Check to see if you have fire or spark, try spraying some engine starter fluid in the intake to see if it fires for a second if so you have fire just not fuel, which could be any related reason to fuel, pump, pump relay, computer, fuses ect, if it did not fire off for a few seconds then it does not have fire to spark plugs also or just not firing, which can be computer, crank & cam sensors, coils, wiring bad , fuses, may also be low battery power you did not say if its turning over or not. Which could be bad connections to battery or starter or frame grounds, and alternator or its wiring or fuses/relays, ignition switch so basically you need to do some testing.
More than likely you have a fuel pressure issue. Spray some starting fluid into the throttle body to see if it fires up. If it does then more than likely the fuel pump is bad. Verify with a fuel pressure gauge.
