04, 350 no start

[trickynicky17]

I was wondering if any of you guys could help me with my problem, the truck was sitting for two days i went to go start it and nothing just cranking not even an attempt to start. Ok so i figured the fuel must be jelled since its been cold, changed the filters and added antigel still nothing, checked the glowplug relay it was fine, fuses were fine, fcim was fine too. So i tried spraying silicone in the intake to see if it would at least try to do something and nothing. I also hooked a code reader up to it, nothing! Any ideas would be greatly appreciated.

Check the battery voltage while cranking. Also hook up a charger to the pass side battery. Let it sit for a few minutes and try to start it with the charger hooked up. If it starts its time for new batteries. Mine was doing the same thing, cranking but no start. Ford set a limit on how low the voltage can be. If too low it will crank all day but won't start. I replaced them and it started right up.

Awesome. Glad to hear it was simple. This site is the best. Daily reading will teach alot about these motors.

ok well the new batteries did the trick for a few days now it not starting again. I can run the truck all day it charges right at 14 volts shut the truck off let it sit all night go to start it in the morning and it cranks slow as hell?????? So i jump it and it starts right up Only thing i can think of is the new batteries are no good or i have something drawing current when its off?
Just figured i would pick your guys brains before i blow $400 on some yellow top optimas. Thanks guys Anyone out there have yellow top im interested how they are??

Man I am in the same boat. Truck started then turned off and has not started since then. I have checked all connections and they look good.(except the one behind the compressor, can't figure out how to reach it) taking batteries to Auto Zone tomorrow to have them checked along with the starter. I have seen SOOOO many post on this topic but no one can really point out what is the reason for it. Please hit me up if you figure this out! Thanks Randy

Running with low batteries is hell for this truck, you might have taken something else out in the process. I dont remember what it was that takes a dump (maybe the FICM?) but I remember reading someone having that problem. Check out the link in my signature for a troubleshooting guide

could be leaking through the high pressure system as well, get it pressure tested, when mine was doing that it was injector o-rings
