Ok found the issue. Did all posted and still would not start. Got a new distributer and still nothing. I took carb cleaner and put a 1 sec spray into #2 chamber and its wanted to start. Then pumped the gas pedal 8 times and it almost started. Think the fuel pump is not pumping enough pressure to the carb. When I look down the carb the jet spray is not strong and the more you pump the weaker the spray gets until almost nothing. Why do you think?
Hello All,
Hope all are safe. Strange problem just started. The engine will not start. I tested the spark plug by putting spark plug in spark plug wire, grounding the metal of spark plug to engine. Very low spark, sometimes no spark. I installed a new coil and ignition control module, cap and rotor but same thing. I tested the positive wire to the distributor with multimeter and got 12 volts and when the engine is cranking 9 volts.What else could it be? Does the distributer need to be replaced? Any thoughts are greatly appreciated.
Thanks

Just confirmed. Removed old metal fuel filter and installed clear fuel filter, but did not install other end to carb. Fuel fills half of the filter but never gets to other end. LOL and yes installed correct end of filter to fuel IN side.so seems 100% fuel pump issue. Thank you all for your advise and suggestions. Thanks!
