" I accidentally disconnected something from the air filter" is pretty vague. Can you maybe upload a picture of what it is? Also, look around the air intake tube and the filter housing for anything that looks disconnected.
To diagnose the no start, you need to find out what is missing: fire, air, or fuel. I would also check the timing belt to make sure it's turning. That's located in the front of the motor, usually under a plastic cover. Pull the two or three top screws or bolts and carefully pull the cover away from the block and have someone crank the engine over while looking to see if the belt turns.
To check for spark, remove a spark plug boot from one of the plugs and insert a #2 Philips screwdriver in it, holding the screwdriver near a metal piece of the engine while someone cranks the engine. You should see a strong blue spark. Smell and feel the spark plug to see if there is gas on it.
Remove the air filter and make sure you can see through it when holding it up to the sun. Tap it against the ground to remove loose dirt and debris. Check the inlet hose to make sure it isn't obstructed.
Turn the key to the run position and listen carefully when you do it. You should hear a click and hear the fuel pump energize (it sounds like a whirring sound). If not, you may need a new pump or pump relay.
