You need to find out if it is spark or fuel related, spray a little starter fluid down the intake and see if it wil fire up briefly, if it does then it is fuel related if it doesn't then it is spark. If it's fuel check for proper fuel pressure and if the injectors are pulsing, no or low fuel pressure could ba fuel pump or regulator, no injector signal could be a blown injection fuse, no signal from the ECM, no crank sensor signal or bad ECM. If it's spark, to see if you have spark output from the coil, cap and at the plugs, you may need a new cap, rotor and wires, if no spark anywhere you may have a faulty ignition module or a burned out coil.
