    Hello, so I have about 200k on my LMM duramax and it’s deleted and what not. I have never had a lift pump on it and I just bought an airdog but have yet to install it. I was just thinking, is it really worth it to have a lift pump especially this late in the life of the truck? I want the truck...

    I recently bought a 09 duramax with a fass 165 pump on it. I changed the filters on it today and didnt prime them. I turned the truck on which lasted for about 20 seconds now it wont crank over and the Fass pump wont turn on. The fuse is good on it. Any suggestions?
