It has been very cold here 0 degrees had trouble getting it started yest then went out today and nothing at all .glow plugs come on radio plays fine i think it has power just not getting to starter for some reason

[Lilpooh]

Need more info!! What year truck? How old are the batteries? Did you check the batteries separately (disconnected from each other)? Have you tested the FICM? When were the fuel filters replaced last? What brand fuel filters?

[laith1]

2004 no idea on how old batteries i just got truck a month ago not sure what the
FICM is filters were suppose be changed when i bought it but not sure

[PGreenSVT]

Did you plug it in?

[laith1]

yes i did plug it in but not sure if working was very hard to start the day before but it finnaly did start

[jethro]

start by checking the batterys and replace if needed they should have a date on them. then if good check out the starter relay. if it starts then change the oil to a synthetic and then plug your truck in it will start alot better in the cold weather

[laith1]

where woud i find the starter relay sir and what is the FICM you refered to

[jethro]

ficm is the fuel injector contorl module and as for the relay idk in a 6.0 check the batterys first these require alot of juice to turn over
