When you are looking to buy a diesel pump to replace your old one it is important to match up the part numbers to be sure it’s the correct one for your car. Get it right the first time. You do not want to purchase the wrong one and then go though the process of finding the correct one all over again.
At Your Car Spares Ltd – What we test and look for!!!!
Every part is different so we need to look out for different things for different parts. Testing a diesel fuel injector pump isn’t as easy to test as other parts and the best way to test a diesel pump is to remove it from the car for a closer inspection. The reason why it is hard to test is because the diesel fuel injection system has evolved over the years and it has become so much more sophisticated that diagnosing a problem has become a lot harder and often the best way to do it is to take it to a professional. If the car doesn’t start it can be for numerous reasons but in order to rule out it is the diesel injector pump we need to get close to it to listen for any noises. If an injector pump ‘clicks’ when you turn the key in the ignition then that means there is power in the pump , but if it ‘clicks’ and it still doesn’t start then you need to check the fuel lines to ensure fuel is being passed through and there’s no obstructions in the lines. Another test is to use clear fuel lines and to see if fuel is being sent to the fuel injector pump and then to see if fuel is being sent to the injectors.
Where to find the Part Number
The most common manufacturer of diesel fuel injector pumps is Bosch. Below we will show you two different types of Bosch injector pumps and where to find the part number them. Diesel fuel injector pumps will have a manufacturer part number and an original equipment manufacturer (OEM) part number which is from the car manufacturer.
How a Diesel Fuel Injector Pump works?
The diesel fuel injector pump , often referred to as a high pressure fuel pump or an engine fuel pump , is a vital part of the fuel system and the running of a car. The injector pump is responsible for bringing in fuel from the fuel tank, through the fuel system and then distributing it into the injectors at the right time to ensure the engine runs smoothly and in a cycle. The amount of fuel used by the injector pump is dependent on how much pressure you put on the throttle pedal , the more you push on the pedal the more fuel the injector pump needs to give out. The injector pump can also store fuel and send it out at an incredibly high pressure which is measured in psi (pound per square inch). During the process the fuel will be cleaned out as it travels from the fuel tank to the injector pump to ensure there are no particles in the fuel that will damage the engine. The fuel system starts with fuel being moved from the fuel tank by a fuel sender unit through the fuel lines then through the fuel filter where the fuel is cleaned. The fuel filter will hold any particles that try to pass through as well as water. Some systems do vary and as such there may be additional parts in the process. Some systems will use a pressure sensor on a fuel rail to determines the pressure in the fuel rail and then relays this information to an ECU. The ECU controls the injector pump and if the pressure in the fuel rail is too low it will tell the injection pump to release more fuel into the rail.
