Blinking SES light, rough idle, now engine wont crank over..
What is your question?
The SES Light started blinking, and the idle was slightly rough. Dis a fuel injector cleaner and put non ethanol 93 fuel in. The light was still blinking and idle was still rough. Went to work for a 9hr shift, come out and now the engine acts like it wants to crank, but won't turn all the way over. Brand new battery, all the power works inside the vehicle. The radio has always had a mind of its own, it cuts off randomly and cuts back on when it feels Like it. The airbag light blinks all the time. I noticed a sort of burning smell when I drive it, I figured that was heater related issue or a tight belt, but it smells hot or burnt on the outside as well when I parked it. Could it be a bad coil pack, something slightly minor, or am I looking at a bigger problem?

Hello, the blinking SES light is evidence of an engine misfire, which is a big deal. Letting that go for any period of time can cause significant engine and/or exhaust damage due to an engine misfire which may have started as a coil, spark plug, fuel injector or even base engine issue in the first place.
This is your first issue, as the other issues such as the SRS light and the radio concern are likely not related.
You will have to have engine performance testing performed, and at this point, you could have multiple failures, possibly caused by the initial misfire that the blinking SES light was indicating. Too hard to guess in this forum, hands on testing is needed.
Good luck!
