How to Troubleshoot a Failing Fuel Pump

If your vehicle uses a fuel injection system, a fuel pump (FP) is needed to send gasoline from the gas tank to the injectors. It also needs to apply the right amount of pressure in order for your engine to operate efficiently. An insufficient amount of pressure results in too little fuel in the combustion chamber. That leads to a lean mix, which can cause misfires and stalls. Too much pressure, on the other hand, will waste gasoline, generate pollution, and cause your engine to run rough.

The FP is responsible for two jobs. First, as mentioned, it must deliver fuel under pressure, and it must do so between a certain range. Second, it must deliver a sufficient volume of gasoline. Like all components, the fuel pump can eventually fail to work properly. This article will provide a few suggestions for troubleshooting and fixing the problem.

When Your Engine Refuses To Start

When the FP dies, it can prevent your engine from starting (even if it cranks). The problem is, there are other factors that can produce the same outcome, including issues in the ignition system and the engine. To narrow down the culprit, use a spark plug tester (you can buy one at most auto supply stores) to test for spark.

If the ignition system is fine, inspect the timing belt; you may need to remove a cover in order to see it. If the belt appears fine, crank the engine to make sure it turns. If it does, that usually means there's sufficient compression.

If you can rule out your vehicle's ignition system and the level of compression, the only other explanation is insufficient fuel. At this point, the goal is to figure out whether the pump is the problem.

A lack of sufficient fuel can be traced to the pump, the fuel filter (which can be clogged), or a pressure-related issue. Pressure can be affected by a blockage somewhere in the fuel line or too little voltage being received by the pump.

Checking The Pump

Have a friend turn the key in the ignition to crank your engine. While he or she is doing so, listen for the fuel pump being engaged (you'll hear a dampened buzzing sound). Normally, when the key is turned, the powertrain control module (PCM) engages the FP for a few seconds to build pressure. If your engine starts, the FP would continue to operate. In the event your engine refuses to start, the PCM would turn the FP off.

If you are unable to hear the pump working for the first few seconds after cranking your engine, the component has likely died; it will need to be replaced. But suppose you can hear a buzzing sound as the part is engaged. That suggests the problem involves a lack of pressure.

How Much Pressure And Volume Is Being Produced?

Checking the level of pressure generated by your car's fuel pump may require several different tests. These include static, residual, running, and dead head pressure tests. Each procedure requires a special gauge, which is used to assess the amount of pressure in various circumstances. For example, a running fuel pressure test is done while the engine is idling. A residual pressure test is performed several minutes after the engine has been turned off.

If the fuel pump is producing a sufficient amount of pressure, it is still possible that it is sending an insufficient volume of gas. For that reason, you may need to do a volume test. This test is performed using a fuel flow gauge that is connected to the fuel line.

If you determine that the FP has indeed failed, you'll need to install a replacement. Doing so can be expensive. The pump may cost nearly $250 and the labor can cost another $150 or more. Avoid cutting corners with this part. Use an OEM-certified replacement to ensure it lasts for years.

Fuel Injection $81.25 Fuel injection is a system for mixing fuel with air in an internal combustion engine. It has become the primary fuel delivery system used in gasoline automotive engines, having almost completely replaced carburetors in the late 1980s. A fuel injection system is designed and calibrated specifically for the type(s) of fuel it will handle. Most fuel injection systems are for gasoline or diesel applications. With the advent of electronic fuel injection (EFI), the diesel and gasoline hardware has become similar. EFIs programmable firmware has permitted common hardware to be used with different fuels. Carburetors were the predominant method used to meter fuel on gasoline engines before the widespread use of fuel injection. A variety of injection systems have existed since the earliest usage of the internal combustion engine. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure, while a carburetor relies on low pressure created by intake air rushing through it to add the fuel to the airstream.
