Turns over but takes about 20 cranks. I also was told to turn the key on and off to make the fuel pump get more gas in the engine. It doesn't pop over very well if at all. After I finally got it started and I let it run for 5 -10 minutes. When I put it in gear and pushed the gas, it quit and I could get it started again. I changed the main relay about 2 years ago. Seems like a fuel / ignition issue.

I suspect the Ignition Control Module (ICM), which is located inside the distributor, is bad, Be sure to coat the back of the ICM with heat transfer grease, otherwise the ICM won’t last long. I would also replace the rotor, while you have the distributor open. Use precision tip screwdrivers or you may mangle the fasteners.
