No spark condition

[MikeyB67]

I've got a 93 Acura Integra, 1.8L, 5 speed. past few days I had to crank it for about 30-45 second before it would start. Then yesterday while driving it just shutdown and wouldn't restart. Used a Fluke to test coil and it read good...ohms matched what the Haynes manual siad, also had battery voltage at the coil primary leads. Used the Fluke to test 3 sensor in distributor and all readings matched book too. Wire colors and directions in book weren't clear enough to test ICM. I figured ICM is the only thing left...so I replaced it. Still no luck. Cap and rotor aren't new, but don't look bad either. Car cranks great, just no spark. Is there something hidden in this system that can shut off the spark even when there is power at the coil? Not sure how to test the PCM, but thinking that's now the only thing left. Any help would be appreciated. Thanks.

might be the distributor itself or timing might have skip a tooth

Are you 100% sure there is no spark? How are you testing? This sounds a lot more like a plugged fuel filter.

There is another thread like yours, maybe distributor rotor? From my experience

Replaced the timing belt about 8 months ago. Figured it couldn't be the timing, because I don"t get any spark, but the rotor turns just fine. Checked for spark on more than one plug wire with a spark tester, then a regular spark plug to make sure. Book was specific about checking OHMs on the 3 sensor in the distributor and coil to make sure they are good. However, I remember a few older cars having a "pick up coil" or "Stator" in the distibutor to tell it when to fire the coil, but not sure if this car has that kind of set-up deeper in the distributor where I can't see it. Was gonna try a new distributor, but it's $244 and I already wasted $55 on the ICM. Does anyone know if the tac could shut off the spark...maybe giving the wrong or no reading to the PCM or would it even allow power to the coil if that were the case??? I appreciate all the help so far...please keep it coming, cuz this thing is kicking my butt.

Replaced distributor and still no spark. Also no pulse at the injectors testing them with a noid light. I think the computer is fried. If anyone has had or resolved a similar issue, please let me know. Thanks.
