Most common cause of unusually high fuel comsumption is a fuel leak. Other possiblities include leaking injectors, faulty O2 sensor, vacuum leak or incorrectly adujsted intake valve.

If you are getting gas to the fuel injection but not out of the return line what could be the problem?

Fuel pressure regulator.


Why would a fuel injection bike bog down?

Bad fuel, dirt in the fuel filter, dirty air filter.


What makes the injectors work Getting fuel up to the pressure valve. Getting fire to the plugs. Plugs are dry. Is there a fuse that could be stopping the injectors?

Chances are your fuel pump or pressure regulator is bad, or your injection system is not working. There is a fuse for the injection system but it varies in location in every vehicle, some under hood, some in fuse box. Find the schrader valve on your fuel rail and press a pen tip to the valve (just like the air valve in your tires, have a friend try to start the car, if a small squirt or two of gas comes out of this valve when cranking you may have a bad injection control module, if no gas squirts (not dribbles) out chances are your fuel pump is dead. Common causes for a bad injection system or the injectors not operating is the crank sensor a.k.a. crank position sensor / crank angle sensor, the fuel injection system will not recognize that the engine is turning and will not activate the fuel injector units. Good luck!!


How does a direct injection systems work?

Direct injection works somewhat similar to regular fuel injection, but at a MUCH higher PSI. say a non-direct injection car's fuel pressure is anywhere from 40-60SPI, a direct injection fuel pressure runs in the couple of thousands of PSI for gasoline and up to and more than 20,000 PSI for diesel direct injection.the other difference is instead of the injector spraying the fuel into the intake manifold runner (where it has to travel a short distance to the combustion chamber, some fuel doesn't stay as a fine mist, it will stick to the wall of the runner and bead up, like rain on a window) direct injection sprays, you guessed it, DIRECTLY into the combustion chamber. it gives a good boost to compression, which gives you more power and better efficiency


What does it mean when your gas pedal doesn't pump?

What are the difference between petrol engine and mpfi engine?

There is no difference. Petrol is just another name for gasoline. MPFI just means Multi-Point Fuel Injection. A petrol (gasoline) engine can be MPFI or it can have a carburetor. It can have many different ways to get gasoline (petrol) to the cylinders.


Is fuel injection for diesel engines more efficient?

diesel only comes in fuel injection, the fuel needs high pressure to ignite, and cannot only be sucked in like with a carburator on a petrol engine


What is cetane number for petrol?

There is no cetane number for petrol. Cetane is a measurement of Diesel fuel and Octane is a measure of Petrol. Each is a measure of the combustion ability. Cetane is a measure of the amount of time from injection of the fuel into the combustion chamber and the actual ignition of the fuel. Diesel's ignite the fuel through compression and not spark as in a petrol engine.

How do you time a vw rabbit injection?

If this is a petrol vehicle with K-Jetronic injection (you will see four separate braided fuel hoses, one from the fuel distributor to each injector), there is no timing involved in the injection. Each injector sprays a constant mist of fuel.


How does petrol fuel ignite in the engine?

The compressed petrol gas fuel is ignited by a spark plug thus causing the engines' power stroke.
