Where is the fuel pump located?
The end of the fuel pump relay is typically located near the center of the floorboard, under the carpet in the front section of the passenger’s or driver’s side footwell.
What does a fuel pump relay look like?
The fuel-pump relay is a small unit, typically enclosed in a plastic case. The unit contains several sprockets on one side that are clipped onto the ignition system.
What should I do if my fuel pump is not working?
You should feel a “click” every time you switch the ignition. If the fuel-pump relay is not working, you can “jump” the unit with a small lead jumper cable. You will need to access the fuse panel and insert the cable into the relay unit; the unit will run as long as the wire is inside the relay and can help start your car.
Where are the relays located in the fuel injection system?
Two relays are located inside the fuel-injection system; one of them is responsible for turning the ignition on without turning over the engine, and the other is responsible for turning on when the engine turns. You can check to see if the first relay is working by touching it while turning the ignition on and off.
Where is the universal fuel pump on a car?
A universal electric fuel pump can usually be mounted to the frame and wired to your ignition circuit to pressurize the fuel system as soon as you turn your key. This helps your vehicle start more quickly than relying on a mechanical fuel pump operated by turning the engine over.

How do you change the fuel pump on a Camaro?
First, pull the fuel pump fuse and disconnect the negative (black) battery terminal. Also, bleed the fuel pressure at the Schrader valve on the driver’s side fuel rail. Make sure you have a bucket and rags ready for this. Lastly, open the gas cap to relieve any more pressure. Now, you can proceed to cut the trap door as shown in Figure 3.
Where is the test point for a fuel pump?
Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.
How does the fuel pump relay work in a Camaro?
The fuel pump relay in a Chevrolet Camaro provides power to the fuel pump. The powertrain control module, or PCM, controls the fuel pump relay. When the PCM decides to turn the fuel pump on, it energizes the fuel pump relay and the relay’s internal circuitry closes and completes the electrical circuit.
How can I bypass the fuel pump relay?
When the relay fails, the fuel pump won’t operate. A small length of copper wire can bypass the fuel pump relay inside the relay fuse block in order to operate the fuel pump for testing purposes. Park the vehicle on a flat surface and open the hood. Locate the under-hood relay center.
When do you need to replace the fuel pump?
However, when you start modifying your car or have high miles, you will have to replace your fuel pump. The fuel pump is responsible for pushing fuel from the fuel tank to the fuel lines, and eventually the engine’s combustion chamber.
How can I check if my fuel pump is working?
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.
Where can I get a fuel pump gauge?
Get a fuel pressure gauge. Commonly available at most auto parts stores for $20-30, a pressure gauge is a good investment, useful on most makes and models of cars. If you don’t want to buy one, you can also often borrow one from machine shops or auto shops who have them to lend.
Where is the fuel pump located on a 1G?
The fuel pump part of MPI relay (inside the passenger side of the console below the radio) on a 1G has two inputs, one from the starter circuit and one from the ECU. If your Haynes manual says that the pump should run with the ignition in the RUN position rather than in the START position, it’s wrong.
Where is “my” fuel pump relay?
Most fuel-pump relay units are located under the dashboard near the steering column. In some cases, the unit is located in the area where the steering column is mounted or near the engine’s firewall.
Is the fuel pump suppose to run in the run position?
If your Haynes manual says that the pump should run with the ignition in the RUN position rather than in the START position, it’s wrong. A 2G has a relay for the MPI and one for the fuel pump. The fuel pump relay only has a single input from the ECU and no connection to the starter circuit.
Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.
Where is the weep hole on a mechanical fuel pump?
Most mechanical fuel pumps have a weep hole on the bottom side of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems. Usually found on classic cars between 30 and 60 years old.
How old is the fuel pump on a classic car?
When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems. Usually found on classic cars between 30 and 60 years old. The internal rubber diaphragm is capable of lasting a long time.
When did the Chevrolet Celebrity station wagon come out?
The Celebrity shares its roofline with the 1982-1988 Buick Century and is distinguished from other A-platform vehicles by its coved rear fascia. For 1984, Chevrolet introduced a five-door Celebrity station wagon; for the first time since 1977, a mid-size station wagon was available with a third-row seat.
Where is the fuel pump located on the Mitsubishi Challenger?
Remove the high pressure fuel hose at the body-side main pipe connection, unfasten the pump-side connection. Wrap each joint in a rag before loosening; some pressure may remain within the system. Remove the fuel pump retaining nuts and carefully remove the pump from the tank. The fuel pump may still contain liquid fuel.
Where is the fuel pump shut off switch located?
On Ford, Peugeot, VW, Citroen, Vauxhall, Subaru, Renault, Toyota and Mazda, inertia switch location is usually on one of the following two hidden places: Behind or below glove compartment, sometimes hidden under the carpet; On the driver side, between the footrest area and door, sometimes hidden under the carpet.
What to do if your fuel pump is not working?
Check out your vehicle’s service manual to find out where to check and the proper procedure for checking it. Test for source voltage, to determine whether or not the good charge that’s leaving the fuse is getting to the pump. If no power is making it to the fuel pump, then check the fuel pump relay circuit.
How does a sensor work on a fuel pump?
Fortunately, modern cars are riddled with sensors that can detect any number of problems as they happen. Among those sensors is a fuel pressure sensor placed intelligently near the fuel pump. If there is any irregularity detected, the sensor sends a signal to the ECU, which illuminates the Check Engine Light.
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.
