Is there a problem with the number 2 injector?

Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu. Look at wiring diagrams again and trace the injectors back to the ecu, checking for voltage just like you did before. Most likely you have an open somewhere. found the problem, the wire from the #2 harness to like where the CAS looked a little brittle.

How are fuel injectors fired in a DSM ECU?

The DSM ECU uses sequential firing of the injectors most of the time, we have injector drivers for each injector. It’s not a batch fire setup except when cold starting and under acceleration enrichment. The DSM ECU uses sequential firing of the injectors most of the time, we have injector drivers for each injector.

Why is my injector pulse not working on my car?

Ans: Having a stuck or clogged injector is a very wide known problem that happens because of the accumulation of carbon build-ups that coming out from using a low-grade fuel, so regularly using a fuel system cleaner can help you in this mission.

Can a car injector be pulsed on a multimeter?

With the car running, it may be hard to see because multimeters are so slow, but you should get a pulsed battery voltage. It will probably just show up as a constant voltage on the multimeter however. If you don’t get it, the injector isn’t being pulsed. Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu.

What happens if the fuel injector is not working?

Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.

Which is the wire to the injector resistor pack?

The wire to the injector resistor pack is the power wire. Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu. Click to expand… The DSM ECU uses sequential firing of the injectors most of the time, we have injector drivers for each injector.

When to look for a clogged fuel injector?

When you notice any of these clogged fuel injector symptoms with any of your vehicles or other mechanical equipment using fuel injected engines, it’s definitely a good idea to look into some injector cleaning products. However, once again it pays to emphasize the value of prevention.

What should I do if my fuel injector is not working?

Hopefully, these tests have allowed you to find the issue with your fuel injectors; but, as mentioned before, it may not be an electrical problem that is causing the injector to malfunction. The next step if the injector resistance is normal would be to remove the injector and test the spray pattern it produces on an injector tester.

Which is the hot side of the fuel injector?

One side is hot/12v the other side is ground to fire the injector. The ground side is controled by the ecu. The best thing to do is get a manual/wire diagram at hondatech.info: Honda service manuals and stat unplugging stuff till you find out what happens.

What should the resistance of a fuel injector be?

They will range from 12 to 17 ohms. Low impedance injectors are found on high performance and larger injectors. They have much lower resistance, typically around 2-5 ohms. Step 5: Repeat with all injectors. They should all have a resistance within half of an ohm from each other.

What causes wear and tear on fuel injectors?

Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.

What are the signs of a failed fuel injector?

The reasons fuel injectors fail vary, but here are five of the most common problems with fuel injectors. An abrupt loss of engine power is a somewhat obvious sign of a fuel injector failure.

Why is my 2 cylinder engine not getting fuel?

All the injectors are ticking perfectly fine. I switched injectors to stock and have 8 set of these injectors and no matter which injector I use, the #2 cylinder isnt getting fuel. The engine studders and has terrible rough idle at like 550rpm.

Why do fuel injectors need to be changed so often?

If an engine isn’t running efficiently, this can load extra pressure on injectors. It’s also important, to regularly change the fuel filter, to ensure a proper fuel flow. Driving Habits. Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors.

The reasons fuel injectors fail vary, but here are five of the most common problems with fuel injectors. An abrupt loss of engine power is a somewhat obvious sign of a fuel injector failure.

What causes a fuel injector to leak over the engine?

So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.

Can a fuel injector last the life of the engine?

In general, fuel injectors are hard wearing and with a little care, can often last; the life of the engine. Like any other engine part, regular maintenance is the key, to keeping them going.

Can a clogged fuel injector be repaired quickly?

Clogged injectors can usually be repaired, if you catch the problem quickly. Sometimes a fuel injector is completely clogged, because of years of neglect or a lack of regular engine servicing. If this is the case then a refurbished replacement, may be the only option.
