How do you know when diesel injectors are bad?

Here are the 5 most common symptoms of faulty diesel fuel injectors.

1. Trouble starting the vehicle or uneven idling. The engine cranks but doesn’t start unless you crank it for a long time.
2. Misfire.
3. Smell of fuel.
4. Dirty emissions.
5. Increased fuel consumption and poor miles per gallon.

How do you diagnose a bad injector on a 6.0 Powerstroke?

An injector buzz test will usually tell on a sticking injector. You have to do the test with the motor cold. Also a cylinder contribution test on a cold motor will tell what’s working and what’s not. The autoenginuity can perform a buzz test on the 6.0 but not a contribution test, yet.

Is it bad to run a diesel with a bad injector?

Left too long, a faulty fuel injector can cause serious engine damage that requires major repair. Avoid the cost and hassle by using Rislone Gasoline Fuel System Treatment or Diesel Fuel System Treatment every 3,000 to 5,000 miles, depending on the type of driving you do.

What sends signal to injectors?

The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.

Will bad injector throw a code?

One of the obvious symptoms of a clogged fuel injector is the lighting up of the “Check Engine” light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes. While the engine is running, monitor the engine misfire screen on your scanner.

How can you tell if a fuel injector is bad?

Check the exhaust smoke from your vehicle. White smoke is normal when starting your vehicle, but white smoke when driving indicates that there is a loose injector. Black smoke emission can also be normal when accelerating the vehicle, but if you notice black smoke at other times, this indicates a bad fuel injector.

Can a Ford PowerStroke Buzz test an injector?

Yes, you can run an injector buzz test using Ford’s IDS or most generic scan tools. However, that only tests the electrical side of the business . If a code is flagged to specific cylinder (s) for low/high circuits, that only narrows it down to either the FICM, the injector harness, or the injector itself.

When to replace the injectors on a PowerStroke?

As is the case with other fuel injection systems, PowerStroke injectors undergo normal wear and tear and must be replaced periodically. Learning to recognize the symptoms of a bad injector will allow you to determine when it is time to replace the injectors.

How does the PowerStroke fuel injection system work?

The PowerStroke fuel injection system is designed for diesel vehicles and uses a mix of hydraulic injectors with electric injectors. Given this combination of systems, the PowerStroke injection system faces the challenge of keeping air out of the vehicle´s oil (as opposed to non-diesel vehicles, where air must be kept out of the fuel).
