on the frame rail under drivers side seat area

The fuel filter should be located on the driver side frame rail underneath the cab of the truck.
Under the bed , on the rear passenger side of the fuel tank.
inside the gas tank
Look under the vehicle along the frame - follow the fuel line from the tank
Plugged catalytic converter? Air/Fuel filter? Worn plugs?
It is in the fuse panel. It is the ignition fuse that goes bad and keeps the truck from firing.
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.
