2.5L no start

Hi,
My 91 2.5L decided not to start today cranks ok, but will not fire . It rained very hard yesterday so that may have somthing to do with it... I pulled #1 plug and it has spark when cranking. I also gave it a shot of carb cleaner down the intake and it does not even make a sputter. If it has gas and spark and will not fire what elas could it be??
Thanks

spark may be weak... what color was the spark you had gotten?

The spark was sort of yellowish. Not sure if this is good or not... There was a lot of condensation all over the engine due to the 4+ inches of rain we recieved yesterday. I will open the hood and let things dry ovt later today and try again.

blueish is the color you want, spark may not be hot enough... but if every thing is wet, let it dry off first

opened the hood, dried everything out and now it starts fine. I guess I will replace the cap/wires.
