Reset the security system after changing the batter - diesel Ram

question edited for clarity.

Some Semi work on 24 volts!

An overwhelming majority of Class 8 commercial vehicles in North America operate on a 12V electrical system throughout both the tractor and trailer. In some instances, a 24V electrical system is in place. However, there is a potential shift looming in the not-so-distant future to higher voltages.

Probably need to do anti-theft reset, but have a feeling a module is damaged because of the Semi voltage.

Could be the security is set. Lock it up all doors. Use the key to open the drivers door. This should reset the security.

computer in your Dodge truck generates and stores error codes related to critical vehicle component systems. When your Dodge truck generates one of these codes, a Check Engine Light will illuminate on the dash. This light can indicate a variety of problems. Ironically, only several codes pertain to the actual engine in your truck. Many of the codes can indicate a problem with the transmission, emissions control system and even the fuel system. To erase the code and get the light to go off, you will need to reset the computer. This will involve cutting the power to the computer. Instructions

1 Open the hood and loosen the retaining nut connected to the battery cable clamp that is attached to the negative battery terminal. 2 Slide the negative battery cable clamp off the battery terminal. 3 wait five seconds then slide the battery cable clamp back over the negative battery terminal. The Dodge's computer will now be reset. 4 Tighten the retaining nut on the cable clamp to secure the clamp to the battery. On some Dodge trucks, you will need to drive an additional 500 miles from the time you cut power to the computer for the Dodge's computer to fully reset.

This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.

It should be on one of the valve covers. I think it would be on the driver side one.

They are a pain in the ****. You have to take the valve cover off, remove the fuel lines, remove the inlet valve, remove the rocker arms, then unscrew the injector out. There is no doubt, that you can do it yourself, just leave yourself 3-4 hours probably.

I had the same problem on a 94 dodge with the cummins. It seems the crank sensor that reads from a notch on the harmonic balancer was the problem Without this sensor reading that the engine is running the alternator wont charge. Possibly the same problem with yours

Sir I can help you with this, I have all the service manuals on your truck and will provide anything you need, but this honestly sounds like a bad wire connection or ground on a primary battery cable. I would trace all my battery cables and clean every connection even the engine ground cable and the one at your starter. I will be glad to help you further, I can post step by step trouble shooting guides on your truck if you need them. Hope this helps.
