Issue: Fuel Gauge Stuck on Full after Premium Cluster Upgrade

[DoctorGreeny]

Hi everyone,

First off I want to say this is my first post on the forums(yay!) after using it for general DIY stuff.

Now, as the title suggests I just finished installing Premium 7” Instrument Cluster into my truck. Everything is working correctly except the fuel gauge.

The fuel gauge is stuck on reading as full, the estimated range is also displaying the range at 100% fuel capacity. MPG estimates seem to be unaffected and appear to be reporting correctly.

I’ve looked for info online and on these forums, but all I can find are problems where people have replaced parts of the fuel system and had issues pop up.

I’ve updated all of the info (odo, idle, drive hours, set the VIN) for my new cluster to match everything on the old cluster. Did a cluster self-test and still running into the issue. I ran into no issues using AlfaOBD.

I could really use some help on this issue before I remove it and replace the old cluster.

Have you driven the truck since the evic install? It may need to have the float assembly on the fuel pump cycle the fuel level info.

Since installing it I’ve driven it about 20 miles and still have the issue

I should have mentioned in my original post that I used an OBD scanner to give me the fuel readouts as I drove it and it was giving me the correct readings.

Try running a few cycles, on off run for maybe 20 minutes each time. See if that gets it to reset.

No change after 3 cycles. Will continue to drive (had a full tank and will monitor with obd2 scanner) for a few days to see if it ever resets itself. In the meantime I’m open to trying other things for a possible solution.

You can connect to the instrument panel directly in AlfaOBD and see if resetting the ECU or running a self test corrects the issue.

Good news, after about 80 miles the fuel gauge started working after an off on cycle.
