fuel pump probley bad ck fuel pressure

P2068 indicates 'Fuel Level Sensor 2 Circuit High".
U1417 indicates "Implausible Left Wheel Distance Signal Received
Obviously the first item applies - the second relates to an ABS system issue - any ABS light on? We'll leave that one for now.
For P2068, you either have a wiring issue or a fuel level sensor issue. You could also have an instrument cluster issue, but it seems to me having this code plus having a no-start situation, you have a wiring issue at the pump. Did your pump come with a new sending unit? If not, you need to replace that as well. Check the wiring carefully at the connectors to make sure there is no damage and that all pins fit properly. Beyond that, good circuit testing is in order to find out where the short or open is.
Good luck - sounds like a challenge!

i tryed a new pump with a new fuel sensor built into it got the same thing. what i did notice is both fuel pump are coming on in going off after a few second ,there has gotta to be a short or a bad computer because i lifted up the floater arm on the old and new pump to see if it would read "full" it wouldn't it would go very slow to about half way mark .well what's going on is something kick on the fuel light then the gas hand lose function fall behind E then the car just turn over with out starting, one time it did this then after 30 or more min. i tryed again in the gas light was off and it started up .but after driving the same thing happen and now the light staying on, all these happen after i put new rims on the car mybe that the 1417 code ,do you think my "pcm" is causing the problems

The rims are absolutely causing the U1417 code.
But the no start has nothing to do with your rims. There must be a wiring issue if you say you have changed the pump and sending unit.
Incidentally, when you move the float on the pump, the gauge should not react quickly at all. Consider this: as you drive, the fuel in your tank is always sloshing around. The fuel movement causes the float to be moving constantly. Your gauge, however, stays steady. This is intentional.
Wiring concerns are not terribly common, which is why I always lean towards the component not being right. Double check the connectors and the components. Make sure the pump and sending unit are new.
After all this you will need specific testing with a good shop to help you out tracing wires, etc. Good luck!
