This post is in regards to others about their engines starting and then dies. I was too lazy to read through all of the posts. My truck had this problem, it ened up being the little plastic bleed screw cracked and had a very small leak that allowed the fuel to bleed off after it sat a while. I just happened to notice it one morning when I had to pump it to get it primed. Sun caught the diesel and I was able to see it running down on the back side. The screws are around $19 if you can't get a discount. I hope this may help if anyone is still having this problem. By the way I am new to this site and plan on posting something in the welcome forum with some pics. :D
