I bought a Cadillac, used. Its is a 2005 cts v model, its has about 148,000 miles. I had to to replace the fuel pump. I am happy to be in the group and I hope I can find answers.
Note that there was a recall on the fuel pump wiring, so if that recall wasn't done on your car already, you might be able to have the dealer do that and replace the pump itself while they're in there.
