2000 stratus 2.4l died and won't start. help me please

I was driving my 2000 Dodge Stratus se with the 2.4 in it and it died. Now i changed the spark plugs and the car is getting spark. It turns over but won't start. The timing belt is fine with no teeth missing. Does anyone know what else it can be?

Check the fuel pressure,it could be the fuel pump.

check the fuel pressure like wafrederick said. could be fuel filter or fuel pump.
do you have any codes stored? how many miles does your car have?
you could check for compression too although even if a cylinder or 2 had bad compression it will usually start but run like ****.

you mentioned you changed the spark plugs and now it is getting spark, did you not have spark before?
