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.
