Dunno about the vapor.
When it won't start, just go over the basics, spark, fuel, compression.
1) Compression - can be affected by internal damage, a non-op (for some reason) valvetrain . Pretty much, however, if you can hear the starter straining over each compression it's probably good enough to run. It's generally the last thing to suspect, but you've got some evidence right there when you crank it over trying to start it. For example if the cam gear came apart it will sound funny when cranked.
2) Spark - pull a wire, place it within 1/4 inch or so of a ground, crank it over. If it sparks then good, if not find out why. If it was running prior there's no immediate need to suspect the timing.
3) Fuel - this means dealing with D-Jet on your car.
3a) Turn the key on - do you hear the fuel pump run for a couple of seconds? If not there is something amiss. If you don't slowly press the pedal down with the key on and listen *very carefully* for the inectors clicking - if you hear them it means the FI system is powered up, if not the main power supply is not turning on (it's a separate green wire that attaches right onto the + battery terminal).
3b) If you heard a fuel pump, and you heard some injector clicks you *most likely* have fuel, you could also unscrew all 4 sheet metal injector retaining rings, give each injector a little twist, and pull up the entire fuel rail with all hoses and wires attached. Turn the key on several times (to ensure pressure is built up) then, with the key on, slowly open the throttle by hand and watch each injector. They should fire in pairs and make a nice spritz of fuel each time.
