Hi guys , after some ideas for trouble shooting. I recently replaced my 1kzte head with a new one .i only removed the head and left the block gbox in the truck . It now won’t start and just clicks from the starter motor and the relay . I’ve swapped both , plus tried a different computer . Good batteries. It’s annoying me cause I parked it 3weeks ago running . Any things to check? Cheers Kev ,chch NZ
