i have a 91 accord that had a F22A4 and i replaced the engine with a F22A1 they both ran before i swapped them now after i put the replacement engine in F22A1 i have no spark i replaced the rotor button the cap and plugs and wires after i did that without messing with anything else the starter wont work with the key so now im thinking electrical problem but i went all through the fuse box and wires i have no idea wat to do now plz help someone??

 

coil or icm? have you checked those?

 

yes i have two dizzys both test good as well as there internal coils but im new to hondas so where is the ICM??

 

could be your main relay?driver side under the dash

 

To answer your question...
ICM = ignition control module = slang term is "ignitor".
It's inside the distributor; it's kind of an isolation amplifier to prevent voltage spikes from the coil from getting back to fry your ECU.

 

And to add....check that the main ground - G101 - is attached/clean and tight. This ground is on the "lower" bolt of the t-stat housing for your 4th gen.
