Why does my 2003 Dodge Ram shut off? Every owner of a 2003 Dodge Ram has asked themselves this question at some point, especially if they have a 5.9 liter Cummins engine in it.

The good news is that we can answer that question and help you solve the problem.

Let’s dive into the crux, Why Does My 2003 Dodge Ram Shut Off?

Why Does My 2003 Dodge Ram Shut Off?

Typically when an engine shuts off while under acceleration, it is caused by an instant reduction in fuel flow or an ignition system component that failed.

Among the leading candidates include fuel pump failure, fuel pump relay, crankshaft or cam position sensor failure.

Are 2020 Ram Trucks Reliable?

According to a RAM user:

The 2003 Ram is a very reliable vehicle. I have owned my 2003 Ram 1500 for almost three years now, and it has been nothing but trouble-free. I have had no problems at all with it. I know that there are some issues with the transmissions in 2003 Rams, but mine has not had any problems at all.

The only thing that I have done to mine is to replace the fuel pump, which was under warranty due to a recall. Other than that, it has been great!

The only other problem that I’ve had with my truck is the air conditioner stopped working about two months ago. It was making a loud noise and then stopped working altogether.

A friend of mine told me that he thought it was just the compressor so I took it into a shop to get looked at. The repair cost about $200, but once again it was something very simple and easy to fix.

Does My RAM Have eTorque?

Ram eTorque is a new powertrain technology designed by Chrysler. It’s a system that helps with off-the-line acceleration and drivability, but it doesn’t replace or improve the traditional engine. Instead, it works in tandem with the engine to provide more torque for a smoother driving experience.

As of right now, eTorque is only available on the Ram 1500 pickup. While the Ram 2500 and Ram 3500 provide more powerful options, due to their heavy-duty design, they do not currently have eTorque engines available.

How Does It Work?

Ram eTorque works by using an electric motor mounted behind the radiator and connected directly to the crankshaft via a drive belt. This allows it to rotate at any time without any outside input from you or your foot on the gas pedal — similar to how an automatic transmission operates.

When you step on the gas pedal, your foot pushes on a piston inside your transmission which causes oil pressure to build up inside of it causing it to move forward and engage gears inside of your transmission box (or torque converter). As this happens, power is transmitted through a shaft which spins your rear axle shafts.

Why Does My Dodge Ram Start But Won’t Stay Running?

Your Dodge Ram is a great truck. The engine is powerful, the transmission shifts smoothly and everything else works just fine. But every now and then, you might experience some problems with your vehicle. One of these problems could be that your Dodge Ram starts but won’t stay running.

The reason behind this problem is usually electrical in nature. If there is an issue with the electrical system of your vehicle, then it may not be able to provide enough power to the starter motor to turn over the engine. As a result, it will shut down after a few seconds or minutes of running.

Most common causes of starting but not staying running issues:

The battery may be dead or disconnected
The starter motor may be faulty
Fuel injectors may be clogged or dirty
Ignition coils or spark plugs may be faulty

How Can I Clear Codes On 2003 Dodge Ram?

Here are the steps to clear your engine codes:

1. Turn the ignition switch to the OFF position.

2. Wait at least 10 seconds and then turn the ignition switch to the ON position, but don’t start the engine.

3. Perform this step only if necessary while testing or troubleshooting vehicle systems using a scan tool or jumper cables: Disconnect the negative battery cable from the battery. Wait at least 30 seconds before going to Step 4. This allows all capacitors in the power and ground circuits to fully discharge.

4. Connect a scan tool or jumper cables between the positive (+) and negative (-) terminals of the battery for about 5 seconds, then remove them from their connection points.

The purpose of this test is to verify that both circuits are free of voltage when disconnected from their respective power sources (ignition switch in Step 3).

If either circuit is still charged with voltage, there may be an open circuit in that circuit which will prevent clearing codes on some Chrysler vehicles.

Why Does My Dodge Ram Stall?

The most common reasons a Ram 1500 engine stalling are the fuel system, the air intake system, or the ignition system.

Fuel System

The fuel system can cause stalling when it gets dirty or clogged with particles and dirt. Injectors may leak, causing poor fuel delivery and stalling. A clogged fuel filter can also cause a Ram 1500 to stall while driving.

Air Intake System

The air intake system on your Dodge Ram 1500 filters air that enters the engine and ensures that only clean air passes through to be burned with fuel in order to produce power. The engine can stall if there is a problem with this system, such as a dirty air filter or clogged mass airflow sensor.

Ignition System

The ignition system is responsible for creating an electrical spark in order to ignite the fuel being burned by the cylinders in your Dodge Ram 1500’s engine. If this system fails, there will be no spark and your engine may stall while driving or idling at stoplights or stop signs.

Why Does My 2004 Dodge Ram 1500 Shut Off While Idling?

This is a fairly common problem with Dodge Ram trucks, especially the ones with the 5.7L Hemi engine. The issue usually happens during warm weather, and most often when you are sitting at an intersection or stoplight.

The engine will shut off for no reason, and sometimes the vehicle will not start back up again until it has cooled down to normal operating temperature.

If your truck begins to exhibit this behaviour, there are several things you can do to fix it:

Check for vacuum leaks – If your truck has a leaky intake manifold gasket or cracked manifold, this could cause your truck to stall while idling. This is because there is no vacuum signal for the fuel injectors when you stop accelerating and coast in neutral or park mode.

Check for a faulty fuel pressure regulator (FPR) – If your FPR isn’t working properly, it could cause this issue as well. When this happens, fuel pressure drops below 12 psi and shuts off fuel delivery to cylinders 2-6 (the ones that fire when you accelerate).

You’ll know if this is happening because your check engine light will come on when you start having these problems (this only applies to ’04-’07 Rams). Also, make sure that all of your electrical connectors are clean.
