My Park Avenue has trouble cranking over (Turning over).

If it's slow to crank and the battery is 100% charged it may be a starter issue but the blue smoke concerns me. I'd say perform a compression test but it's not cranking. See if it will crank with a few or all of the plugs taken out. If not you may want to look into it being a weak starter, a frozen pulley, jammed flex plate. You can also use this link to get a second opinion as I suspect some more hands-on testing is required by a mechanic. https://repairpal.com/repair-shops Alex
