The day before, I filled my tank. Next day the empty gas light was blinking and the fuel level was on low. Below the empty line. So I had decided to pick a used fuel pump assembly with the fuel level sending unit attached at my local salvage yard. Took off the rear seats and first unplugged the fuel pump. Then what I did was plugged it into the one I got from the salvage yard. I then put it on to the on position. And still the same level. Empty with the gas low light blinking. I then checked the wiring with signals with an ohm meter. Both of the fuel pump readings signaled the same. Both had no loose wires or corrosion. I’m thinking both the fuel level sending unit is not the problem. Could it be a gauge problem within the instrument cluster? Keep in mind, I did not fully install the fuel pump that I got from salvage yard. Just did a test first. Thanks, hopefully someone had experience with this.
