Hello. Welcome to the site. Thanks for coming. I'm Dan J. I'm here to provide as much

information and insight as I can, to best answer your question.

If the CEL is coming on that means there is a problem in the system causing it to set a code. You need to see what the code is and then diagnose what the problem is and fix it before it will complete a drive cycle.
