Try checking for spark pull out 1 coil and boot and connect it to a spark tester. If you dont have one, just use another plug and place the plug on something metal and have an assistant crank the engine. If it sparks, you have ruled out the cam sensor and the ecu and the fuel injector cycling.
Then listen for the fuel pump running insert a short piece of stiff garden hose into the fuel fill inlet. Have someone turn the ignition switch to on position and listen for a short whirring sound. If you hear that then the pump is ok.
Then check for fuel at the schrader valve. Use a fuel pressure gauge if you have. If fuel pressure is present, then the fuel system can be ruled out.
Last check, assume the engine is flooded pull out the fuse for the fuel pump and start the engine while fully deppressing the accelerator pedal. If it wants to start after that put back the fuse and start it again normally.
If it still wont start, check the wiring of the MAF sensor. Because if the MAF sensor is disconnected, the engine wont run at all.
