ok.. so you have spark and fuel getting to the plugs..but no one has mentioned the possiblity of loss of compression...put a compression gauge on all the cylinders they should all be over 100 psi and within 10 percent of each other.. if you don't have a compression gauge..sears sells cheap ones ($20)......compression , spark and fuel are the only things that are needed for the engine to run..granted the air/fuel ratio has to be correct and the spark has to be timed.. but with those three present the car should run...good luck
