It was running perfect. Stopped and put fuel in it and drove 10 mile stopped again and would not start back. It has 143k miles. Dealer said it has only 300 psi of fuel pressure and the injection pump is bad. Just wondering if there is another problem somewhere causing it to not have the correct fuel pressure. Any help would be greatly appreciated.

It is one of your pumps. It is most likely the injection pump because if it was a lift pump, then it would probably still run somewhat. I had a 6.5TD and it had fuel pressure problems. It was the lift pump that quit though and it still ran it just had low power. After you get your new pump put on i would start putting some high quality ashless 2 stroke oil in every tank. It will lubricate your injectors and pumps and make them last longer. 8 ounces/10 gallons is plenty.
