No. You need to remove it and take it to someplace like Autozone or Advance. Here are some things you can test other than the IM while on the car; pick up coil and ignition coil.

EDIT: Technically, you can test it on the car if you have an ignition module tester with long enough leads to hook it up. But the normal DIY'er cannot.

Yes, just crank the engine, if the tach moves its sending pulses. I post the below file often.

Yourís could be a common problem and donít cost anything to check.
Try this:
Watch the tach when cranking if it donít move you're not getting pulses from the distributor. If so, it could be a faulty module in it or more likely simply corroded connectors at the base of the distributor. Reseating those connectors a few times could clean the pins some and also do the same to the connectors on the coil etc. These cars are old, and old connectors corrode. Such can also manifest itself as intermittent misfires, and engine cutouts.

BTW: lots of folks keep replacing modules and coils thinking they are bad because the new ones FIX the problem, when in actuality the fact that they simply unpluged the connectors and repluged them into the new unit cleaned the contacts enough to make it work again, at least for a while. It's smart, to replace those old connectors with new ones.
BTW: Cliphouse has those connectors
