My truck went into limp mode yesterday and luckily I was near an auto parts store. They read the codes for me and P2146 and P0206 are what came up. Both seem to include a wiring/electrical problem with the fuel injectors. Anybody else had this problem or can any one point me in the right direction as to what to start looking for? Any help is much appreciated!
LB7 Codes P2146 and P0206

Hmmm never seen that on a LB7 but yes on an LLY and usually its the connector but since its an lb7 I'd be looking at the harness outside the valve covers and maybe the area close to the FICM bracket. I have seen those codes on a rig that the FICM failed also.
