After you have checked for faulty connector at the pump and still have the same problem, perform this test by disconnecting the fuel-gage wire at the sending unit. Then turn the ignition key to the ON position to provide power to the instrument panel. With the wire unhooked and the key on, look at the fuel gage reading. If the gage is operating properly, it will read either COMPLETELY FULL or COMPLTETLY EMPTY, depending on the make and model of the car.
Next, take the end of the disconnected wire that leads to the fuel gage and connect it to a metal part on the vehicle's frame. This procedure is called" grounding the wire". While the wire is grounded, look at the fuel-gage reading. If the gage is operating properly it should read either COMPLETLY EMPTY or COMPLETLY FULL depending of the make and model of the car. However, the reading should be exactly opposite of the reading you obtained with the wire unhooked.
If the gage responds correctly during this test, the problem is in the sending unit. However, if the reading is the same, the problem is either in the wiring to the fuel gage or in the fuel gage itself.
Bring your car back to the dealer and have them check the " everything in the tank again". And have them do this test for you.
