The PO628 means your lift pump has went bad. You can try hitting on it lightly and see if it will start back up. Many replace with an holly or equivalent aftermarket pump which is much better then the original. You can find info on the web to do this. http://www.dieselperformance.com/index.php/product/index/175P. The P2509 code sounds like one of your batteries is going bad. Have them checked out and see if they are fully charged and holding a charge. Also check to make sure the terminals are clean and cables are tight.

You might have an inertia cut-off switch that is either bad or just needs to be reset. The switch turns off power to the fuel pump after the vehicle has been impacted.

Safety feature for accidents to reduce chance of fires.

On Ford's it is located under the dash on the passenger side. Don't know where Dodge puts it.
