I'm working on the same issue with an 01 Jimmy. Went to parts store and they pulled one off the shelf. I measured the new one with an ohm meter 38 ohms full, 247 ohms empty.

Took the guess work out of what the readings should be, other GM makes & models have different resistance, I would assume *** products might be the same. Parts stores are fairly easy to work with and should let you make a measurement of a new one for reference

Why won't the fuel gauge work?


The power wire from the sending unit runs to the gauge. Since it is showing 3/4 all the time. It is a break in the wire or really high resistance. I would check resistance of the ground wire first. If it is good(less than 5.0 ohms), I would replace the power wire from the pump to the gauge. I assume the gauge goes to empty with the key off. If not the gauge is bad.

Why will my gas gage stay at full on my 2001 excursion


The gauge is faulty or the sending unit in the fuel tank is bad ! There is away to test it, find a wiring diagram an locate the two wires at the fuel pump sending unit connector . Go to radio shack or some other electronics store an buy some resistors of differing resistance , I'm not sure of resistor sizes , I will look it up on my ford service info system. If you jump the right resisters into the fuel sending unit circuit you can make the gauge show 1/4 - 1/2 - 3/4 an full. If it move to those positions with the right size resistors it's not the gauge but the sending unit in the gas tank ! Diagnosis of Stuck Fuel Gauge Is it Gauge or Sending Unit

Fix my fuel gauge on my 2006 Ford F 350 diesel


Are you ready to pull a fuel tank ? Inside the fuel tank is the fuel sending unit.The instrument cluster is hardwired to the fuel sending unit, which is a variable resistor controlled by the action of a float arm. When the fuel level is low, resistance in the unit is low. When the fuel level is high, the resistance is high. The instrument cluster uses the input from the fuel sender and commands the fuel gauge indication according to the fuel level data. Do you know anything about automotive electrical systems ? Do you own a volt meter and do you know about code setting capability potential in new vehicles ? It is possibly for a problem in the fuel sending unit circuit to set codes in the smart junction box.

Wiring diagram of fuel gauge for toyota corolla 2006 - frozen fuel gauge


It is the sending unit, usually the veryable resister and arm. Remove and replace sending unit. It is , unfortunately, located inside of the fuel tank. To confirm gage operation reverse wiring to the guage and it will reverse the guage, confirming tha the gauge.is ok.

1984 FIERO 4 CYL STICK. had a aftermarket elec temp gauge mounted on console, replaced with a mech temp gauge. after replacing temp gauge is when the fuel gauge messed up. now when you turn on the key or...


I assume you replaced the temperature sending unit when you installed the aftermarket gauge? You need to put the proper sending unit back in for the OEM gauge to work.

You can find a sending unit here (and a gauge if needed):

Gas guage doesnt work


It sounds like a problem with the fuel gauge sender unit in the fuel tank which has worn out and gone open circuit and needs replacing. Access to the unit is usually through a removable plate in the floor in the rear of the vehicle. Disconnect the wiring connector and any hoses and then remove the securing screws. Replacement is done by reversing procedure.

NEED TO REPLACE FUEL PUMP FOR 1996 fORD eXPLORER, V6 4.0. WHERE IS IT AND HOW DO I GET TO IT?


Great SUV, I have the same model; for Ford Ranger/Explorer/Mountaineer 1991-1999 check this procedure to Fuel Pump - REMOVAL & INSTALLATION...
(see Figures 1, 2 and 3)

To gain access to the fuel pump, it is necessary to remove the fuel tank.
  1. Depressurize the fuel system and remove the fuel tank from the vehicle.
  2. Remove any dirt that has accumulated around the fuel pump attaching flange, to prevent it from entering the tank during service.
  3. Turn the fuel pump locking ring counterclockwise using a locking ring removal tool and remove the locking ring.
  4. Remove the fuel pump and bracket assembly.
  5. Remove the seal gasket and discard it.
To install:
  1. Put a light coating of heavy grease on a new seal ring to hold it in place during assembly. Install it in fuel tank ring groove.

Fig. 3: Fuel pump and sending unit used on the Explorer and Mountaineer
  1. Insert the fuel pump assembly into the fuel tank, then secure it in place with the locking ring. Tighten the ring until secure.
  2. Install the tank in the vehicle.
  3. Install a minimum of 10 gallons of fuel and check for leaks.
  4. Install a pressure gauge on the throttle body valve and turn the ignition ON for 3 seconds. Turn the key OFF , then repeat the key cycle five to ten times until the pressure gauge shows at least 30 psi. Reinspect for leaks at the fittings.
  5. Remove the pressure gauge. Start the engine and check for fuel leaks.

Hope help with this; remember comment and rated this help. TY for using Fixya.

Nedd to test coil on an 89 chevy 2500, dont know parameters


PICK-UP COIL (HEI)

1. Isolate 2 pick-up coil lead wires. Remove pick-up coil connector from module. Connect ohmmeter to either terminal and ground. See Fig. 4 . Connect pump and apply vacuum to test vacuum advance unit. Replace vacuum advance unit if inoperative. Connect ohmmeter to pickup coil terminals. Operate vacuum pump and observe ohmmeter throughout the vacuum range.

2. Attach ohmmeter to one pick-up coil terminal and distributor housing. Set ohmmeter to middle scale. Operate vacuum advance throughout vacuum range. Reading should be infinite at all times. If not, replace pick-up coil. See Meter "A" in Fig. 4 .

3. Connect ohmmeter leads to pick-up coil connector terminals. Operate vacuum pump to ensure proper operation throughout vacuum range. Flex terminal wires by hand to check for possible intermittent defects in wiring or connectors. Pick-up resistance should be 500-1500 ohms. If resistance is incorrect, replace pick-up coil. See Meter "B" in Fig. 4 .

NOTE: Activation of the vacuum advance may align trigger wheel tooth and pick-up coil pole piece causing ohmmeter pointer to deflect. This
deflection should not be diagnosed as a faulty pick-up coil.

Fuel gage does not work


I just fixed that problem in my 87 Toyota pick-up. My fuel gauge showed FULL all the time. The sending unit in your fuel tank has probably croaked. I had to drain the fuel tank, remove it, and try to remove the screws that hold the sending unit in. The screw heads ALL snapped off due to them being 21 years old. Ended up having to buy a new fuel tank, as we couldn't get the broken ones out of the tank. Found an aftermarket new tank for about $275 at Advance Auto. Sending unit is only avaliable from Toyota for about $125.
