pull one ignition cable out of cap just enough to see the tip of connector and crank it, a spark should jump from cap to tip of wire. no spark means you need the whole distributor replaced. buy it from nissan or infiniti dealer, it comes with cap rotor installed and 12 mo 12k mile warranty, no matter who installs it. dont waste time with aftermarket rebuilt distributor, those are not reliable. https://parts.infinitiusa.com/
