2003 C230 Coupe sitting for 8 months needs to pass SMOG

I have a 2003 C230 Coupe that has been sitting in my drive way for the past 8 months while I was away on duty. Now I need it to pass Smog in California in order to renew my registration.

I have already changed the oil, and added a full tank of premium gas. Are there any tips or tricks to make sure it will pass smog?

Also, for some reason the gas cap will not line-up and screw on correctly. Any ideas?

Thanks in advance!!!!

I would run techron fuel injector cleaner through the system. If you can't get the gas cap back on, it will set off the CEL (which I assume would be an inspection failure in CA?). You may need to replace it. It could have melted in the sun.
