93 accord lx turns over fine but not starting. How do i diagnose??
I replaced dist cap/rotor buttton,fire control module to no avail.

 

Is there spark at all? If there is spark then it might be out of time, if not, you've found your problem :D Also, is it getting fuel?

 

Needs fuel and fire, if it has both then it's timing related!

Pull the spark plugs and turn the car over, if you see fuel mist coming out of all 4 spark plug tubes or the piston tops are wet with fuel. You have fuel. With the spark plugs removed, insert one of the plugs into the spark plug wire boot. Make sure that the spark plug ground strap end is touching part of the engine. The exhaust manifold works! (best option would be to touch the ground wire on the valve cover if it will reach). Turn the car over and watch for spark between the gap. Do this for all 4 and this will tell you whether or not you have spark. Or if you have a spark plug wire test light you could use that as well.
