92 civic hb no spark

I just droped in my jdm d15b and it turned on fine and was running nice. But all of a sudden it just turned off. I still show a 1/4 of a tank and the car wont start any more. The engine turnes over when I turn the ignition but it wont fire up. I checked the spark plugs and saw that they are getting fuel so the fuel system isnt the problem. I found out that the spark plugs are not sparking all of a sudden. I changed the rotor button and distributer cap and I still have the same problem. Has any body had this problem before?

Thanks for any help

ignitor gone bad?

I got it working, I replaced the ICM with the one I still have from the engine I took out. Just hope this one doesnt brake after a couple of minutes.

thanks
