could be a few simple things, you can do a 3 key on and off and it will give you a code, could be the lift pump which are ez and need to be upgraded, factory calls for 10psi but for proper vp44 longevitiy 14-18psi is preferred, could be a loose filter or fuel fitting leaking, needs to have 2 good batteries and alternater, get an digital volt meter and check for AC voltage has to be less than .1ac or your going to have issuses with tranny and other electronics, also check every ground wire on body battery and there is a gray ground above the alternater that needs to be properly soldered and reground, also go to cummins forum and theres lots of good info there, check for exsseive blow by
