Good afternoon yall, I'm having an issue with my 1998 Chevy K1500 A/T that I've been trying to solve for a while now that is causing my work truck to go into limp mode and also gives me intermittent codes. I went ahead and disconnected the battery aslong as most of the wire harness and took resistance readings of all the VCM wires to ground. All of my pink wires in the engine bay resistance to ground were reading 38-40Ω. My IGN-E, ECM-1, ENG-1 were all also reading the same exact thing. I went ahead and started pulling and replacing fuses to isolate where this was coming from until I pulled the "gauges" Fuse 4 in the IP fuse box. Once this fuse was pulled my pink wires were no longer reading 38-40Ω. So now I know my short is probably coming from something connected to this fuse which connects directly to the instrument cluster. I disconnected the ignition switch, still reading 38-40Ω at the Gauges fuse.
Is there a ground in my dash for the instrument cluster? Could it possibly be my fuel pump & sender being improperly grounded? Should I replace my instrument cluster?
The BRWN/WHT that connects MIL to the instrument cluster to the VCM is reading 58Ω.
The TAN wire that connects my oil pressure sensor to the Instrument cluster reads 72Ω.
