Double check the first plug on the ficm (farthest towards the front of the truck) , make 100% sure it's fully seated.After having the truck apart to replace a cracked oil filter base, re assembled everything, plugged everything back in. Truck doesn't start, no injector clatter. If i ground the FICM relay however as shown in the attachment it fires right up. Replaced relay and same issue. Any thoughts? View attachment 778571
Could be a bent pin also.
