We Offer Electronic Fuel Injector Testing in Corpus Christi, TX, & San Antonio, TX

At Diesel Engine & Injection, our electronic fuel injector testing services cater to a range of diesel trucks, including GM, Ford, and Dodge models. Whether you need fuel injector cleaning, fuel injector service, or comprehensive fuel injection testing, we are your trusted partner in San Antonio, TX, and Corpus Christi, TX.

Cleaning & Testing Process

Our common rail injector testing is a meticulous procedure ensuring the optimal functioning of diesel injectors. We employ ultrasonic parts cleaners to eliminate carbon, dirt, and rust, preparing the injectors for evaluation. Specialized test machines assess critical performance factors, including coil resistance, full load delivery, idle flow, nozzle tip leakage, return fuel, fuel delivery, and pilot injection quantity. This thorough process guarantees that each injector meets the highest standards for performance and efficiency.

Replacement Process

When replacement is necessary, our team follows a comprehensive process. This involves careful removal of the injector pipe, back linkage, electrical connection, and retaining clamp. After removing the protective cap from the nozzle, the new injector is seamlessly fitted into place, with meticulous attention to reassembling the retaining clamp, electrical connector, back leakage, and glow plug. The high-pressure fuel pipe is then refitted using the correct tooling and torque, ensuring a secure and reliable replacement.
