Dodge Ram 3500 no crank no start issue potentially related to PCM failure after multiple repairs on Dodge Ram 3500

Some Dodge Ram 3500 owners report experiencing a no crank no start issue that persists even after multiple repairs, potentially linked to PCM (Powertrain Control Module) failure. These owners have noted that communication problems with the PCM can lead to significant starting failures or performance issues, such as stalling or entering limp mode. Additionally, various electrical components, including wiring issues, blown fuses, or faulty connections, have been identified as causes of starting problems. Some owners have also encountered engine-related issues that prevent the truck from starting. The presence of Diagnostic Trouble Codes (DTC), particularly the P0320 code, indicates a lack of crank reference signal received by the PCM, which is crucial for ignition timing and fuel delivery. When troubleshooting, it is essential to check power supplies to the PCM, especially if there is no spark or injector pulse. In some cases, a break in the 12V battery power cable leading to the PCM has been reported as a potential issue. Owners experiencing these persistent problems are advised to thoroughly inspect the PCM and consult with a qualified technician or dealership for further diagnosis and potential replacement.
