I have a stock 1997 dodge ram 12 valve with a automatic trans that is getting diesel fuel in the oil at a very high rate. I have changed the lift pump so i no its not that. The only two things it could be now is the fuel pump or injectors but im not sure how to tell which one it is. The truck does not smoke or run bad once it gets started but it is hard starting in the morning. So does anybody no how i can test what it is that is causing the problem?
