check the cylinder compression, if it's under 75, it won't start and you probably threw a timing chain or belt :(

If it has all those things, I'd bet on a timing chain problem or something with the fuel system. Does it have spark and fuel at every cylinder? If the timing is off, it should be popping or coughing either out of the intake or the exhaust.

Security key?? Maybe. Shoot some starting fluid into the intake. If you don't get any fire from that then it has a loss of ignition. If it runs on starting fluid or tries, then you have a loss of fuel. If it backfires or runs really rough, then you have a timing problem. If it runs really rough without backfiring, then you have a dead cylinder and will need to check for spark, fuel and compression on that cylinder. OR those cylinders. Good luck.

probably not the injectors. could be fuel pump, but if it "seems" like its getting fuel, then I would check the spark plugs first. If them seem okay go with the fuel pump. Try turning the key half way. Not all the way to start just to the radio and stuff. usually if its real quiet you can hear the hummmm of the fuel pump starting up.

Timing and compression are your only things left. You can pick up a compression tester at auto parts store to see if you are getting compression. They screw into the spark plug hole (I apologize if you already know all this) and crank over the engine. If it is a timing belt issue (not sure what motor you have), this would tell you by getting 0 psi compression.

Only one thing left "timing". Are spark plugs wet with gas. The engine may be flooded.

how much fuel pressure..how much volume??.. try spraying some carb. cleaner into the intake while cranking it see if it tries to fire, if it does its still fuel related. otherwise id take it to a mechanic

If its a high mileage engine it could have jumped time due to a worn timing chain....sounds like a job for a professional... good luck

low compression or none in one or more off the cylinders off the engine. this is most likely as long as the starter is trying to crack over.

how much fuel pressure? at least 55 psi is needed. if you don't have that, it aint gonna start.
