Check as follows:
- Test for improper injector setting.
- Compare the calibration code(s) shown on the Detroit Diesel Diagnostic Link display with the six digit calibration code(s) on the injector(s).
- If the calibration codes match, check compression pressure; refer to “9.5 Low Compression” .
- If the calibration code on the display is different then the calibration code on the suspect injector for that cylinder, the injector setting must be reset.
