Recently my 2.6 has been stalling unless I rev the car and red lights to keep it from stalling. Finally I parked it in my driveway one day and it stalled completely and won't start. What can be the problem?

I replaced the spark plugs, distributor cap, and rotor. Engine turns but doesn't start. I suspect that there is no spark, tried pulling out spark plug #1 and there is no spark.

What other component should I look it? How else can I test for spark?
