(2) Debris on the coil
Inspect the coil for debris.The debris will be visible in the form of metal shavings on the coil. Refer to Illustration. If the coil is covered in soot, use a clean magnet to locate the debris.Note: DO NOT use high-pressure fluid or other cleaning solvents. Debris may be lost during cleaning.
If debris is present and/or an injector is inoperable perform the remaining Steps that are in Special Instruction, REHS3819, "Procedure for Troubleshooting and Cleaning the Oil Rail System for the Hydraulic Electronic Unit Injector (HEUI)". Ensure that the system is flushed through six injector bores, two large and six small plugs.
