If the gauge failed immediately after the pump repair it is a good assumption you had affected the fuel tank sending unit. It would appear the float is stuck @ 3/4 tank. From my vantage point I expect you'll need to get back in to the tank to correct.
I hope this may have helped,
Tom

there maybe a switch between the two tanks ,it must be replaced by a new one,to let the fuel on the other tank pass into the fuel pump.

Replaced fuel pump now fuel gauge isn't working


sending units get knocked out of calibration when they change the pump.(carelessly).if you can.. check the top of the tank, to see if they plugged it in firmly. if not, raise heck till the change it. (doubt they will). other than the wires, not much you can do, without dropping the tank.

This problem in a Ford is caused by a defective fuel gauge sending unit inside the fuel tank, the tank must be removed to replace the sending unit.

The fuel gauge shows 1/4 tank with 115 miles left until empty but the car stopped due to no fuel.


Bring it back to dealer and them recalibrate computer and fuel gauge. Someone missed that in new car prep

Where is the fuel pump located in a 1985 fiero


from autozone.com:

The Fiero is equipped with a electric fuel pump and gauge sending unit mounted in the fuel tank. The pump is serviced and a complete unit by removing the fuel tank.
REMOVAL & INSTALLATION

CAUTION To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing any fuel system component. If this procedure is not performed, fuel may be sprayed out of the connection under pressure. Always keep a dry chemical (Class B) fire extinguisher near the work area.

  1. Disconnect the negative (-) battery cable.
  2. Relieve the fuel system pressure.

Remove the fuel pump fuse from the fuse block located in the passenger compartment. Start the engine and run until the engine stops due to the lack of fuel. Crank the engine for 3 seconds to ensure all pressure is relieved.
  1. Drain all the fuel from the tank using a suction pump.
  2. Raise the vehicle and support with jackstands.
  3. Disconnect the wiring from the tank.
  4. Remove the ground wire retaining screw from under the body.
  5. Disconnect all hoses and filler neck from the tank.
  6. Support the tank on a jack and remove the retaining strap nuts.
  7. Lower the tank enough to disconnect the fuel sending unit wires.
  8. Disconnect the fuel line, vapor line and return line.
  9. Remove the tank from the vehicle.
  10. Remove the fuel gauge/pump retaining ring by turning the cam lock ring counterclockwise using a spanner wrench such as tool J-24187.
  11. Remove the gauge unit and the pump.

To install:
  1. Inspect the fuel pump attaching hose for any signs of deterioration and replace if necessary. Also, check the rubber sound insulator at the bottom of the pump.
  2. Push the fuel pump assembly into the attaching hose.
  3. Using a new O-ring seal, install the pump assembly into the tank.
  4. Install the cam lock ring over the pump and lock by turning clockwise with a spanner wrench J-24187 or equivalent.
  5. Support the tank on a suitable jack.
  6. Raise the tank enough to connect all fuel and filler hoses.
  7. Connect all electrical wires to the pump and tank.
  8. Raise the tank and install the retaining strap nuts. Use new sound reducing pad if they are damaged. Check all connections and wire to ensure proper installation before refilling the tank.
  9. Refill the tank with unleaded fuel. Reconnect the negative (-) battery cable.
  10. Start the engine and check for fuel leaks and gauge operation.

Low fuel light comes on at idle. Yes, there is a 3/4 to full tank. Idles fine at stops and has excelleration.


Hi, A common problem with these trucks is the sending unit mounted on the fuel pump in the tank. The sending unit is a variable resister which tells the gauge how much fuel is in the tank. this resister is not made very well, my sending unit failed after 5 years. I waited till my fuel pump failed(2 years later) replaced the pump now my gauge works great.

Smog test will not pass


This code is send (in your case NOT SEND)
by the fuel sending unit.

Does your fuel gauge give incorrect of jumpy reading when it's full?

The quick fix is STOP TOPPING OFF the fuel tank when you are get gas.

Keep topping off will push the fuel tank float off it's sensor limit and eventually short or send OUT OF RANGE reading to the fuel gauge.

Fill your truck up to 3/4 tank full.

Drive it for 2-3 days or about 100 miles.
(this will fill the ready-ness data that DMV want)

If there is NO check engine light ON during the 2-3 days then give the smog test another shot.

DO NOT add fuel unit you complete the smog test.
===

The CORRECT method to fix your problem is to drop the gas tank and replace the fuel sending unit.

If you truck has over 140,000 miles on it then I will recommend you the change the WHOLE integrated fuel pump/fuel sending unit and fuel filter at the same time.

Gas Gauge or Sending Unit


more than likely it's the gauge it sets in a circuit board and sometimes the contacts get worn and with vibration it voltage spikes it and then it fails. very seldom is it the sending unit in the tank. please rate this...thanks
