1 When was your last oil change? (miles/approximate month if its been a while)
2 You may consider unhooking your ICP sensor wire from the ICP sensor. And seeing what that does. I think your at the point were we are going to need some diagnostic information from the truck.
oil change was done 100 miles ago. I just checked all glow plugs and all are working. I also did compression test and all are 450 except 1 and it is 650.. Now I will connect everything back up and pull the icp sensor connector off and see what that does. As far as everything else goes there are no codes.
well just tried to start the truck after sitting the weekend. Still has hard start problem. I disconnected the ICP and still same problem. but when I get it to start I have no throttle response.
