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.
If its Fuel Injection U put a FI pressure gauge on the Fuel Rail.
It could be the fuse, but mine is because the floater that measures for the gauge is stuck.
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 )
The Ranger fuel gauge could have several problems causing it not to work. These problems include, blown fuse, bad wiring, loose connections, or a bad fuel sending unit in the fuel tank.
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
Usually the fuel level sensor in the fuel pump. ANSWER A 1993 Ford Explorer also has a 15 amp fuse in location # 17 for the fuel gauge
Attach a fuel pressure gauge to the service port on the fuel rail.
I believe there is one at the fuel pickup in the pump...
It has both.
MORE THAT LIKELY FLOAT HAS HOLE IN IT AND SANK. FLOATS ARE AVAILIBLE AT YOU LOCAL FORD DEALER SEPARATE FROM PUMP.
There is a float ball in your gas tank that tells the guage what to say. The odds are it is either stuck or has a hole.
The fuel gauge could be getting improper signals from the fuel sensor. The sensor is located inside of the fuel tank.
check your fuel bypass or fuel regulater
The fuel pump is located inside the fuel tank.
in the tank
possible bad ground
fuel sending relay is bad.
