97 Pathfinder intermittent no start

My 97 LE Pathfinder randomly wont start. It cranks but wont fire. New fuel pump, fuel filter didnt help. Power and ground are both good. I have spark. Whats going on?

Sometimes it also stalls at low speeds but starts right back up usually. Could that be a cam or a crank sensor?

check your injectors and dizzy cap. and leeds. test your cam sensor. some times you will get a spark at the plug but if u have carbon tracks on the dizzy cap it will be enough to stop your car firing
