1999 Chevy Suburban V8 Four Wheel Drive Automatic 130000 miles

99 suburban gas gauge didnt work when I bought it. The fuel pump went out a little over a year ago so I replaced it. Then the gas gauge worked. Well now it doesnt work again! Any ideas?

Do you

GM had a problem with those tanks and it was found that the harness was bad and cause fuel pumps to go out. It can be a bad connection or just a bad sending unit. If you hae power to the sending unit( low voltage blinking light) then the problem is the sending unit itself.
