The engine will turn over easy without the plug because you are not building up pressure in the cylinder because the air escapes through the plug hole. With the plug in it will take more current to turn the motor over because you are building compression. Try jumping your battery with your car and see if the engine turns over faster.:biggrin:
Now we are jumping from too much compression to electrical what next. Maybe take a compression test, test your battery, if that is OK see how much of a voltage drop you have at the starter or test how much of a amperage draw you have. It is getting beyond just guessing at things and start doing some testing which should have been done in the frist place.
