How to diagnose common rail diesel fuel injection system?

Tip 4: Change Fuel Filters Regularly and Improve Filtration. HPCR injectors are carefully built to exacting standards and are tested multiple times before they even make it into a box to be sold at the counter. If the injector does not pass these rigorous tests, the injector will have to be torn down to start all over again.

What should I do if my Ford fuel injector fails?

Fuel Injector Inspection – You can take the injectors out of your Ford and inspect them for damage, dirt or rust. You can start by removing the fuel rails and detaching each injector from the rail. When you remove the injector, there will be fuel that spills out of the rail, so make sure you do not get it on you or the ground.

How many pins are on the harness and fuel injector?

The White (7 pin) connector wasn’t detailed on Josh’s diagram, as it seemed to just connected to standard engine connections. However, for some reason he’d relocated all but one of the pins to different parts of the connector. I found it much easier to remove the male pins on the other side of the harness to make the connectors match.

What kind of wire is a fuel injector?

For mine the middle orange/black wire was the sense wire, the black/blue wire was ground, and the dark purple/white wire was the reference voltage. Then it was just a matter of stripping the wires, removing the old connector from the harness and soldering the new connector in place.

Why are my fuel injectors not working properly?

Take away the fuel rail from the intake manifold, lifting the injectors with it. You will use a little pressure or a good amount of force here. The reason is that the injectors are joined to the rail, and the sprayer tips are a tight fit in the intake manifold.

How long does it take to replace fuel injector?

But, if you need to replace the old fuel injector with a new one, on a do it yourself basis, with intermediate skills, it will take you between 1 to 2 hours. This guide is for an Engine Fuel System vehicle. Also, you will need to have an intermediate Skill Level to carry out this routine.

How is an injector related to an electric field?

An injector is a coil, from an electrical point of view. A coil that has a voltage applied to it and then when you turn it off, it fights to sustain its electric field. It wants to retain that charge and as the field collapses, it generates a fairly large very fast pulse of the opposite polarity (a phenomena called “Back EMF”).
