Check for spark by spraying a good dose of starter fluid or throttle body cleaner into the air intake duct. Try starting immediately afterward. If car starts and runs for a few secs, then spark is OK and fuel delivery (Main Fuel Relay or Fuel Pump) is problem. If no start, the spark is missing and you have either an ignition switch fault (no power to the distributor), or you got a bad distributor.
good luck

All the info you need is in DIY forum section; download of manual, procedure to check ignitor, coil.
The blk/yel wire at the distributor should have 12V w/ keyswitch in ON position. If not keyswitch assy is bad and should be replaced. Again check DIY section for procedure and search will help find also.

Crank sensor diagnostics are also described in shop manual. It could be a bad sensor (check resistance of sensor coil), or possible damage due to improper distributor installation (distributor drive key installed backwards into camshaft drive slot).
I once installed my distributor incorrectly and got a code set because the mounting frame for the sensors was slightly bent when I forced the distributor key into engagement in the slot. I was able to repair by straightening frame and reinstall.

All the distributors from (nearly) the same year? Honda changed those sensors around occasionally, mostly after 95 or 96 or so.
Otherwise, you're right to suspect wiring. When the ECU throws code 8, it has no way of knowing the difference between a bad sensor vs. a broken wire.
