ABSTRACT:
An electronic unit injector cross-wire detection system for an internal combustion engine including at least two pairs of electronic unit injectors includes a test signal generating device and a signal receiving device. The test signal generating device includes a signal high line and a signal low line, the signal high line connected to a first wiring harness connection location of each pair of electronic unit injectors of the engine for delivering test signals to a first electronic unit injector of each pair of injectors. The signal low line is connected to a second wiring harness connection location of each pair of electronic unit injectors for returning the delivered test signals. The signal receiving device includes at least two pickup coils, a pickup coil holding structure, and a signal monitoring unit. The two pickup coils are held in a predetermined spaced relationship by the pickup coil holding structure such that each pickup coil is positioned adjacent to a respective predetermined portion of a cover of the engine, each respective predetermined portion of the engine cover being proximate to the first electronic unit injector of a respective pair of electronic unit injectors enclosed within the engine cover. The signal monitoring unit is connected to each of the pickup coils and includes an output device corresponding to each pickup coil for producing an output indicative of whether a given pair of electronic unit injectors is cross-wired.
