My Altima died a few days ago while driving, just sputtered out like i ran out of gas or something. Since then I haven't been able to start it...the engine will crank, but no ignition. The plugs,wires, distributor, rotor are all new, as in, i just replaced them to try and fix the problem. The plugs spark fine, but the cylinders are flooded to the point that the plugs are submerged in gas. I think thats the problem, but I can't figure what would cause that. Any ideas?? I'm desperate here, i've tried everything I can think of!
