Testing fuel injectors is a routine maintenance item for diesel trucks, but it’s not a service that just any mechanic can do. When people in Las Vegas ask “who offers diesel injector testing near me,” there’s a reason why this is often recommended. We have both the equipment and the expertise to properly check whether diesel fuel injectors are functioning to OEM standards.
Diesel Fuel Injector Testing for Many Diesel Engines
We’re able to test both common rail and manual diesel injectors, which allows us to provide diesel fuel injector testing for a wide range of engines. We regularly check injectors on Ford, Chevy, GMC, Dodge, Cummins, Detroit Diesel, Caterpillar, John Deer, Sprinter and Isuzu engines. Just some of the more common engines that are regularly in our shop for this service include:
- Ford 6.0L, 6.4L, 6.7L and 7.3L engines
- Chevy/GMC 6.6L engine
- Dodge/Cummins 5.9L, 6.7L and 3.0L engines
- Cummins ISB, ISC, ISL, QSL and ISX engines
- Cat 2126E, 3406C, 3408, 3412, C-7, C-9, C-10, C-12, C-13 and C-15 engines
- Detroit Diesel common rail engines
- John Deere common rail engines
- Bosch engines
There are many other engines we can test in addition to these. Whether you have an older engine with manual injectors or a more recent one with common rail injectors, our experienced team will know how to check them.
State-of-the-Art Equipment for Common Rail Injectors
Common rail injectors were developed in order to meet stricter emissions standards, and they’re computer-tuned. Properly checking these injectors requires a computerized test bench that’s capable of checking a specific engine’s injectors, and we have state-of-the-art benches for the engines we service.
When you bring a common rail engine in for fuel injector testing, we’ll connect each injector to the test bench. The injectors are connected individually, and then the bench puts them through a variety of checks:
- Injector start behavioral test
- Control valve leak test
- Full-load quality test
- High-pressure nozzle test
- Idle speed tuning
Without the necessary equipment, these tests can’t be conducted on common rail injectors.
Experienced Technicians for Manual Injectors
Checking manual injectors is a much more hands-on approach, and it’s important that the tests be conducted by an experienced technician who knows what to look for. Our ASE-certified technicians are highly trained and have checked many manual injectors, and they know how to do this test.
When you bring manual injectors in for fuel injector testing, one of our technicians will disassemble the injector for a thorough going-over. They’ll perform a series of pressure, spray pattern, leak and nozzle clatter checks, in order to make sure it’s functioning as is expected.
Informative Reports and OEM-Quality Replacements
We’ll issue a pass/fail report at the end of testing, and we’ll explain why any injector that doesn’t pass failed. We also have a large stock of injectors to replace any failed injector with.
