I recently replaced the distributor cap, rotor button in cap as well as changed the coil out. She started fine but after it got hot after initial start it would have a lot of trouble starting even with much cranking. Now it will not start at all. I checked the codes and it comes up P0756 and P0420. I even took off the positive cable from battery in attempt to see if computer resets but I still can’t get ole Betsy to come back to life. Any ideas to try this time?. Thanks. Abert

Neither of these codes has to do with it running. Most common cause for your issue is the ignition module. They tend to break down after they get hot, leave it set over night and it starts right up till it gets hot again…. Replace the ignition module and it should get you back on the road.
