1994 Dodge Ram. I just solved my no start problem. New lift pump. Then I had a start and die problem. It was one of main fuel lines running under the truck from tank to front. Took it out and used mighty vac on it and it did not hold vacuum. Replaced it and it runs fine. Now I have a problem with a thump sound from right front tire. The two front tires are less than l year old. Cooper 245 75r 16. Any ideas on what could be the reason the tire is making this sound? Thanks. Recycool
