Fuel Gauge Problems,ez stuff done
Gauge will go to full on fill up the drop to empty after a few miles later,then moves to 3/4 tank after 200-300 miles
changed both sending units,flashed PCM,all grounds are good
There is no 5 volt signal at the right sending unit connector
checked Blue pcm connector for 5 volts at PCM pin 12 nothing. pin 10 has 5.06 v
I am sure I am looking at PCM replacement but just want to make sure I am not missing something
Thanks to all .this vette is kinda of a challenge for a Mopar guy!!!!!!

I had a similar problem last night. It all started with detonation under full throttle, so I start using fuel that is only Tier One, one tank of BP and one tank of Shell. Immediately after filling up with Shell my gas gauge went bonkers. Today it was back to normal.
I have used Techron Fuel System Cleaner twice per year prior.
