Question Help wth Fuel Gauge (that works sometimes)

Greetings Ė

Does anyone have experience with a D90 (97) Fuel Gauge? Iíve got a wild one. It bounces from true level to empty and anywhere in between at random (a problem even on the highway). Iíd like to fix it but I donít want to have to drop the tank to look over the sending unit if I donít have to.

Unfortunately Iím not familiar with the system. Could it just be a bad ground someplace Ė maybe somebody has had a similar problem.

Thanks

Hey Molinator, Search doesn't show anything else on this problem. How 'bout whipping out some of your Ninja powers and help your bruddas out?

What causes the erratic fuel indications? Is it the gauge or the sensor?

I would also guess that the problem has to do with the sender in the tank and the way the tank is, mine is very affected by movement in any direction so when fuel gets sloshed around the sender does not read correctly.

Thanks Mike. My latest problem is not the sloshing around of fuel in the tank causing erratic fuel level indications, but the fuel guage not indication correctly at any fuel level. I filled up and the highest the guage got was 1/3 full. It's been degrading slowly over the past month or so, and I'm wondering if I need to replace the gauge or the in-tank sensor.

How can I check if the gauge is getting a proper signal?

Well at lest he is bringing his truck, and if you bring yours then we'll have a source for spare parts.

Ken, have you checked that the connectors on the back of the gauge are clean?

Mike, gimme a LITTLE credit... haha... yes, the connectors checked and the fusebox too Oh, and I checked the tire pressure too; it's ok so that probably isn't causing the problem.

Check resistance (or would it be voltage) at the indicator? Would that be a good check for gauge health?

Good thought! I'll have too pull mine out and check what the voltage is when the tank is full and empty, then you can compare it to yours! If it reads lower then mine when full I would check for bad wiring before dropping the tank.
