Check these first

• A faulty fuel injector on cylinder 2
• An open or short in the cylinder 2 injector wiring
• A corroded injector connector on cylinder 2
• A faulty ECM injector driver for cylinder 2
• Low fuel pressure at the rail

What to do next

1. Read the cylinder 2 injector circuit on a scan tool
2. Inspect the cylinder 2 injector wiring and connector
3. Measure the injector resistance against spec
4. Check the fuel pressure at the rail
5. Replace the cylinder 2 injector if the coil is open or shorted
