2000 LeSabre Erratic Fuel Gauge
Got a good deal on this vehicle, but the intrument panel had a DIC that fuzzed out, and the fuel gauge was erratic. I replaced the IP and it fixed the DIC, but the fuel gauge was not better. When I've had that problem in the past it'* been the sender unit on the pump, so I replaced the pump....still no luck. The gauge constantly moves about---when you start it, it immediately goes to full no matter what amount is in the tank, then slowly begins to decrease, before moving back to full etc.... I've noticed that it will never go lower than the actual amount in the tank...so we can tell what amount is in the tank to watch for where it "bottoms" out. Now that we've replaced the IP, and the FP....what is left that could be causing this issue?
