What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Drive On Diesel, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Drive On Diesel offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

Fuel injectors are critical components in modern engines, responsible for delivering the precise amount of fuel to the combustion chamber. When they malfunction, it can lead to a variety of engine performance issues. Diagnosing a fuel injector problem involves several steps to identify and address the issue effectively. Here’s a comprehensive guide on how to diagnose fuel injector problems.

Steps to Diagnose a Fuel Injector Problem

  • Check Engine Light

    • One of the first signs of a fuel injector problem is the illumination of the check engine light. Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs) from the engine control unit (ECU). Codes related to the fuel system, such as P0171 (System Too Lean) or P0300 (Random/Multiple Cylinder Misfire), can indicate injector issues.

  • Visual Inspection

    • Start with a visual inspection of the fuel injectors and surrounding components. Look for signs of fuel leaks, such as wetness around the injectors, fuel odor, or visible cracks in the injector body. Ensure all electrical connectors are securely attached and free of corrosion.

  • Listen for Unusual Noises

    • Use a mechanic's stethoscope to listen to each injector while the engine is running. A healthy injector should produce a consistent clicking sound. If you hear irregular or no clicking, it might indicate a faulty injector.

  • Check Engine Performance

    • Pay attention to engine performance symptoms such as rough idling, misfires, hesitation during acceleration, or a noticeable drop in power. These symptoms can be caused by faulty injectors that are not delivering fuel properly.

  • Perform a Fuel Pressure Test

    • Use a fuel pressure gauge to measure the fuel pressure in the fuel rail. Compare the readings to the manufacturer's specifications. Low or inconsistent pressure can indicate a problem with the fuel injectors or the fuel pump.

  • Use a Noid Light

    • A noid light test can help determine if the injectors are receiving the correct electrical signal from the ECU. Disconnect the injector connector and plug in the noid light. Crank the engine and observe the light. A flashing light indicates that the injector is receiving the signal correctly; no light suggests an electrical issue.

  • Conduct a Balance Test

    • A fuel injector balance test can help identify injectors that are not delivering the same amount of fuel. Using a scan tool, disable one injector at a time while the engine is running. Observe the RPM drop for each injector. A smaller drop indicates a problem with that injector.

  • Perform a Cylinder Drop Test

    • This test helps determine if an injector is causing a misfire. While the engine is idling, disconnect one injector at a time and listen for a change in engine RPM. If there is no change in RPM when an injector is disconnected, that injector may be faulty.

  • Inspect Spark Plugs

    • Remove and inspect the spark plugs for signs of fouling or discoloration. Wet or blackened plugs can indicate that an injector is leaking fuel or not atomizing fuel properly.

Maintaining your vehicle's fuel injectors is crucial for ensuring optimal engine performance and fuel efficiency. Regular inspections and timely replacements can prevent these symptoms and keep your vehicle running smoothly.

In conclusion, diagnosing a fuel injector problem involves checking the check engine light for trouble codes, performing visual inspections, listening for unusual noises, evaluating engine performance, conducting fuel pressure tests, using a noid light, performing balance and cylinder drop tests, and inspecting spark plugs. By following these steps, you can accurately identify and address fuel injector issues, ensuring your vehicle continues to perform at its best. Regular maintenance and early diagnosis are key to preventing more serious engine problems and maintaining overall vehicle health.
