Toyota Corolla 1990 distributor

Hello Guys! I have a Corolla '90 which has some problems with the ignition. The engine is 4a-fe. I don't know why, but there is no spark at any spark-plug. What can be wrong?
At the distributor there are 2 connectors:one is with 2 wires and the other one 5 wires. At first connector the red-black wire is with electricity but not even one wire from the other five gets electricity.
What should I check?
Thank you!

I would say the first things to check are your spark plugs, wires, distributor cap and rotor. If any of the above is bad, you won't have a spark.

all are OK! spark plugs and wires are new! anything else?

Hubby says to check the ignition coil, if everything I listed above is okay. He's pretty good with cars : )
