Replacing a fuel pump on a 1992 Corvette is a moderately complicated job. The fuel pump is located inside the fuel tank, submerged in liquid, and is responsible for ensuring that pressurised gasoline flows to the engine. To replace the fuel pump, a mechanic will need to access the failed pump through the top of the fuel tank, either via an access panel in the passenger compartment or by removing the tank from the vehicle. This is best performed at a dealership's service department or a service centre that works on Chevrolet vehicles.

How to test the fuel pump
Replacing a fuel pump on a 1992 Corvette is a moderately complicated job. The fuel pump is located inside the fuel tank, submerged in liquid, and is best replaced by a professional mechanic. However, there are a few ways to test the fuel pump to see if it needs replacing.
Firstly, turn the key to the run position and listen for any buzzing coming from the fuel pump. If there is no sound, this could indicate that the pump is not working. Next, set the amperage on a voltage meter and place the clamp on the positive wire to the pump. Then, start the vehicle and record the amperage reading, comparing it to the manufacturer’s specifications. If the pump did not turn on, remove the electrical connector and set the DC volts on the meter. Place the positive meter lead on the terminal of the positive wire in the connector and the negative meter lead on the terminal of the negative wire. Finally, turn the key to the run position again and check the voltage reading. If it is the same as the battery voltage, then the pump has failed and will need to be replaced.
Alternatively, to get the fuel pump to run continuously without the car running, you can jumper across two terminals of the fuel pump relay under the hood in the fuse box. Turn the ignition to the start position (without cranking the motor over) and let the fuel pump run the driver's side tank dry.
If you suspect that your fuel pump is failing, it is recommended to take your car to a service centre that works on Chevrolet vehicles and have them diagnose the problem. Signs of fuel pump failure include a car that won't start or stalls once it has started, a slowly starving fuel flow causing the check engine light to come on, or a whirring sound coming from the fuel tank.

How to access the fuel pump
Replacing the fuel pump on a 1992 Corvette is a moderately complicated job, best performed by a professional mechanic. The fuel pump is located inside the fuel tank, submerged in liquid, and is accessed through an access panel in the passenger compartment or by removing the tank from the vehicle.
To access the fuel pump, you will need to locate the access panel in the passenger compartment. This is usually found in the rear of the vehicle, near the fuel tank. Once you have located the access panel, you will need to remove any necessary trim or panels to gain access to the fuel pump.
If the fuel pump is not accessible through the access panel, you may need to remove the fuel tank from the vehicle. This will require additional tools and safety precautions, as you will be working with flammable liquids and gases. Be sure to refer to a repair manual or seek professional assistance if you are unsure about any part of this process.
Before attempting any repairs or maintenance on your fuel pump, it is important to first diagnose the problem. There are a few signs that may indicate a failing fuel pump, including a car that won't start or stalls once it has started. Additionally, you can perform a voltage test to determine if the pump is receiving power. To do this, set the amperage on a voltage meter and place the clamp on the positive wire to the pump. Then, start the vehicle and record the amperage reading, comparing it to the manufacturer's specifications. If the pump did not turn on, remove the electrical connector and perform another voltage test.

Where to take your car for a replacement
Replacing a fuel pump on a 1992 Corvette is a moderately complicated job. It is best to take your car to a service centre that works on Chevrolet vehicles, such as your dealership's service department. A mechanic will need to get to the failed pump through the top of the fuel tank via an access panel in the passenger compartment or by removing the tank from the vehicle.
If you want to try to fix the pump yourself, you can test it by turning the key to the run position and listening for any buzzing coming from the fuel pump. If there is no sound, you can set the amperage on a voltage meter and place the clamp on the positive wire to the pump. Then, start the vehicle and record the amperage reading, comparing it to the manufacturer's specifications. If the pump did not turn on, remove the electrical connector on the pump and set the DC volts on the meter. Place the positive meter lead on the terminal of the positive wire in the connector and the negative meter lead on the terminal of the negative wire. Turn the key to the run position, and if the voltage reading is the same as the battery voltage, then the pump has failed.
However, it is recommended that you ask a technician to do the test or replacement.

How to run the fuel pump without the car running
To replace the fuel pump on a 1992 Corvette, a mechanic will need to access the failed pump through the top of the fuel tank, either via an access panel in the passenger compartment or by removing the tank from the vehicle. This is a moderately complicated job, so it's best to take your car to a service centre that works on Chevrolet vehicles.
To run the fuel pump without the car running, you will need to jumper across two terminals of the fuel pump relay under the hood in the fuse box. The pump relay is #55 in the fuse box. Once you've done this, turn the ignition to the start position (don't crank the motor over) and let the fuel pump run the driver's side tank dry.
Alternatively, you can try the following steps to test the fuel pump:
- Turn the key to the run position and listen for any buzzing coming from the fuel pump. If you don't hear anything, proceed to step 5.
- Set the amperage on the voltage meter and place the clamp on the positive wire to the pump.
- Start the vehicle and record the amperage reading. Then, compare the reading to the manufacturer’s specifications.
- If the pump did not turn on at all, remove the electrical connector on the pump.
- Set DC volts on the meter, place the positive meter lead on the terminal of the positive wire in the connector and the negative meter lead on the terminal of the negative wire.
- Turn the key to the run position, and if the voltage reading is the same as the battery voltage, then the pump has failed.
Please note that these steps are for reference only, and it is recommended that you ask a technician to do the test or replacement.

How to know if your fuel pump is failing
Replacing a fuel pump on a 1992 Corvette is a moderately complicated job that is best performed at a dealership's service department. However, there are some ways to tell if your fuel pump is failing.
Firstly, if your car is not getting enough vacuum, it may not be able to start, or it may run very poorly. Your engine may sputter or misfire frequently, and you may notice a loss of power. If your engine is stalling or running rough, this could be due to a failing fuel pump.
Another sign is if your car won't start or stalls once it has started. The fuel flow can slowly become starved, causing the check engine light to come on. If you hear a whirring sound coming from your fuel tank, the fuel pump may be about to fail, as they do not normally make noise.
You can also try the following: turn the key to the run position and listen for any buzzing coming from the fuel pump. If there is no sound, set the amperage on a voltage meter and place the clamp on the positive wire to the pump. Start the vehicle and record the amperage reading, then compare it to the manufacturer's specifications. If the pump did not turn on at all, remove the electrical connector on the pump. Set DC volts on the meter, place the positive meter lead on the terminal of the positive wire in the connector, and the negative meter lead on the terminal of the negative wire. Turn the key to the run position, and if the voltage reading is the same as the battery voltage, then the pump has failed.
If you suspect your fuel pump is failing, it is important to take your vehicle to a mechanic to have it diagnosed and repaired.
