Official summary

PITSTOP: INJECTOR HARNESS ROUTING FOR PI1802Y/Z AND PI1803Y/Z ENGINE REPLACEMENTS - This bulletin provides information to address a no-start or hard start with poor running condition after engine replacement under PI1802Y/Z or PI1803Y/Z. Some replacement long blocks may come with pre-installed fuel rail, injectors, and injector wiring harness. If the condition is present, it is possible that the injector harness was not installed correctly. The connections may be swapped from cylinder No. 1 and cylinder No. 4, and from cylinder No. 2 and cylinder No. 3.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
