Hi,
The code, B0449 isn't for this specific vehicle, so I checked for a P0449. That is for the charcoal canister (EVAP system).
Do me a favor. At each fuel injector, there will be two wires. Each injector will have a pink wire and another that is a different color. I need you to check if there is power to the pink wire on the injectors. I attached a pic below showing the wiring at the injectors. All you need is a test light.
When you test this, place the alligator clip of your test light on the battery-negative terminal and probe the pink wires with the light. The key will need to be in the run or start position and you should have power at all injectors (pink) wire.
Let me know what you find.
Joe
