Car stop running, code u0109

Hello and thanks in advance. While sitting in my car with heat on approximately twenty minutes on a cold day it just shuts down. I've checked all fuses and relays, good. I've changed the FPCM. I can hear the fuel pump running when I turn key but nothing. It cranks but won't run. Does the car need to be reprogrammed since I changed the FPCM? If so, how is it done. I keep getting the u0109 code
Please help me somebody!
