Odie you're in Copperas Cove correct? Temple isn't that far away, Garlyn Shelton Mercedes on HK Dodgen Loop can get you the primer pump if they don't have one in stock. Or you can always call the 1-800-for Mercedes number and have their roadside tech come out there with his own big battery and help you start the car. It's free. Don't mention to them that it's been sitting, though it probably wouldn't matter. Starting a diesel benz that has been sitting over a year SHOULD be a piece of cake.
