Im still looking into it. Got the batteries tested again and they say there fine, but im not fully convienced they are. When it does it again Im going to used my Ford batteries to check if they will start it. If they work it will be one or both the batteries. If not, ill start looking at the injectors.

If it was the injectors, would it not be throwing some type of codes? My Ford doesnt have a code for injectors, but with them going it throws other codes leaning to think the injectors. Im getting no codes at all. As you made It sound, it would basically do it every day due to that issue. It rarely happens, and only when it freezes.How can I test Injectors?

No difference of how it cranks at all. And the first time it happened I cleaned the crap out of all the post and connections. Now you know what Ive been messing with, and why Im at a loss on this. All signs point to the batteries, but when they get tested, they show to be good.May just be this backwoods shop I went to not knowing what they were doing. May have to go a town over and hit up one of the chain auto parts stores and have them test them.And the batteries are about 4 years old.

Thats it. No hesitation at all when on the charger. Thats why it keeps bringing me back to the batteries, even though the shop is saying there good.

It cranks, but wont turn over. It will just sit there and grind as its trying to start but kind of like the fuel is not getting there. Was thinking to fuel pump to because of this, but if that was going out most likely it wouldnt stay running after it got jumped, and would prob happen a lot more often. Like I said, its very random, and only seems to happen when its cold.

Im new here guys, one of your moderators Rogan told me to get on here and ask question. So here we go.The truck is a 03 2500, with 288k miles as of now. For the past couple of weeks, not every day, it has been dead and had to be jumped. The times it has happened like this morning it was 30 degrees outside, so not that cold. Im in Texas, so cold doesnt happen to often around here.The batteries have been tested, and said to be good. When there on the charge box everything cranks up fine, so to my thinking the starters fine also. I dont know much about this truck, as im more of a Ford guy (forgive me), so im at a loss of where to start. All my knowlege on other cars has got me always going back to the batteries, even though they supposedly tested good. Now once the truck has been started up from the jump box, its starts as normal from then on out. Like I said this has happened maybe 3-4 times, and its not an everyday things.Like I said:2003 Ram 25005.9 cummins288k on the clock2wdAuto TransAll stockAnd never any major problems since new.Any input would be helpful.Thanks.
