Question about 1998 Oldsmobile Silhouette

1 Answer

I have a 98 3.4 oldsmobile Silhouett just replaced fuel leveler sending unit with fuel pump fuel leveler wasn't working before and it still does not show how much fuel it has goes up when you start it then it goes to empty after about a minute or two. If the throttle position is bad would this possibly cause the problem or do I have a bad P.C.M. .

You need to make sure all your wiring is good especially the terminals in the connectors.Check all the wiring from the front to the back where the connectors hook up.If you know someone with a scanner then you can usually do a sweep test on the gauge and it should show the level reading also.But not all scanners have this ability.If it shows the level reading on the scanner then this would eliminate the pcm.Because it is seeing the data.Throttle position has nothing to do with fuel level.Do you think you have a problem with the throttle position?

Gas gauge staying at empty when tank is full


Spencer, Check all fuses ,plugs and grounding at the tank.The sending unit module, inside the GM's gas tanks were notorious for going bad in this err, when you changed it did you use a quality part? Also the fuel pump sending unit plug/wire harnesses were known issues, so much that replacement pumps would often come with replacement plug to splice into existing harness. Check the attached links,instruction and guides on how to trouble shoot fuel gauge/sending unit, Good luck

Where is the Fuel sensor locate on a 98 chev blazer?


Both the fuel level sensor/sending unit and the fuel tank pressure sensor are located on or in the fuel pump module.

The fuel tank will need to be lowered in order to gain access to the fuel tank pressure sensor which will be the black sensor on top of the fuel pump module.

The fuel tank will need to be removed in order to remove the fuel pump module to gain access to the fuel level sending unit attached to the side of the fuel pump module.

97 Silhouette Fuel guage not working correctly


drop fuel tank. if guage moves all around its probably the fuel level sensor on fuel pump assembly in the fuel tank. If the guage stay's in one spot its the guage , replace instrument cluster assembly. you can take just the glass off the cluster and move the fuel guage needle and it will work (if stuck) but for how long? The wires to the guage come from the sending unit to the power train control module to the instrument cluster. pray its not in the wiring.
