...speed when I push the Gas? what can the problem be ??? I already replaced the fuel pump.

you need a little bit more detail, when you press on the gas does it kick and sputter? does it stall? Or is this while you are already moving or sitting still? It could be a number of things, timing, bad spark plugs and wires, cap and rotor, clogged air filter, even a bad O2 sensor if it has the true Fuel Injection.
