Brother-in-law bought an 2002 Freelander that the motor did not work. They swapped a new motor on there and know the trcuk does not want to start. Do you guys have any clue in which would goes this?

 

below the battery bos is the main engine ground, big black wire, it bolts onto the engine, its the same thread as the bolts for the batt box, only shorter, if youre not paying attention when you put it back together you can get it wrong and it wont be tight and cause a no start... by the way, is this a no crank or a no start?... but ive seen people get that bolt wrong a few times
