Getting a P302 code. Injector 2 stops firing sometimes. At a red light it just stops. Sometimes, if I turn off the car and crank it back up, it will work until I hit a red light then stop firing again.

Troubleshooting:
1. Swapped 1/2 plugs, wires, injectors. No change.
2. Bench tested injector 2. Works.
3. Spark test on cylinder 2. Have spark.
4. Unplugged / replugged injector 2 plug. Sometimes, it kick on, other times it doesn't.
5. Tested all 4 injector pigtails. 44.7, 44.7, 42.7, 44.7 Ohms

What can I test to diagnose the problem?
What's the injector resistor pack?
Could that be the problem?
How do you test that?
