1999 Nissan Maxima 6 cyl Automatic 138000 miles

car wont start, i have tried jumping it, that didnt work, i replaced the battery, still wouldnt start, changed the spark plugs, still no luck. the engine tries to turn over, makes a rev rev sound , but it wont catch... what else could be the problem? should i look at the alternator or the catalytic converter?

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
