Ranger Mods

Firstly apologies if this is in the wrong place as I’m still finding my way around this great forum , I had problems with my bcm , more specifically headlights and it wouldn’t reset so assume it’s fried the bcm , got a good secondhand replacement , saved the as built info from original , installed new bcm successfully installed the as built and coded keys , only thing is truck won’t start , won’t turn over, only other thing is no mileage on dash am I forgetting something ? Thanks in advance

Did you do a PMI with Ford IDS when swapping the BCM? If not then have Ford do the PMI and module programming and it should be fine.
