Your dealer is correct that your problem has nothing to do with fuel injectors, it has to do with the Fuel Pump Module located above the rear axle, or no power to it like having a bad fuel pump relay. However, your dealer is wrong about it being a problem with the throttle body. Those 3 codes you posted all have to do with fuel delivery, or rather, a lack thereof.

 

I agree with alloro it has nothing to do with that recall, and the problem has something to do with the fuel pump or fuel supply, could be something simple like a loose connection at you fuel inertia switch

 

The fuel pump driver module is in a terrible location and it has an aluminum back plate which will corrode and allow the internals to get wet and basically fail. The code 1233 I believe is a code which tells the computer that the fuel pump driver module is offline or disconnected or could be broke. I was going to do pinpoint testing on this part until I removed it and it had no back, the circuit board was open to the breeze. It was raining out when it failed!! Be careful here because if the dealer wants to replace the pump, it is big labor and big dough for the pump. It took me an hour to change the driver module and the module lists for 110 I believe. It has been running like a top for a few weeks now and well over 1k miles. Did yours restart and half heartly idle?
