We recommend testing or replacing the following: here
Many other symptoms may occur that can drastically lead to an ECU failure such as: more
To test for fuel pump problems you will need a fuel pressure gauge. Connect the gauge to the fuel system after the pump and as close to the fuel rail as possible. Although the fuel pressure might indicating correctly at idle it does not mean that the pump can maintain full pressure at wide open throttle. If the fuel system is a return system make sure that the gauge is hooked up before the fuel pressure regulator. [links]
Our inboard and outboard fuel injector cleaning service, is performed by knowledgeable and experienced technicians. Included in our service is ultrasonic cleaning, before and after flow testing and the replacement of most O-rings and filter baskets. *
Safety First: When working on fuel systems always keep suitable fire extinguishing equipment on hand. If you are not sure of what you doing get a professional to do it for you. [links]
The boat or watercraft gets up on plane but cannot reach full operating rpm and fuel consumption increase. more
Beware: Fuel injection cleaners used at the wrong time can cause severe engine damage [links]
Since 2006, we have maintained a turnaround time of 24 -48 hours and our prices are more than fair for the service we provide. In the event we need more than 24 hrs we will contact and inform you.
Leaky injectors can also cause the car to flood -- that's when the engine is shut off with excess fuel trapped in the system. The fuel then vaporizes, settles and purges when the car is restarted, which can cause extensive damage [source: Allen]. [links]
Fuel injectors are a key part of modern automotive systems, as they're responsible for getting gasoline into the engine in a precise, orderly and carefully engineered pattern. In general, they're expected to last a pretty long time. Both Bosch and Delphi, two major manufacturers of automotive components, say their fuel injectors have a life expectancy of 1 billion cycles. Essentially, that means that the fuel injectors should last as long as the car does.
Still, faulty injectors can't be overlooked or ignored for long. Dirty or worn-out injectors can also cause preignition or detonation [source: Carley]. Detonation is a fairly common problem in which gas remaining at the end of the normal air/fuel burning cycle (which is set off by the spark plug) spontaneously combusts. Detonation is harmless in some cases, but the pressure has potential to break engine components and cause pitting and scuffing around the pistons. Preignition is when the air and fuel combust before the spark plug fires, causing severely increased engine temperature and damaged pistons. This problem is much more likely to pinpoint a leaky injector than detonation is, because it's a relatively rare occurrence in fuel-injected engines. [links]
Regularly changing your fuel filter (according to your vehicle manufacturer's recommendations) will help keep debris from circulating. You can also add fuel injector cleaner to your gas tank, which may help solve running issues such as sputtering. Doing this at regular intervals of 10,000 miles or so might provide more cleansing than your engine actually needs, but it won't harm the system [source: Allen]. Keep in mind, though, that while fuel injector cleaner can help restore your car's performance so that its power and mileage are closer to new, it can't improve your car beyond its original specs [source: Allen]. more
Faulty fuel injectors on late-model cars will make their presence known by causing a cylinder to misfire. This is because on newer fuel-injected systems, the injectors work in sequence, and when the engine misses a dose of fuel, it won't run smoothly and may suffer damage over time. It's less of a problem in older cars featuring simultaneous injection systems, because good fuel injectors can sometimes compensate for weaker injectors, allowing the engine to recover its sequence more quickly. [links]
Try cleaning your injectors before considering a replacement [source: Carley]. When replacement is the only option, take heed: At the very least, you'll need to replace only the faulty injectors [source: Carley]. They can cost several hundred dollars apiece, depending on your car, but you can ask your mechanic to look for rebuilt or remanufactured OEM (original equipment manufacturer, or factory quality) injectors to pare down the cost.
So, fuel injectors do not last forever. But, you can take steps in preserving their lifespan, for as long as possible. Also, fuel injectors are, a very important component of modern vehicles. Not only do they deliver fuel to a car’s engine, but they do so in a manner that is; efficient as possible.
Over time the nozzle of the injector can become dirty and partially blocked. When you shut off your engine the injector will, soak up the heat of the engine.
So, when looking for problems, always start by hooking up an (OBD) code reader. This will tell you if the Engine Control Unit (ECU) has logged any errors. If an engine misfires because of a bad injector; there will be an error code, that will point to the injector in question. more
If the fuel injectors are not operating properly, then other parts of the engine will be affected as well. Therefore, if this precision is thrown off by restrictions; electrical problems or fuel problems, it can cause driveability issues.
They probably won’t, or make much difference, to a car that is running properly. I usually do not recommend additives, but this is one area that does help. [links]
It can also be a good idea to run a fuel system cleaner through your engine; a couple of times a year. This will help to keep injectors, fuel pumps and fuel lines clean and clear of, carbon build ups. It will also, increase the service intervals of the injectors.
