So I have a new 2019 6.7, last night wife in way home , fuel display showed 55miles until empty low fuel light came on and with 1 mile truck lost power and shutdown, gauge still showed 55 mile until empty. I put 5 gals diesel in cycled key 3 time and it fired up and showed 178 mile till empty. Not good any ideas? Now check engine light came on. Truck has 3500miles on it.
thanks for any help
