Good/Bad news
Well I havent been posting on here for a while since no troubles for a long time. Today I decide to go to the dealer and have the batteries checked as the cranking has been slow. Well at no charge for me they replaced both batteries.Thats the good news. So we are going to the dunes for Thanksgiving tomorrow and decided to read the codes.Came up with a P0611. Bad news? I'm not sure. Does anyone know what is wrong to pop that code? Hopefully its not another FICM going out on me. Thanks for all input!

Here's your code:
No Start or Constant Engine Misfire:
There are several things that can cause this symptom, including a failed FICM (fuel injector control module). In cases where the FICM is at fault the condition should be present at all engine temperatures, and codes P0611 or U0105 may be set. If codes P2614 or P2617 are stored the cause is more likely to be a wiring chaffing issue. The harness will need to be pushed and pulled to determine if the harness is shorting out. WDS should be used to verify the injectors can be commanded on (injector buzz test) and that the FICM is powering up (datalogger PIDS FICM_VPWR: ignition power; FICM_LPWR: FICM logic power from relay; FICM_MPWR: FICM output power to injectors--47-50 volts). If an injector does not click during the buzz test, a test light can be installed between the injector connector terminals 1 and 2 and checked for illumination when re-running the test.
Sounds like it might be FICM again
Hopefully it's something else though.

There doesnt seem to be any misfire. I already had one FICM replaced,I can't believe I would need another. Last time the truck sat there and smoked like a SOB when you tried to get RPM's. No smoke at all now.
