My father was borrowing my car the other day and while driving it, the car suddenly stopped running like the keyswitch had been turned off. After having the car towed home, I looked into the problem and realized I had no spark. I was wondering if it is possible for the main relay to be bad even if the fuel pump is still working. I have verified the fuel pump turning on. Also, while using the swaptronic method I have installed a new coil and ignition control module both however didn't fix the spark issue. If the main relay isn't the problem I was wondering if anyone else had an idea.

Replace the distributor housing with a new one one from Honda. Internal sensors (CKP, TDC, or CYL) may be bad. Install your new ICM and coil in the new housing.
