Anyone with experience troubleshooting I Command gauge for fuel level ( mine always reads empty). My sending unit checks out with ohms check using multi meter. Gauge Worked for a couple of months after dealer installed new engine and had him install new sending unit at the same time. Kept the tank full all the time since. Retired now so I have the time to fix. Being cautious to not short anything out at this stage. Have been reviewing internet and utube but they only describe analog gauges. Thanks

There could be any number of things that would give the same symptoms. Most likely there is a connection problem, a faulty analog to digital converter, or the memory module if equipped.
