Is it kicking back against the starter? You may have a bad starter, cables, or a bad ground. You can also hook the distributor wire to a switch and crank the engine over then turn the ignition on. That will take care of the kickback against the starter if it's what you are experiencing.
I pulled plugs 123468 and left 5 and seven there. It turned no problem till it hit those cylinders. I then put the battery charger on and it was showing 48% so maybe that's it. I'll keep the post up just in case
