I have no spark in my 1988 honda what could be the problem?

Replace the Ignition Control Module (ICM) and coil. Be sure to coat the back of the ICM with heat transfer silicone grease.

Are you sure there is no spark? Or, is the car just not starting? If it's just not starting, you may have a fuel pump out. Sometimes also a fuel filter could be clogged too. (Just thought I'd ask) If you know for sure there is no spark, I'd try the coil first. Those are typically a lot cheaper than an ICM. (Most electronic items are not returnable either if for find that the ICM is not the problem) If no spark after replacing the coil, I'd try the ICM as the last thing.
