As for the communication code... would that be because it is a L67 pcm in the car?

OK... then we need to start working on this.
As for the fuel module code... How would we go about fixing that. We would need a L67 pump and that module?
And how the hang are we going to go about the pcm communication code?

Umm.. good question.
When my uncle scanend it with his code reader he only got an Evap code. He cleared it and we drove about 25 miles and it came back.
Today my brother got on a Snap On scan tool, he got all those codes. They were cleared but said that the SES light came back on after like 10 miles.
I would have to have him get back on the tool (maybe tomorrow) and see if the same codes are back.

I would guess that the communication error is coming from the PCM'* inability to communicate with the fuel pump control module. This is the diagram...
The description.....The L67 supercharged engine utilizes a 2-speed fuel pump control module. The fuel pump control module is located on the wheel house flange in the trunk. The fuel pump control module controls the fuel pump output depending on the MAP sensor input received by the PCM.

The control module is in the trunk area in the RR fender area. You'd need that module, and associated wiring leading to the PCM. I doubt this would set a light, however so, the only way one would know there was a problem would be if the had a reader or scanner capable of reading the U codes. Your light is probably associated with the evap code.

That PM was to me. I never ran into this problem. What PCM are you running? Was it programmed correctly for the correct VIN and what year are you running? There were some issues with the 2000 program and it has to be specific to the SSEi. I ended up replacing the fuel pump and canister, but that was for a different reason about a year and a half later.

Reading some of the information on the diagnostic information for each code at the links I posted above shows that U1000 is set when communication is lost with a module, and to check for other codes that would be associated with a module. The only one there is for the fuel pump relay control circuit, and likely because the module isn't there. So, those two codes would seem to be related.
