Not only is my gas gauge not working but the speedo gauge is not working either. The mileage nor the speedo gauge work. With having the issue with my gas gauge, i thought it might be the whole gauge cluster but I hooked my scanner to it and watch the live feed and it says i am always going 0 mph so my guess something is messed up between the speed sensor and the gauge cluster. Now it has been like this for awhile, since I put the new PCM in. Think there is a axle ratio or something that needs to be turned on with the starscan/DRB in the new PCM? The new PCM came from Chrysler and I had one of the guys flash it and it runs fine and all the lights work and other gauges (except fuel) work just fine. Let me know if you have any thoughts
