The tank full light blinking won't let unit start but tank is empty any suggestions.

SOURCE: 1966 Ford Mustang Gas Guage not working

I had a similar problem. In my 1966 Mustang gas tank, the fuel pick-up was on a "float." My float developed a hole, filled with gasoline, and sank to the bottom of the tank, therefore, the gauge always read empty, but the car ran well. All the other gauges of course worked correctly. The repair was a relatively simple soldering job (after removing the float from the tank), but if that is indeed the problem, ensure all the gasoline is drained from the float before beginning the soldering job.

SOURCE: Full tank-fuel gague registers empty-need fuel light is on

There is a sending unit in the fuel tank that registers how much fuel there is. It is probably broken, giving you a funny reading on your gauge.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.
