Disconnected lines around cp3 and filled them with diesel. Reassembled and it fired right up! Mustve had air stuck in there. Btw truck runs way better now with new cp3. Idle is Much more smooth and a considerable amount of power gained back. 300k on old cp3 definitely had taken its toll. I disagree with waiting to replace it until i had issues. Especially due to mileage on truck, hard to believe its unheard of...but what do i know
