I have had this car completely apart and rebuilt the 5.7l engine with a 6.1l stroker rotating assembly. The car will start and run although you have to give it just a little gas to get it to start almost like its getting air in the fuel line and takes a second to fire. Then it has all the lights above on the dash are on. The engine light is not on and no engine codes are present. The only codes I find under body control module is a U1108 additional can b ecu detected and under anti lock braking systems a C121A steering angle sensor not initialized and U140E implausible vehicle configuration data received. It also has a lost communication with radio code but it has an aftermarket stereo now so im sure thats why thats there. Any help or direction would be greatly appreciate, thanks.
