Question about 1989 Pontiac Firebird
There's several ways to check the pump and none are really difficult. First, make sure the car radio is off and there is no loud background sounds. Turn the key to the ON position, but don't crank the motor. There should be a humming sound coming from the gas tank. The hum is only about 2 or 3 seconds long, so be ready to listen.
If there is no hum, check the fuse under the dash. It's labeled "FP/INJ2" If the fuse is not blown, check the fuel pressure valve on the intake manifold. It's located under the injection plant towards the back of the manifold. Have someone crank the engine as you operate the valve.
If there is no fuel there, there is an inline fuse located SOMEWHERE under the body of the car. If the pump gets too hot, it will blow to save a potential fire. (I discovered too late that the in tank pumps can overheat if they are not submersed in gas. Keep the tank over 1/4 tank to make sure this doesn't happen)
If all fuses are good, but the pump doesn't hum, the pump is dead.
I hope this helps you out.
