I have got power to both fuse compartments. I have replaced the starter, alternator, ignition, coil packs, plugs and battery. Car will crank but wont run. Also my fuel pump is good. Also all lights and instrument panel is working fine put a code reader on it but shows no codes.

This sounds like the crankshaft angle sensor has gone out which will leave no codes. when you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds? These guides should help us fix it:

Also, lets run the codes to see what come up.
