Try this. Ram Diesel Manifold Heater Problems

 

when cranking what kind of smoke are you getting out the exhaust? If any?

 

there isn't any smoke. it will crank over real fast just won't start unless you roll start it. Thanks there is alot of good info on there that will help.

 

no smoke there is no fuel. with the rolling start its probably running off the lift pump. the vp diaphram inside the head of the pump are known to crack

 

I didn’t catch this double post from you before and WOW.....that’s a lot of codes. The reason I saw this post too was that I was checking to see if you referenced new batteries, and you did but I have to say that one indication of poor battery condition is no starting when cranking. This is because the pintle valve in the VP needs at least 9 volts or the VP has a hard time functioning. Trying to crank over the Cummins in cold weather creates a large amperage draw in the electrical system and therefore has nothing left for the VP to fuel properly if both batteries aren't in tip top condition. This is why roll starts help since then the amperage is much higher due to the lack of engine cranking. So aside from the numerous problems your truck obviously has, I'd again check to make sure those "new" batteries are perfect and possibly one didn’t go bad on you unexpectedly. They should also be both new and the same exact battery. Dont mix and match. Then maybe your battery cables are bad or your grounds are bad or the cable connections are loose. If you live in a high corrosion area then I seriously look over every electrical connection.

 

All of your codes point at your voltages being too low... maybe you have a shorted field coil in your starter causing it too draw excessive amperage when cranking. but lets hope its more like a corroded cable or such.

 

it cranks over real fast though it isn't draggy at all and the starter is about a month old. i was hoping that was my problem to thats why i went and bought two new batteries and the starter but didn't help it. got a little over 40 today and it fired right up the wts light didn't come on though if it gets below 40 it won't start at all. i cracked an injector line and it was squirting fuel so im leaning toward the grid heater since the wts light is acting funny and the heater isn't getting warm to the touch but i could be way off from the problem idk. if it is squirting out the injetor line shouldn't it smoke when trying to start? it is about 20 here now i went out to try it and the wts light came on for about 10 seconds then went off but the volt gauge didn't move and of course it would't start.
