First step is to figure out what's missing... spark, fuel, air. Unless somebody stuffed a rag in your intake, air is probably okay.
Step 1: Turn the key to ON and listen for your fuel pump to prime
If yes, see Step 2. If no, check fuse and relay for fuel pump, bypass ceramic ballast resistor on inside of driver's side fender.
Step 2: Remove a spark plug and hold it against a ground while cranking. Watch for a bright blue/white snapping spark at the electrode.
