Hi and thanks for using 2CarPros.com.
Blue smoke from the exhaust indicates oil being burned in the combustion chamber. The unburned fuel smell may indicate too much fuel being injected which can be the result of many things.
Take a look through this link. It discusses causes and ways to repair. Also, if the check engine light is staying on when running, have the computer scanned to find codes. Most parts stores will do it for free.

If interested, here is a link showing how to use a scanner:

Let me know if this helps or if you have other questions.
Take care,
Joe
