Boosted with a booster box heard pop under hood now cranks no spark no start

Find the blown fuse (the 'pop' you heard) that you missed before and replace it! ... Don't forget abou them big fuses! Best to TEST every fuse you can find on the truck using a test light > key on! .. Takes about 5 minutes tops... Remember >>>> POSITIVE to POSITIVE & NEGATIVE to NEGATIVE >> Even for a split second! https://repairpal.com/diy/how-to-jumpstart-a-car
