What sensor needs replaced if car wont start

Hello, please don't just jump to a conclusion that the control module is failed. There are far more possible causes than that; more likely causes. Testing is required to find out what is going on. My initial thought is: are you using keys that are known good keys that are programmed to the vehicle properly? Starting fluid just means that you are circumventing a situation where fuel is not being delivered.
