Have you done a voltage drop test on all the cables? Maybe a new cable has a bad crimp at one of the ends, causing high resistance. Try cranking for about 10-15 seconds, then immediately fee for a warm/hot spot along the cables and at the cable ends. Also the starter and switch. Read the current draw with an inductive ammeter and compare with an A that starts properly. Do the same with a volt meter while cranking and compare.
