Fault codes P0087 and P1011 may be showing

Fault codes P0087 and P1011 indicate low fuel rail and low lift pump pressure. These codes are persistent and indicate a fuel supply issue prior to the CP3. This could be due to a restriction somewhere in the fuel line, which is causing a drop in supply pressure/volume under load, which in turn starves the CP3 pump and causes low rail pressure.

To resolve this issue, you should first check the fuel lines for any damage or pinch points. You should also check the supply pressure under load to ensure that it is adequate. If the supply pressure is low, you may need to replace the fuel pump or consider installing a fuel pressure regulator.

Other potential solutions include:

• Reloading the program and ensuring that the batteries are fully charged.
• Checking the pressure relief valve on the rail.
• Checking the FCA on the CP3.
• Checking the return line to ensure it is not plugged.
• Applying dielectric grease to the electrical connector for the pressure relief valve.
• Checking the vent valves, as a problem with these could be causing the issue when the tank is full.

The fuel heater may be the problem

If you're experiencing issues with fuel pressure in your 2014 Ram 3500, the fuel heater may be the problem. This is especially true if you live in a cold climate, where temperatures can drop to 20°F (-7°C) or below. At these low temperatures, the fuel in your Ram 3500 can start to gel, causing a range of issues.

One symptom of a faulty fuel heater is difficulty starting your engine or a complete failure to start. This is often accompanied by a malfunction indicator lamp (MIL) illuminating on your dashboard, signalling a fuel-related diagnostic trouble code (DTC). You may also notice that the frame-mounted fuel filter heater is not functioning, which is due to a configuration issue with the body control module (BCM).

Another indicator of a faulty fuel heater is a check engine light. Using an OBD scan tool, you may find the P2609 and/or P0542 diagnostic trouble codes. These codes indicate an issue with the intake air heater system voltage or performance, specifically with the grid heater bolt. Over time, this bolt can deteriorate and fall into the intake runner, leading to severe engine damage.

In addition to the issues mentioned above, you may also experience other symptoms of a faulty fuel heater or fuel pump in general. These can include a loud whine or buzzing sound coming from the fuel tank area, engine sputtering or stalling, and surging from the engine.

If you suspect that your fuel heater is the cause of your fuel pressure issues, it is recommended to have your vehicle diagnosed by a qualified technician. They will be able to properly identify the root cause of the problem and perform any necessary repairs or replacements.

There could be a problem with the high-pressure fuel pump leaking

The fuel pressure for a 2014 Ram 3500 is not publicly available. However, fuel pump problems can cause issues with engine performance, such as sputtering or stalling, difficulty starting the engine, or surging.

Now, there could be a problem with the high-pressure fuel pump leaking. Fuel pump leaks can be a serious issue and have several negative consequences. Firstly, they can cause a fire in the engine compartment, which is a significant safety risk. Additionally, they can lead to increased fuel consumption as the engine may not be receiving the optimal amount of fuel. Furthermore, fuel pump leaks can result in insufficient fuel pressure, causing a loss of engine power.

Leaking fuel pumps are often caused by worn-out seals. Over time, the seals can degrade and fail to contain the fuel, resulting in leaks. This is a common issue with high-pressure fuel pumps and can lead to diesel or gasoline leaking onto the gearbox and floor. It is important to address this issue promptly to prevent potential safety hazards and engine damage.

To fix a leaking high-pressure fuel pump, you may need to replace the seals or, in some cases, the entire pump. Before attempting any repairs, it is crucial to consult a professional mechanic or a specialist in diesel pump repairs. They will have the necessary tools and expertise to diagnose the issue accurately and recommend the best course of action. In some cases, it may be possible to repair the leak by tightening connections or replacing individual seals or O-rings. However, if the leak is more severe, a complete pump replacement may be necessary.

When dealing with fuel pump leaks, it is essential to prioritize safety. Always wear appropriate protective gear, such as gloves and eye protection, when working on fuel system components. Additionally, ensure the work area is well-ventilated to prevent the buildup of flammable fumes. By taking the necessary precautions and seeking professional assistance, you can effectively address a leaking high-pressure fuel pump and ensure the safe and efficient operation of your vehicle's fuel system.

There could be a problem with the fuel injectors

Fuel injectors are an essential part of your car's engine, delivering fuel at the right time to ensure clean and efficient combustion. However, without regular maintenance, they can develop faults or become clogged. Here are some signs that there could be a problem with the fuel injectors in your 2014 Ram 3500:

• Check Engine Warning Light: The most common sign of a bad fuel injector is the check engine warning light, which appears on the dashboard. This light will come on as soon as an injector isn't doing what it should, such as adding too much or too little fuel.
• Misfiring or Vibrating Engine: If your car often misfires or there's a delay after you press the accelerator pedal, it could be due to a faulty fuel injector, likely a clog or blockage in the nozzle. If the injector can't deliver the right dose of fuel, the fuel-air mix in the combustion chamber will be off, leading to misfiring or a sudden drop in acceleration.
• Rough Idle: If your car's idle noise has changed and feels rougher, the fuel injectors may not be delivering fuel properly. This is usually caused by injector nozzles being clogged with particles, which interfere with the atomization and spray of the fuel.
• Engine Stalling: If your engine randomly stalls or cuts out, it could be due to a lack of fuel reaching the engine from the injectors. Stalling typically occurs when the nozzles are badly blocked or when there's a fuel leak where the injector connects with the fuel lines.
• Fuel Odor: If you can smell fuel strongly while driving and your car is exhibiting other symptoms, you might have a fuel leak. Leaks can occur where the injector meets the injector, as well as on the injector itself if it's old and hasn't been maintained.
• Poor Fuel Economy: A faulty fuel injector can lead to a significant drop in fuel economy. This is because the engine is calling for more fuel from the injector but not receiving it, resulting in lower fuel efficiency.
• Engine Surge During Acceleration: Inconsistent injector performance can cause an occasional surge since fuel might be sprayed properly one moment and too much or too little the next.
• Cold Weather Issues: If you live in a cold climate, your 2014 Ram 3500 may experience fuel gelling in cold ambient temperatures (20°F or -7°C) or below. This can lead to a hard or no-start condition and a malfunction indicator lamp (MIL) illumination.

If you suspect that your 2014 Ram 3500 is experiencing issues due to faulty fuel injectors, it's important to have them diagnosed and serviced by a professional mechanic to prevent further damage to your vehicle.
