Car turns over freely and already changed the timing chain, what else could it be??
you say everything works on the road but it just won`t start, so I am guessing you have had it run okay after the timing chain was installed. there fore it could be an ignition or fuel supply problem when trying to start. check for both to see which it is. if you have anti-theft on the car it may have activated, there will be a red light on the dash flashing while trying to start.
Engine revs up and down while driving
How is it at idle? A fast idle might be the result of a vacuum leak. Is there a check engine light with a code? Did you clean the mass air flow sensor?
