If I turn the key on, should fuel come through the regulator then. Mine dont let throu any fuel what so ewer. Sounds like it get to much fuel and whont rev more than 7200rpm isch.

How did you check this? Disconnect the fuel rail from the injectors? You should check actual fuel pressure. Do you hear the fuel pump prime when you turn the key to run?

I diconnect the line to tank and nothing comes out. Have change the pump, tps, sparks, coils, ECU, injctors and chekt all the wiering and conectors. no codes in the display. Pull the hose to the MCX that give more fuel to the extra injctors and it run a little bit better maybe upp to 8500rpm but still sputtering.

I don't have the manual in front of me but I'd check the fuel pressure. Sounds like the FPR is not regulating properly and not bleeding off excess pressure back to the tank. Too much fuel being injected would be explained by that excess pressure.
