Fuel, air, spark.... is the air filter stopped up? when the last time you changed the fuel filter? even tho the pump primes doesn't mean it is getting to the cylinders...

Does it hesitate to start? Maybe a TPS? is it flooded? FRP? a lot of variables - more details will yield a better answer.

Got gas in the tank, crank on it then check the plugs for fuel and put a timing light on it while cranking to see if it is getting fire. Press the schrader valve on the injector manifold and see if there is pressure just because you hear the pump it dont mean there is fuel pressure check the vacuum line to the regulator sniff it for fuel and pull the dipstick and smell for fuel. How old are the plug wires, plugs, cap and rotor if you have them. Check all the basics compression timing and fuel pressure for it to just die it could be something simple if it was running good prior.
