Yes, there is a fuel sensor in a 2000 GMC Sierra.
yes, yes it does no, its the crappy tbi systems. tbi stands for THROTTLE BODY INJECTION! it has fuel injectors and has to be treated as such. it is not carbureted.
I own a 1990 GMC Sierra 1500 5.7L V8. My fuel filter is located along the frame rail under the cab on the driver's side of the truck. You might look there for the filter on your 1989 Sierra. It's an inline silver colored canister.
Cycle the ignition key on and off several times pausing a few seconds in the on position. This will prime the fuel injection system.
