaning to replace the gas cap and see if the helps, just seem to forget about it while its is starting ok.

The only thing that seems to help me at all is to take the gas cap off and then put it back on. most of the time it will start right back up.

Thanks Joe, this was the answer I was looking for!!! Fixed my probem changing this simple air filter temp sensor for $55 bucks. Thank you!!!!!

I also have this problem with my 95 Tacoma. I've been working at it and researching it for the last few months with no solution. I do have some back ground on engine work, and I have determined that the likely problem is:
Lack of spark
Too rich air/fuel mixture
(i've eliminated vapor lock - which was my first thought)
The next approach I am thinking of trying is to "jump" the power to the starter with ignition in the "on" position. This should work, as it push starts easily. If this is the case, then that means there must be some signal from the ignition that is incorrect when the engine is hot. If this is the case, then we just need to know the wiring of the ignition switch and start testing each connection by disconnecting them, and eventually by process of elimination we can point out the problem signal/sensor/processor.

I RAN INTO A PROMBLEM MUCH LIKE THIS ONE ON A 98 S10 PU I OWNED. WHEN I DID A FUEL PRESSURE TEST IT WAS WITHIN SPECS BUT I DIDN'T DO A FUEL VOLUME TEST. WHEN YOU FIRST HIT THE KEY THE FUEL PUMP KICKS ON AND GAVE ME PROPER FUEL PRESSURE BUT WHEN I PULLED THE LINE AND HIT THE KEY IT BARELY SPIT OUT A 1/4 CUP OF GAS. I TRACED THE PROBLEM BACK TO BEING AN ELECTRICAL SHORT IN THE POWER SUPPLY TO THE PUMP.
OH AND BY THE WAY I AM FACING THE SAME EXACT PROBLEM ON OUR 96 TACOMA DELIVERY TRUCK. I'M GOING TO BE DOING THIS TEST HERE SHORTLY AND I WILL LET YOU GUYS KNOW WHAT I FIND OUT.
