Ok here is the story. Yesterday I put the new catback on and now the car wont start. I kno it had some old gas and thinking that from being up so high on stands the tank got all mixed up. I put new gas in it and it is getting fuel and spark but still wont start. I was wondering if there is any other fuses i should check. Ive checked all the ignition ones under the hood too. Now a few months ago when i took the car out of storage i never took out the old gas just put some stabilizer in it and like 5 gal of gas. Done this like twice. Was thinking it just got some old gas again because when i try and start it has a funny smell

Cliffs:
Car wont start
Think its bad gas from sitting to long
Any Ideas

 

got it change the plugs and put some gas treatment in it
