Hard Cold Starting

Hard Cold Starting
I have been having cold starting issues for a while. Temps have been nearing freezing here. It will usually stall a couple of times, and once it finally stays running it spits, sputters, shakes the whole truck, and wakes my roommates up, they're not too happy with me. I let it run for 5-10 minutes and when I drive off I have little power until the rpms get over 1500. When the truck warms up it runs great but if I'm parked and try to hold rpms at any level, 1000, 1500, 2000, or higher it will only hold them for a few seconds then start to hesitate. Coolant will boil over when towing or on a hot day. No OBD-II Codes. 2004 F-350 265000kms, fresh oil change, 15w40 Shell Rotella T, air filter, fuel filters. Any help would be very much appreciated. I'm totally lost here.

Have you had the pcm anf ficm mudule updated for the crank no start reflash.it induces heat in the injectors to help aid cold start up below 60 degrees.the injector gums up from a hot shutdown and causes the injectors not to fonction on cold start up.after the truck warms up it runs fine.you could also be having a egr cooler leaking coolant down the passenger turbo charge tube causeing it to load up on start up.id also suggest switching to 10w30 oil when it stays below freezing.this might help on the cold start up.thick oil dosnt like to flow well when its that cold.i think the reflash would help your issue.id give you the tsb but i cant find it.good luck.

10W30 is a good winter oil. 5W40 is a good all-around oil.
As IM-tech said, check your batteries and alternator and make sure they aren't weak. The updated flash sure could solve SOME of your problems. It is worth a try.
+1 for what IM-tech said about the EGR cooler leaking. Are you getting any smoke on start-up? Do you have any puking out the coolant reservoir cap (I am assuming you do when you say "boil over")? You might want to try getting an updated degass bottle cap (coolant reservoir). The old style will get weak after one or two episodes of "relieving".
To check for an EGR cooler leaking, look for white smoke and you can park your truck on a downward incline and pull the EGR valve and look for moisture.

the easyer way is to remove the right hand turbo charge tube,its the tube that goes from the exhaust manifold to the turbo, and pressure test the coolant system.with the raise the rear of the truck and pull the egr valve is you can hydro lock the engine and that would require you to remove the glow plugs.this is a pain in the rump.this is just the way i do it.the coolant will come right out of the egr cooler.
