1999 Cummins 24 valve , quadzilla , 100hp injectors, nv4500, air dog 150
when I try to start my truck with key half the time it will fire right up other half it will turn over for ever and won’t go .
dont believe it’s a prime problem as I checked for leaks and made sure everything was tight , you can turn truck off for half a second and try to start , just turns over
but if I roll start it , it fires right up no problem ???????
cleaned all batt cable ends ,and grounds
help please it’s geting annoying
