How To Be Proactive With Diesel Injector Replacements

Throughout my years as a professional repair technician, I have found that fuel injector replacements always come in phases. Maybe because of some bad loads of fuel, potential car vandalism, or just a lack of proper care and maintenance?

Whatever the reason, the technology driving the common rail system attached to the after-treatment system usually requires the use of fuel injector programming. This fine tuning helps keep the engine performing at its peak capabilities and emissions down to the strict standards required.

These fuel injector programming codes can actually be very long, which can ultimately produce some errors when trying to type them in. Also, if there happens to be a programming failure after they are installed and the engine is assembled, then engine disassembly will be needed again. This leads to additional down time, and added frustration for the technician and customer alike.

Thanks to advances in technology over the years, including adding scanners for QR style codes, many of the common mistakes have been reduced.

One of the best practices I’ve been following is to preprogram the new fuel injectors before installing them, which ensures that there are no programming issues. An important point to note: Make sure to label the fuel injector with the corresponding cylinder number during the programming process.
