My teenager ran my 2003 Aurora out of gas and fried the fuel pump, which led to forced replacement of entire fuel pump assembly because you pretty much have to go that route. We got lucky with a used Cadillac assembly from a Pick n Pull and replaced the fried pump & its assembly with the Cadillac part. If you take on this repair yourself, make sure you CLEARLY MARK the fuel lines' attachment to the 2 longer, left & right prongs on the top of the assembly so you put them on the new part the right way. The 3rd, shorter center prong is a vent line and nothing gets put on the end of it. Make sure you replace as many gaskets as you remove or you could end up with a loose assembly that leaks gas fumes. In our case, a gasket was not replaced as it should have been when the new part was installed. This led to the fumes, then to the computer dinging & displaying CHECK GAS CAP upon every start. After about 30 of those, the CHECK ENGINE light made its appearance and stayed on constantly. Once we finally realized a gasket wasn't replaced & replaced it, we sealed the connection between the gas tank and the vehicle and drove about 4 miles, the fumes evaporated. Car was restarted a minute later, without the ding & CHECK GAS CAP warning AND the CHECK ENGINE light turned itself off!! Hallelujah. Nice to not be reminded constantly that your kid screwed up. He got to pay for the repairs from his car fund... :)
