Is it that when you turn the key, the engine turns over like normal starting, but it will not fire and start running? Is that what you are trying to say?
I assume it has been sitting throughout the winter.... With that said, the first thing I would check on; have someone kneeling down close to the gas tank. Then turn the key to the on position but do not try to start it. A faint "whirring" sound should be able to be heard as the fuel pump primes the injectors, it will only run a very short time and stop. If no sound is heard there could be fuel pump problems. The fuel pump is electric and in the tank.
if you hear the fuel pump running for a few seconds, then next go to the engine compartment and (if possible) remove the intake from the throttle body side off the air cleaner. With someone watching, again, turn the key to the on position and press your foot on the gas pedal. You should be able to see the butterfly valve plate move.
What I just mentioned are issues which have been known to happen in the triton series engine.
Beyond that, a systematic check to find out if you are getting spark, etc. If, you are the type to work on it yourself. If not, take it to a reputable mechanic.
