Got off work this morning, and truck won'tstay running. It cranked, but will sit there and fluctuate for about ten seconds, then die. Crank Iit, goes rum-rum- rum and dies. Noticed the battery gauge doesn'tcone up. Didn't see the "wait to start" light either. Fuel press jumps up and down as it does this. Moving throttle has no effect. Been suspecting a computer going out for a while. Does that sound like it may be the problem?

Update. I have fuel press gauge. Fuel press good. Changed out the ecm. Now wts light works, lift pump cycles, but still runs the same. Will change out fuel filter and bleed, but will have to wait till tomorrow. Getting dark.

My truck just died also. A buddy of mine described the same symptoms you are and it was the injector pump. Check out this website it might be some help. http://www.bluechipdiesel.com/vp44diagnostichelp.html
