It almost sounds like something between the ignition switch and the soleniod switch. Put a voltmeter on the battery, and while trying to crank - see if there's a load. If so, then your starter is most likely the culprit. If no load, then check the soleniod to see if the ignition switch is switching 12V to it. If not, then troubleshoot relays that are in series with the output of the ignition switch to the input of the solenoid switch.
I fix an Integra last week that had the same symptom. There was no switched
12V to the SS (solenoid switch). I could jumper the 12V to that terminal on the SS and activate the starter. I found a relay that had to be tapped on a few times...to jar the mechanical switch in the relay....and it's still fine.Good luck.
