[QUOTE="Dzchey21, post: 816063, member: 63"] got a truck, just put glow plugs, checked harnesses, gp relay ect on and its hard to start after it sits for a couple days. Nothing seams to help other than just flat out cranking on it untill it will start, eventually it will start but run very rough and then eventually smooth out once its warm, If its started if it is ran every day its fine but about 3 days of sitting and it will go back to not starting Only code is a p1670 which is IDM return or something like that. While starting sometimes it smokes sometimes it doesn't, it shows 370 rpm cranking with a dashdaq, icp is around 500 if i remember right once its running rough if you do a contribution test it will throw a bunch of injector codes and everytime you run the test its different cylinders eventually knocking out one cylinder every couple min untill you only get number 8 showing a contribution and the truck runs fine. Im leaning to the IDM but it doesnt really make sense. I already checked the idm relay and fuses and they are all good. i have also bypassed the GP relay and it doesnt effect it, when you first crank it barley even sounds like it wants to start, eventually the longer you crank the more it comes to life before it will finally start and run. any help will be cool, i think haller has a test idm im going to try but wanted any other advice before i dig into it. truck is bone stock other than a ww2, no tuning or anything like that [/QUOTE]
