Hey guys! Let's dive into the world of the 1987 Honda Accord LXi and tackle a pretty common issue: the fuel pump. Whether you're dealing with a sputtering engine or a complete no-start situation, understanding your fuel pump is crucial. This guide will walk you through everything you need to know about the fuel pump in your classic Accord, from identifying the symptoms of a failing pump to understanding the replacement process.

Understanding the Fuel Pump

Fuel pumps are a vital component in your 1987 Honda Accord LXi's engine. The fuel pump's primary job is to supply fuel from the gas tank to the engine at the correct pressure. Without a functioning fuel pump, your engine won't get the fuel it needs to run, leading to performance issues or a complete breakdown. In the 1987 Accord LXi, the fuel pump is typically located inside the fuel tank. It's an electric pump, meaning it relies on electricity from the car's electrical system to operate. Over time, fuel pumps can wear out due to age, contaminants in the fuel, or simply the stress of constant use. Recognizing the signs of a failing fuel pump early can save you from getting stranded and potentially prevent damage to other parts of your fuel system.

Symptoms of a Failing Fuel Pump

Okay, so how do you know if your fuel pump is on its way out? Here are some common signs to watch out for in your 1987 Honda Accord LXi:

• Difficulty Starting: This is one of the most common symptoms. You might find that your car takes longer to start than usual, or it might not start at all. This happens because the fuel pump isn't providing enough fuel to the engine quickly enough.
• Sputtering or Stalling: If your engine sputters or stalls, especially when you're accelerating or going uphill, it could be a sign that the fuel pump is struggling to deliver a consistent fuel supply.
• Loss of Power: A failing fuel pump can cause a noticeable loss of power, particularly at higher speeds. You might feel like your car is struggling to keep up, or that it's not accelerating as quickly as it used to.
• Rough Idling: If your car idles roughly, or if the RPMs fluctuate erratically, it could be due to an inconsistent fuel supply from a weakening pump.
• Poor Fuel Economy: A failing fuel pump can sometimes lead to poor fuel economy. This is because the engine isn't running as efficiently as it should, and it's using more fuel to compensate.
• Unusual Noises: Sometimes, a failing fuel pump will make unusual noises, such as whining or buzzing sounds, coming from the fuel tank area. These noises can be intermittent at first, but they'll usually become more consistent as the pump deteriorates.

If you notice any of these symptoms, it's a good idea to have your fuel pump checked out by a mechanic. Ignoring these signs can lead to further damage and a more expensive repair bill down the road.

Inspecting the Fuel Pump

Before you jump to replacing the fuel pump, it's a good idea to do some basic troubleshooting to make sure that the pump is actually the problem. Here are a few things you can check:

• Fuel Pump Relay: The fuel pump relay is an electrical switch that controls power to the fuel pump. If the relay is faulty, it can prevent the fuel pump from working. You can usually find the fuel pump relay in the fuse box, which is typically located under the dashboard or in the engine compartment. Check your owner's manual for the exact location of the relay. To test the relay, you can try swapping it with another relay that you know is working. If the fuel pump starts working after you swap the relays, then the relay was the problem.
• Fuel Pump Fuse: The fuel pump is protected by a fuse, which is designed to blow if there's an electrical overload. If the fuse is blown, the fuel pump won't receive power. Check the fuse box for the fuel pump fuse and inspect it to see if it's blown. If it is, replace it with a new fuse of the same amperage.
• Wiring and Connections: Inspect the wiring and connections to the fuel pump to make sure that they're in good condition and that there are no loose or corroded connections. Use a multimeter to check for voltage at the fuel pump connector when the ignition is turned on. If you're not getting voltage, then there's a problem with the wiring or the fuel pump relay.

If you've checked these things and the fuel pump still isn't working, then it's likely that the fuel pump itself is the problem.

Replacing the Fuel Pump

Alright, so you've determined that your fuel pump needs to be replaced. Here’s a step-by-step guide to help you through the process. Keep in mind that this is a general guide, and the specific steps may vary slightly depending on your exact model and trim level. Always consult your service manual for detailed instructions and safety precautions.

Tools You'll Need

Before you get started, gather the necessary tools and equipment:

• New fuel pump (make sure it's the correct one for your 1987 Honda Accord LXi)
• Fuel tank sending unit gasket/seal (it’s a good idea to replace this when you replace the pump)
• Socket set
• Wrench set
• Screwdrivers ( Phillips and flathead)
• Fuel line disconnect tool
• Hammer
• Punch or drift pin
• Multimeter
• Safety glasses
• Gloves
• Jack and jack stands
• Wheel chocks
• Fire extinguisher (just in case)
• Drain pan

Step-by-Step Replacement Guide

1. Safety First: Disconnect the negative battery cable to prevent electrical sparks. Use wheel chocks to secure the rear wheels and set the parking brake. Work in a well-ventilated area to avoid inhaling fuel vapors, and keep a fire extinguisher nearby.
2. Depressurize the Fuel System: Locate the fuel pump relay and remove it to prevent the fuel pump from sending fuel while you're working. Start the engine and let it run until it stalls. This will relieve the pressure in the fuel lines. Then, try to start the engine again a couple of times to make sure all the pressure is relieved.
3. Access the Fuel Tank: Depending on your Accord's configuration, you may need to raise the rear of the car using a jack and jack stands to access the fuel tank. Make sure the car is securely supported before proceeding.
4. Drain the Fuel Tank (If Necessary): If the fuel tank is full or nearly full, it's best to drain it before removing the fuel pump. Use a siphon or a fuel transfer pump to remove the fuel into a suitable container. Dispose of the fuel properly.
5. Disconnect Fuel Lines and Electrical Connectors: Locate the fuel lines and electrical connectors attached to the fuel pump assembly. Use the fuel line disconnect tool to carefully disconnect the fuel lines. Disconnect the electrical connectors as well. Be prepared for some fuel spillage, so have a rag handy to clean up any spills.
6. Remove the Fuel Pump Assembly: The fuel pump assembly is usually held in place by a retaining ring or screws. Use a hammer and punch or drift pin to gently tap the retaining ring counterclockwise to loosen it. If it's held in by screws, simply remove them. Carefully lift the fuel pump assembly out of the fuel tank.
7. Remove the Old Fuel Pump: Once the fuel pump assembly is out, you can remove the old fuel pump from the assembly. Depending on the design, it may be held in place by clips, screws, or a retaining bracket. Take note of how the old pump is oriented so you can install the new one correctly.
8. Install the New Fuel Pump: Install the new fuel pump into the fuel pump assembly, making sure it's oriented correctly and securely fastened. Replace any rubber seals or O-rings that came with the new pump.
9. Install the Fuel Pump Assembly: Carefully lower the fuel pump assembly back into the fuel tank, making sure the fuel lines and electrical connectors are aligned correctly. Secure the retaining ring or screws.
10. Reconnect Fuel Lines and Electrical Connectors: Reconnect the fuel lines and electrical connectors to the fuel pump assembly. Make sure the connections are secure and that there are no leaks.
11. Reinstall the Fuel Tank (If Removed): If you removed the fuel tank to access the fuel pump, reinstall it now. Make sure all the mounting bolts are tightened securely.
12. Lower the Car: If you raised the car to access the fuel tank, carefully lower it back to the ground.
13. Reconnect the Battery: Reconnect the negative battery cable.
14. Test the Fuel Pump: Reinstall the fuel pump relay. Turn the ignition key to the
