Bought a new MU1844 GM fuel pump in April 2020 for my 2008 Suburban. Installed that spring and has about 25K miles on it.
As of this weekend, it appears to have started making noise. Twice now I've turned the key on but not yet started the vehicle, and I hear what sounds like a climate control fan running from the back underneath side of the vehicle. (The climate control is off, btw.) Truck starts and runs fine. Based on sound and location, I'm assuming this is the fuel pump.
I replaced the original pump because it was making noise and, based on going fishing in some pretty remote places, I needed it to be reliable. Thus the Genuine GM part choice...
Besides monitoring it, is there anything I can/should be doing or checking?
I'd welcome thoughts...
