Replace the Ignition Control Module (ICM) and coil:

Even though I suspect the ICM is the main culprit, I would replace the coil, rotor, and distributor cap, while you have the distributor open. If the problem persists, replace the main relay. I have never seen a Honda fuel pump fail, even though many people replace them.

I already changed the distributor cap and rotor.whats the icm

The Ignition Control Module (ICM) is a small computer inside the distributor that controls when the coil sparks. The ICM needs to "fire" exactly when the Engine Control Module tells it to. ICMs are notorious for failing on Hondas.

This is what the ICM looks like and costs:

Make sure to coat the back of the ICM with silicone heat transfer grease or it will shortly fail.

Thanks 2 people have told me with you is the 3rd thank I'm going to get that done I'm going to have to take the part out don't know if my motor is 1.5 or 1.6 thanks ill keep you posted

Where is the coil located I got the icm

Inside the distributor. Some of the wires from the ICM will run to the coil. Look for the coil spring electrode.

Txgreasemonkey I took the icm to my mechanic and he advised me to buy the entire distributor.but he needs the car when is acting up cause since we spoke in here the car has been turning on and off good your opinion.please let me know

If you decide to go that route, buy a genuine Honda distributor. We have had many problems on this site with aftermarket distributors for Hondas. Because of the mileage on your Civic, replacing the distributor housing is a good preventive maintenance move. The sealed bearing in them is prone to failure--mine went at 95,000 miles.
