Depends on a few things. First the torque you put on the spark plugs is not an issue if you used the Honda spec.
If you did not change the Distributor cap and rotor recently that could be the cause of the problem. Next, is the Main Relay. There is a starting sequence for certain model Honda cars and this relay controls the fuel pump prior to start and afterward as well.
In the summer they tend to fail more often than any other time of year. Again this relates to older Hondas.
If you are getting fuel and spark it is time for a diagnostic test.
Just some places to check. Good luck.
