So when the car is cold it starts and runs fine. Once it warms up it stops firing and wont start back up until it cools off. I have changed the ignition module and the crankshaft sensor but that did not fix it. Can you steer me in the right direction? I was also wondering could the coolant temperature sensor affected that way.

Hello, I'm Danny.

Yes, the coolant temperature sensor could cause the issue you mentioned in you post. It's possible once the car engine is warmed up it then sends a false reading to your vehicles computer and causing a no-start condition until cooling off. Here is a tutorial showing what is involved for replacing a coolant temperature sensor:

I've attached picture steps below on replacement of the coolant sensor on your vehicle. Hope this helps and thanks for using 2CarPros.
