2000 Dodge Ram 1500 5.2 engine. 123, 000 miles. Will not start, sounds like it wants to and when it does start it idles like it's choking and cut off. New tires, battery, and just changed crankshaft position censor. It has quite a bit of rust on all fenders, at this point I don't believe it's drivable, I wouldn't try to drive it.
