96 or 97? 97 went to 1500 series and 96 was G20
There is a circuit that runs from the gauge to the fuel sender in the tank. If that circuit (purple wire) is grounding out anywhere between the gauge and sender card, the fuel gauge will read full when the ignition is on. Unplug the connector for the sender and see if the gauge goes down. If it doesn't go to E, you need to find the short to ground. If it does go E, you have a problem in the tank.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
