When is a fuel injector considered to be faulty?
Fuel injectors are deemed to be faulty if they do not operate as designed. Fuel injectors are considered to be clean if and when fuel delivery, atomization and distribution are within 1% of the design specification of that fuel injector. The injector cannot be recovered. We do not charge for the time spent on bad fuel injectors.
What causes a fuel injector to get clogged?
What causes clogging in fuel injectors or/ and their accompanying filter baskets is the presence of carbon, old fuel, and residue. You consider a fuel injector clogged when the quantity of gunk or debris within has built up so much that it hinders the free flow of fuel.
Can a fuel injector be cleaned outside the engine?
Although there is some quality fuel injection cleaners that might help to keep your fuel injectors in good shape the only true and tested way to clean fuel injectors properly are and have always been to do it outside the engine and with the proper cleaning equipment. This process is inexpensive and has saved our customers thousands of dollars.
What happens if you put too much gasoline in the injector?
Either way, you need to find the cause of the gasoline odor and fix it right away before it becomes a big safety hazard. If the fuel injector is spraying too much fuel into the engine cylinder, this will create a surge in the engine causing your acceleration to be much slower.

Fuel odor 3. Check Engine Light comes on Fuel injectors are an engine management component that is found on the vast majority of road going vehicles.
Are there any misconceptions about fuel injection?
Many mechanics and most riders really don’t have a good idea on how EFI works and how the primary components interact. Misconceptions about EFI abound and the amount of bad information being passed around is high. By the time you have finished this article, you should be thoroughly confused or have a new understanding and appreciation for EFI.

When to replace ignition coil on Johnson Evinrude?
Ignition Coil for Johnson Evinrude Outboard Outboard ignition coils, sometimes called coil packs, supply the high voltage required to fire spark plugs. When low spark is detected on a plug, it might be time to replace a coil.
What to do if your ignition coil is not working?
Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor. The ignition module uses the information to time spark generation. Test these components if the energized coil fails to function.
Why are my ore multiple cylinders not firing?
They acts the same as a bad coil, a broken spark plug wire or a bad spark plug. one ore multiple cylinders are not firing. Old fuel, carbon and residue inside the fuel cause fuel injectors and/or their filter baskets to become clogged.
Why is my fuel injector # 2 cylinder not getting fuel?
No Pulse I hooked a stethoscope to the injector #2 and it has no pulse. 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.
When is a fuel injector not a batch fire?
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. It’s not a batch fire setup except when cold starting and under acceleration enrichment. Click to expand… Ah yes, you’re right.
Can a bad coil on a cop ignition be repaired?
Even if you find a bad coil, simply replacing it is not the whole repair, because like so many other parts of a vehicle, COP ignition coils don’t really die, they’re murdered. We’ll discuss how and why later; first let’s focus on finding the misfire. Ignition misfire diagnosis can be relatively quick and simple if you have the right tools.
