like I said I just got the truck and I am not the greatest at the computer searching for things , I think that it is loosing its prime after I shut it off and then I try to start it back up and its just spins and the batterys are junk and just slow down, one I know is totaly wrong . I have not realy dug into this thing yet . I did fix a bad wire job the last guy did for the external pump, but i do not hear the in tank one running , The guy I got it from said he put a new injection pump on it ,I see fuel on the lines, and after seeing his wire job I wonder if it has a air leak. I didnot check for a draw on the system yet , Just thought I would get some ideas from You guys , A friend said that this was a great place to find help before I do something I did't have to
