There should be a grey plug just under the master cylinder disconnect it and turn on the ignition if the gauge reads full the problem is the sending unit in the tank (thats if the gauge was reading empty before). You can also check the sending unit by using an ohm meter and checking for 22.5 ohms at empty and 145 ohms at full the wires are the yellow/white and black/yellow that are coming from the grey plug I was talking about earlier. If the sending unit does not read in limits you will need to drop the tank and replace the sending unit that is connected to the fuel pump in the tank.
It could be the fuse, but mine is because the floater that measures for the gauge is stuck.
If its Fuel Injection U put a FI pressure gauge on the Fuel Rail.
Bad dash ground.
In a 1993 Ford Ranger : Yes , all engine sizes are fuel injected
I would check the ground on the fuel sending unit
According to my Chilton repair manual , fuse # 16 is a 15 amp fuse for the fuel gauge on a 1994 Ford Ranger
The ranger has a fuel sending unit inside the gas tank. These are notorious for going out. Only way to change it is to drain and drop the gas tank or remove the bed. The sending units that I have been looking at cost about $100
No , the engines in a 1993 Ford Ranger are fuel injected ( at least they are in North America )
fuel sending unit is bad.
Inside the fuel tank combined with the fuel gauge sending unit
The engines in a 1993 Ford Ranger are fuel injected , so there is no carburetor
