Ok so i have a 97 civic hatch with a b16. i put buddy club stage 3 cams in it and it wont idle and i know why that is its because i a stock ecu, but could those cams have any effect on it starting it will turn over and sounds like its going to start but it doesnt sometimes it will start fine and some it wont and i have to push it and it will start

 

i am not aware of the idle being rough just because you have an stock ecu and upgraded cams? can someone enlighten me with this.

and for the car not starting, is you timing correct. if the timing is off the car will not start.

 

could be timing or do a voltage check on your started, alternator and battery. do whats easy first than think about the other stuff
