    Hello all.

    My truck has the hardest time starting after it is very hot or very hot outside and under the hood.

    What are my points of interest to check and correct these issues?

    Your ideas are greatly appreciated.

    Was this issue ever resolved? Looking for the answer to this myself. Just got a 96 Taco 2.4L, reading other places it might be the coolant temp sensor or an air sensor near the filter.

    Yes it was... it was the cooling temp sensor. The faulty sensor was telling my computer that my engine was line -10 degrees when started. When the truck warmed up, the sensor was telling the computer it was only 32 degrees. So the idle would run high trying to warm up the engine still when it was already warmed up. Thats also why it wouldn't start. The faulty sensor was making the computer tell the injectors to give more fuel at start. Then it would smell like fuel when it wouldnt start. But Fixed the problem right away bro. Good luck with ya....

    Yeah I have been reading online that a faulty coolant sensor or air sensor can cause this. I have tested the air sensor by simply unplugging it, and the truck starts no problem. I guess replacing it would solve the problem...
