In the fuel tank the acsess panel is under the passenger rear seat.
Assuming it is a 86-93 model bseries I will for answering this.If the gauge does not register it is more than likely the fuel sending unit in the fuel tank is BAD.To correct this requires dropping the fuel tank and replacing the fuel sending unit.You can try and ground the power wire from the harness at the tank(very difficult to do for clearance purposes) and if the you ground the power wire and it makes the gauge move to the full position the fuel sending unit is defective.I would just buy a new part and drop the tank being the truck is probably over 15 to 20 yrs old and needs a new fuel sender.I seriously doubt the gauge is bad(in most cases the sending unit is worn out in the fuel tank).Ok
To fix the fuel gauge on your 1986 Mitsubishi Mighty Max, first check the fuse related to the fuel gauge in the fuse box. If the fuse is good, inspect the wiring and connections between the fuel tank sender unit and the gauge. You may need to access the sending unit located in the fuel tank to check for any faults or corrosion. If all else seems fine, consider replacing the sending unit or the gauge itself, as one of them may be faulty.
The fuel tank sending unit in an '86 Ford Ranger typically includes a few key wires: a ground wire, a signal wire that sends fuel level information to the gauge, and sometimes a power wire for the fuel pump (if applicable). The ground wire is usually black, the signal wire is often light green or gray, and the power wire can vary by model. For an accurate wire diagram, it is recommended to refer to the vehicle's service manual or a dedicated wiring diagram resource specific to the 1986 Ford Ranger.
The location of your oil pressure sending unit is right behind your distributor. there is a spitter there with two(at least on mine) sending units. I believe the one on the passenger side is a fuel pump shut off switch (when oil pressure is too low unless you have a mechanical one) and the one on the D.S. is the oil sending unit. I have an 86 GMC Sierra and that's the way it's situated on mine. I hope everything goes well! God bless, Howie
The fault could be the sending unit or the dash gauge.
No. 85 was the last year for straight axles.
I assume you're talking about the sending unit (the part that tells the gauge on your dash how much is in the tank). It's in the gas tank. I'd check the dash gauge before going after the sending unit, since you have to drop the tank to get at it.
three hours
cooling fan relay has gone bad or coolant temp sending unit is bad
check your dip stick to see if your engine oil is too low. also check oil sending unit
Try splicing it with flexible fuel line and hose clamps
Check engine fuse!
