What is your question?
Even after the engine is completely rebuilt, and the engine runs fine I’m still not getting the number three fuel injector to fire. There is plenty of continuity between the injector and the ECM. All injectors are brand new. The ECM is brand new and was programmed at the local dealership, but for some reason, just the number three fuel injector is not getting any fire.
How long has your 2013 GMC Terrain had this problem?
More than a month

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. I understand the information you have shared, but my gut feeling is that there's a wiring concern. Utilizing a GM diagnostic tool to verify components commands and operation is helpful. If the injector is good and the ECM is good - there's nothing else left to figure other than software or wiring. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
