The engine will not start when the engine is hot. Need to wait ten to fifteen minutes before engine will ignite. When engine is cold, there is no problem.

Hi and thanks for using 2CarPros.com.

Based on your description, it sounds like the crankshaft position sensor may be bad. Take a look at this link:

What I suggest is to check for spark to the plugs when the engine won't start. Here are easy to follow directions on how that can be done:

If you find there is no spark, the sensor is my first suspect. Here are general directions for sensor replacement:

I have attached sensor location pictures.

Let me know if this helps.
Take care,
Joe
