Hello all, my name is Nickolias and my brother jaime and i volunteer for EMT and Firefighter here in Pennsylvania. i recently purchased an ambulance, Ford 2006 E350 6.0, 3 weeks ago. i drove it from location to here PA fine. but let it sit for 2 weeks. i do not know how to start it. i have heard it might be too cold. i might need a plug that goes under hood but don't know what kind to buy to warm up truck. any ideas would greatly be appreciated. Ive never had diesel truck before. please help. sorry if this is a "dumb" question.
