Remove distributor cap have someone tap the key while you watch the rotor inside the distributor if it does not move that is the problem then it could be the gear shear pin has broke or cam is not turning distributor.
So many of them things could have been checked to see if they was bad or needed to have been replaced. I see this a lot when someone goes to guessing on things and they can end up having a LOT of money invested and still not running.
My first guess since you've replaced all of them things is either you may have a ground issue or a bad PCM.
I would start by checking that you are getting power to everything that you are supposed to be getting power.
Then, I would check that you are getting grounds to everything too! You must have both in order for it all to work! If you are getting both and if you know how to check for both at all places, then I would eliminate the PCM.
If it turns out to be the PCM, try checking eBay.
Hope this helps.
MAKE SURE DISTRIBUTOR CAP ,ROTOR, SPARKPLUGS AND WIRES, OKAY IF ALL HAS BEEN REPLACED.IF NOT GETTING SPARK PROBLEM COULD BE IGNITION COIL FAULTY, ASD RELAY FAULTY,DISTRIBUTOR WITH CAMSHAFT SENSOR FAULTY OR YOU HAVE FAULTY PCM. CODE SCAN VECHICLE FOR FAULT CODE, IF YOU ARE GETTING SPARK PROBLEM IN THE FUEL SYSTEM, CHECK FUEL PUMP RELAY AND FUSE MAKE SURE FUEL FILTER BEEN CHANGED AND FUEL PRESSURE IS 39 - 41 PSI. CHECK FOR FUEL SPARK SEE WHAT GOING ON, VECHICLE NEEDS FUEL OR SPARK TO RUN IF ONE NOT WORKING ENGINE WILL NOT START.
No spark. I have changed out the distributor cap, rotor, wiring from coil to cap, and coil was replaced. I checked the distibutor by turning ignition key and observing the rotor turn. What else can I check. I did not observe a module.
You changed the ignition coil from distributor right?
secondly make sure distributor is not internally shattered (which is a common problem). Normally the current comes from Crank sensor or cam shaft sensor !
