I have a '95 Ford Ranger with the 2.3 L 4 cyl.
The other day I noticed that the gas gauge read empty.
First I thought someone had siphoned my gas but when I put more in it
only took a few gallons and the gauge still reads empty.

What is the simplest diagnostic procedure I can use to determine if
the problem is the gauge, the sender or some other problem?
I do not want to drop the tank unless absolutely necessary.
All the other gauges work OK and the vehicle has no other problems.
Is there a fuse that controls the fuel gauge?

Pull the tank .. pull the fuel gauge sending unit.

You might have just lost the float, the swing bar if they use one like
that .. or the electrical sending unit.

Since your dash is working, this is isolated, it is best to check if
electricity is getting TO the SENDING UNIT.

Usually sending units only have one wire, and if that is intact and not
cut or broken .. it is usually good.

Soooo ... pull the tank is the best first bet if you wanna do it your
self and not do a proper Diagnosis and find out.

Likely it is an open circuit in the fuel pump sending unit, they can
test engine starters for being bad with this open circuit test if it is
burned out electrically.

So pull the fuel pump sending unit .. put it into a good truck and if
it makes that same break .. then it is the sending unit.

Much like testing computer parts.

Likely you might discover how it is broken once to your eye.

Plan two .. hunt down the electrical short in the wiring harness.

I don't think there is a plan three for this connundrum lacking data.

All my best,
