My integra just died on me while I was driving. And would not start after the incident. I have fuel going to the cylinder, checked the pgm fi relay and is good. I also checked all fuses which are fine. Also checked timing belt to make sure it did not break still ok, Also replace distributor cap, rotor, and ignition module. I have spark and gas but still does not start? Could it be the ECU?

Hello,

It sounds like an issue with the crankshaft position sensor.
Over time with heat and vibration form the engine the crank sensor can malfunction and that will send error signals to the ECM. Which will shut down the engine.
The engine can stall regardless of the vehicle moving or stationary.
