Any idea where to start ? Injecters , fuel pump ?

I already cleaned the MAF sensor and has a new cat with O2 sensors. Please any advice on what to do next would be greatly appreciated.

Electrical ? Relays , fuses ? I replaced catalytic Converter and all 3 Oxgen Sensors.

Is my rear differential out ? Im spinning my back wheels but the drive shaft isn't turning l, looks like it wants too.
