On my 1998 Chevy K1500 I'm working on I have around half a tank of gas, the voltage is reading 2.7V at tank and at PCM in, but only around 1.5V on the wire that runs from the PCM to the garage, but with gauge out there is nothing on the plug behind the cluster. What should the voltage be on the wire from PCM to the gauge?
