Re: sputtering during idle blue smoke
You are burning oil, causing the blue smoke. It is mainly cause by worn piston rings. Also will coat your spark plugs with oily residue. Try an oil additive such as "stop smoke" or another such brand to reduce burning your oil and it may recondition your seal sand stop it all together.

You've already eliminated the spark plug & wireset, distributor cap & rotor. Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.
Components checked/replaced during a tune-up are: air filter motor oil motor oil filter breather filter fuel filter(s) fuel strainer PCV valve EGR valve spark plugs spark plug wires ECM or distributor cap & rotor cabin air filter transmission oil filter transmission oil engine coolant check all vacuum hoses and lines

to me it sounds like your just about to put water down your exhaust mate or your rings are binding up. I recon dump your oil and run diesel oil from now on and reset your timing belt before those new spark plugs end up in your lap.
If not getting fuel then the normal areas to check is the fuel filter, fuel pump but first the obvious is to make sure you have fuel in the tank. If this engine has a carburetor, remove the air filter houseing and pour a small amount of gas into it. Try starting it. If it starts and then dies it is a fuel delivery problem. If it wont start even temporily then I'd check things like wires, plugs, timing, etc (stuff to do with delivering a spark).
change plugs wires also .fill gas tank up put prestone or gum out fuel injector cleaner.drive car around several miles.give injector cleaner time to clean out injectors.wait until engine cool .change fuel filter.relief fuel pressure before changing fuel filter.
