s10 lsx conversion problem. need help

[white96]

I am at my wits end. My project is finished but I have no throttle. All the parts are from a 2004 silverado except for the TCM module. The engine is a 4.8 v8, 2004 silverado 4.8 ecu. The throttle controll module is from a 2006 silverado. I bult the wiring harness myself. The ecu was reflashed by a friend of mine at superchips in Orlando.
The truck is a 1996 s15 jimmy.
The truck starts right up and runs perfect. I have no throttle at all. The codes I pulled are a p1125, a p2120, and a p2125. I have checked every wire. I have checked all voltages with a scan tool. I have checked voltage and resistance with a multimeter.
APP sensor 1 is .57v @ idle and 3.87 at wot
APP sensor 2 is .56v @ idle and 3.87 at wot
sensors "AGREE" according to the scan tool.
If I clear the codes they come back imediatly
my PCM service # is 12586242 and the hdw # is 12583660
the TAC module # is TM01-160K1
the # under that # is 508-018930
the APPS # is hard to read but looks like # 010504-00360-4
the only # I see on the throttle body is 13z022
is it possible that the APPS is bad? I am on my 3rd TAC module. I am desperate for answers.

what year is the pedal assembly from?

the 2006 pedals are completely different from 2005 and earlier pedal assemblies and are NOT interchnagable

Yep what Ben said, you MUST have matching throttle parts, plus the tune in the ECM must match the throttle system you have.

the only difference I have found is this..

The 2003-2005 systems were all the same. HOWEVER. In 2005 they went to a 2 pot sensor in the pedal, even though the pedal looks identical to the 2003-2004 3 pot systems. The 2006+ pedals are 2-pot as well, but they look completely different.

I know for a fact a 2003/2004 PCM (which, from the factory, worked with a 3-pot TAC/pedal system) will work 100% normally with a 2005 2-pot TAC/pedal. I dont know about 2006/2007.

if that makes sense.
