digital guages

The speedo and tach work fine, the issue it the gas gauge and odometer. The odometer flashes 999999.9 constantly and fuel gauge doesnt work at all. Any chance i can get some pointers on a fix?

Re: digital guages

Also, its odd but when i just set the key to power (not actually start the motor) the oil pressure gauge, temp gauge and battery gauge "work", but as soon as i fire the motor, they go dark...any ideas?
