If a 1997 Nissan Maxima will crank but will not start, there could be a problem with the fuel pump. Another possibility is an issue with the ignition switch.
A bad fuel pump will cause your vehicle to not start or sputter and then stall. A dirty air filter can have the same symptoms.
Start with replacing the fuel filter.
