Hello to anyone that can help, My 03 duramax has 300k miles on it and has been sitting up for a few years. I started driving recently and notice several new problems; A. the engine starts up fine when cold but when I drive for a few minutes then shut the engine off it won't crank up without starting fluid. B. Smoke comes out of a port on the front of the engine while hot air exhaust comes out of the tail pipe. WHAT'S WRONG???
