95 Ram cranks, won't start.

[Rambo95]

My 95 Ram 1500 5.2l out of nowhere will not start. It cranks but will not turn over. Tried new coil, coil wire cap and rotor, nothing has helped added dry gas, fuel injector cleaner and 5 gallons fresh gas to a littlle over 1/2 tank. Still nothing. Fuel pump comes on when I turn the key to on but won't start. Not sure if spark or fuel related.
