My 2010 Nissan Frontier will crank but not start

it's not the battery or the starter,the battery is doing its job,the starter motor is cranking the engine over. you have a fuel/compression/air or spark problem,testing required to figure out which one you are missing.

my brother just fixed this same issue. turns out it was a dead distributor electronic module of some kind. apparently very common problem. only fix is new distributor, but there are lots for sale and change-out job is very easy. be sure to mark rotor position, and you may need to remove an electronic module that will be in the way of your 12mm socket, or try 12mm universal, or 12mm wrench from below. remember to lubricate new gear(grease) and shaft o-ring(eng. oil). careful when pulling out old dist. and pushing new one in (rotor will turn because of helical gear on shaft). also use white-out to mark visibly the timing marks.

The 2010 Nissan Frontier 4.0L is not equipped with a Distributor!
