Just because you hear the pump come on does not mean it is pumping the correct fuel pressure for the vehicle to start. Have fuel pressure tested. If checks out ok maybe no power going to injectors. Test for power with a noid light.

Pressure should be 56 to 63 lbs at the schrader valve on the intake manifold.
