Max Power 08-19-2004, 11:23 AM A friend of mine has a 2003 LB7 that is hard when it is cold it starts good. 45000 miles. He has a juice but no attitude. This just started a couple days ago. Any ideas? ThanksEdited by: Max Power Max Power 08-19-2004, 11:49 AM I just removed the juice and it does the same thing. He also changed his fuel filter and that never helped.Edited by: Max Power GMC2500HD 08-19-2004, 12:55 PM Possible pump failure? I think I was told something about that when I was having that issue. Changed filter and no issue since..http://www.dieselplace.com/forum/smileys/Confused.gif nassdmax 08-20-2004, 11:05 AM Could it be that he has some air in the system? Hot seems to exacerbate the problems with air. Just a thought... Zeeb 08-20-2004, 12:06 PM Hey Max, I was looking in the TSB section and found a link for NHTSA TSB look up. I was looking for stuff that might be pertinent to mine, but it seems like I saw something on the warm hard start thing...http://www.dieselplace.com/forum/smileys/Ermm.gif This is the link GMCSID posted: http://www-odi.nhtsa.dot.gov/cars/problems/tsb/tsbsearch.cfm Lots of stuff on there and it just gives a brief description, if you want research on a specific one, it's about $3.00 or something. You might want to take a look. Pharmkids 09-07-2004, 10:35 PM I had these same problems.
