Have a helper get underneath and listen to the fuel pump while you turn key on-is it humming? If so -check the fuel pressure and injector pulses

I have checked the fuel pump and it has the proper amount of pressure. could it be the main relay or something electrical

Are the injectors opening and closing? If so -look for ignition spark

You said the fuel pressure is good-again are the injectors pulsing meaning being snchronized by the computer providing fuel into the cylinders
