white smoke from 06 6.0

[maroonf250]

I have a 2006 6.0. I have replaced my head gaskets. I have put the head studs on also. I had the egr delete put on their. I have had many problems with this truck. I just got it out of the shop replacing the tranny. Now when i crank it up on a cold start it is blowing white smoke bad. When it warms up to the normal temp the white smoke will stop and can drive it all day without seeing it. truck also runs fine. Also my battery seems to want to die easily when i try to crank it up. I also smell a strong smell. During the summer i do not have this problem. I have had several mechanics tell me something different and dont know what to trust. Can anybody help?

Check the FICM voltage while cranking but make sure both batteries are charged really well or just replace them both with 850+ cca units. Just by your description, your FICM voltage is low and bad or weak batteries will kill the FICM.
