Modern internal combustion engines are fitted with fuel injectors. They`re used to control and atomise the fuel that goes into the Mazda 3`s engine.
To remove carbon and other types of buildup from your vehicle`s fuel injectors, you must use a high-quality injector cleaner. There are hundreds of cleaners on the market today. While there is a difference in fuel system cleaners, any cleaner that you use at 100% strength is apt to do a good job.
A fuel injector cleaning service flushes out all the build-up and cleans the injector. By removing all the build-up of carbon deposits and flushing them out of the fuel system, your car engine will run smoother and become more fuel efficient.
For the first dose, simply install when you have a full tank of gas. It`s that simple. From there, many experts will probably tell you that you should add a fuel injector cleaner to your gasoline every time you fill your tank up.
The main focus of Mazda`s Skyactiv Technology is the interal combustion engine, direct injection engine.
A new-generation highly-efficient direct-injection gasoline engine that achieves the world`s highest gasoline engine compression ratio of 14.0:1.
Reiterating what he said earlier Richardson noted, “If you`re going to use gasoline you`re going to have these (carbon) problems,” which is why fuel-system cleaners can be beneficial. Fortunately for drivers they`re affordable and totally safe.
A clean fuel system makes your car run better. When you hit the gas, you`ll really be able to accelerate. You won`t experience any engine hesitation or sputtering as a result of clogged fuel injectors. And when you`re trying to merge into traffic, you`ll know your car will be able to keep pace.
You can also clean the injectors yourself with a few simple tools. First, remove the fuel injectors from the engine and disassemble them. Then, soak the injectors in a cleaning solution for a few hours. After that, use compressed air to blow out any remaining deposits.
There is one injector per cylinder in an engine.
Most cars and light trucks with internal combustion engines are equipped with one fuel injector per cylinder.
Now, all cars sold in the United States have fuel injection systems. In this article, we`ll learn how the fuel gets into the cylinder of the engine, and what terms like “multi-port fuel injection” and “throttle body fuel injection” mean.

I have a 1981 e-350 with dual fuel tanks the p.o. added a third tank and 3 electric fuel pumps along with sepparate gauges and swi
ANSWER : The switch you are referring to is vended with the required electrical and fuel schematic (I just looked in the box) that answers your installation question. If you want an advance view, here is a link as well. Yes, you need a return line and just refer to the aforementioned link. If you are retrofitting back to OEM, I strongly encourage you to buy the original Factory Service Manual (FSM). There are lots of details attending this system and obviously it is difficult to recount it all here. The FSM will make your life much easier and you can then make sure your installation is perfect. Alternatively, YourMechanic can dispatch a certified mechanic and perform the whole retrofit and check out if you desire. Just request and schedule a generic service such as fuel pump service and the mechanic will come to your location and estimate the parts and labor required. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

1996 F150 4.9 5 speed. Frt. Fuel pump quit working. Put fuel in rear tank and it sucked the fuel to the frt tank.
ANSWER : The two tanks are designed to work together and so BOTH pumps must be functioning and, as well, the related fuel system supply code, the Code P0232 that has set has to be resolved. P0232 means that the fuel pump relay is stuck on, keeping power supplied to the fuel pump even after the ignition has been turned off although another possibility is the fuel pump secondary power circuit has a short to battery voltage. The factory service manual (FSM) specifies a very lengthy diagnostic (because you have separate tanks). If you do not have the FSM, your best bet is to request a fuel pump diagnostic – dual tanks and let a certified mechanic get to the bottom of this. With regard to the other code, P0704, that code will set if the clutch switch is defective, there is worn clutch pedal lever or clutch lever bushing, shorted or open wiring and/or connectors in the clutch switch circuit, a blown fuse or burnt fusible link and/or, rarely, a faulty PCM or programming error. If you request the pump diagnostic the responding certified mechanic will get this taken care of for you.

Diesel put into gas tank
ANSWER : Unfortunately our mobile technicians are not equipped to perform this kind of service. In all likelihood, the fuel tank will have to be removed from beneath the vehicle to be properly drained and cleaned. The the fuel lines all the way to the fuel injectors will have to be flushed. The injectors may be cleaned at the same time, or may require removal as well in order to be properly cleaned. The fuel filter should be replaced as well. Its is an expensive and time consuming thing. I am not sure if the national chain-type repair facilities will be able to handle this type of repair. The only real way to find out would be to contact them. If not, then a local independent or dealership repair facility should be able to correct this for you.

I have a truck that won’t run and is not getting gas to the engine. Fuel pump is running, have a new filter and new fuel pressure
ANSWER : Hi There,
It sounds like you may have a clogged fuel injector or potentially a faulty injector that is fried internally. I would suggest testing them if you have access to a multi meter. Disconnect the injector from the electrical connector and set your multi meter to Ohms mode and measure the resistance of the injector. After testing all injectors, compare the resistance. They should be the same or very close. If they are not, they will likely need to be replaced.

Can 1 man replace a fuel pump and sending unit, clean out sludge and particles from fuel tank in about 1 hour? Think I was scammed
ANSWER : To drop the fuel tank on your model, and immediately re-install the tank (without any cleaning or service) would require about 2 to 3 hours in total for an experienced professional if a lift is available. The fuel pump itself can be installed without removing the tank but to do that you must have access to the inside of the car because the pump is removed through an access panel under the rear seat. Also, you can’t drop the tank without access to the inside of the car because to drop the tank the wiring harness has to be disconnected and that connection is only accessible from inside the car. So, if the car was locked, obviously no work was performed on the vehicle. YourMechanic does offer these services and you can start by requesting fuel pump replacement. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Ran out of gas and put in diesel by mistake. Dealership drained the gas and changed the fuel injectors. Then they cleaned the system and now it has lost compression.
ANSWER : Hi there. Take a compression gauge and put it into the spark plug holes and remove all the other spark plugs. Then disable the ignition power to the coils. Then crank the engine over with the throttle open all the way. Check to see what the compression is on the engine. If there is good compression, then the engine did not loose compression. The fuel pump may have burned up from having diesel in the fuel and left in there too long. If there is no compression on all of the cylinders, then either the head gasket is completely burned up on both banks or all of the exhaust valves are burned. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your engine not starting after cleaning out the fuel system from accidentally putting in diesel in the fuel tank.

Will not start. Acts as if it’s not getting gas.
ANSWER : As you may know, the motor requires a very precise mixture of fuel and air in order for it to run properly. When the fuel injectors are not spraying an even, uniform pattern of fuel, this causes an imbalance in this air.fuel mixture resulting in the motor often times starving for fuel or in some cases being flooded with too much fuel. In your case, it sounds like the motor is starving for fuel as indicated by the motor running fine once fuel was sprayed directly into the intake. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
