I happen to have the air suspension option on my truck, but Im wondering if this is in fact the fuel pump spinning up and not the air compressor? It normally wont let me adjust ride height unless the engine is started and doors are closed. Also, I dont see the truck moving up or down at all, and I doubt the computer would let the air comp activate without the fob in range and the Accessory button ON....further, most cars' fuel pumps routinely do the Ironman whine when opening a door. I guess Im wondering if I have a faulty fuel pump.
