Could be a number of things dude....

If it's not starting then you're either missing fuel or spark. Not uncommon for the ECU's to fuck out- maybe try and find someone with a spare and chuck it in to see if it fixes the problem? Then there's the AFM, coil packs etc etc etc

just replied you about cam position sensor issues.

Cam position sensor will cause exactly these issues too, i experienced the same.
