I purchased a used vehicle. At that time the gas tank was full. I drove the vehicle only 4 to 5 miles and the gas gauge was saying empty and the yellow item saying the tank was empty was showing. I filled the tank with $20.00. The next day I only drove 3 or 4 miles and the gas gauge was almost at the empty location. I when to a gas station but I could only put 4 - 5 dollars of gas in the tank. That means that the gas tank was saying empty when really it was almost full. Something is wrong.

I had to replace the entire fuel pump as this is a module. I then replaced the same unit 2 more times with the same resulte. Shop then gave up!!!! Nice.
