I am thinking about getting a 2001 Dodge 2500 , auto, 4x4, 360. He was asking $2500, I asked to see it today. He sent me a email and told me he is having a problem with the truck and did not have time to fix it so he dropped the price to $1500. He told me the truck will start and run then just shut down, like someone turned the key off. I went and looked at it and like it but need to figure out what the problem is, I did not buy the truck. He put a new fuel pump in and water pump [old pump was leaking] but problem is still there. He said the computer was replaced in 2013, when the truck dies there is a clicking coming from the fuel pump relay. I put my finger on it and I could feel it clicking. He said he switched the fuel realy fuse and same problem, why is it clicking? This happened 5 or 6 times, the truck would run for 30 seconds then stop. Does anybody have any ideas? One of the times the truck died I got under the truck by the gas tank and could hear the fuel pump running but it did not sound right. It would run then stop then run then stop, it would do this real fast like there is a short. After I left I started thinking, I think I can fix this truck. I sent him a message to see if he will take $1000? He called me and he is thinking about it, he will let me know later tonight. Wow! a 2001 Dodge 2500 4x4 quad cab for $1000. But, can I figure out whats wrong? Any ideas? The truck has 300,000 miles on it.
