I think you mean engine cranks but won't start? If so, there are several possible causes for that to happen; lack of fuel or ignition spark among those. Can you try starting fluid? - if it starts and runs for a few seconds on starting fluid, that would narrow the number of possibilities to either fuel delivery or fuel supply.
You also mention the check engine light not coming on. Does that mean it doesn't come on even if you just turn the ignition switch on with the engine off?
