Let it spark in the cylinder,it won't harm anything.
No fuel-air mix to burn with an injector disabled,but that does not matter.
Those engines(non-Honda) that share a coil between two cylinders do the
same thing;allowing a spark in a cylinder with no fuel-air mix.

The other guys are more correct . . Unplug the injector. No worries
about any backfiring, but you might still generate a 'misfire' code, but
so what? At least it can't backfire if there's no fuel/air mixture
present.

I was referring to chassis ground, like any part that's steel. Doesn't
matter anyway, but it's worth remembering. Honda spark has to go
_somewhere_ or it will go to the wrong places.

As mentioned in previous posts, my sister's 99 civic has a damaged valve on
cylinder 3 due to a timing belt breaking. The car is running, albeit poorly
due to no compression on cylinder 3. Once you rev it up, it sounds OK.

Would it be safe to drive the car across town to a different mechanic in this
condition? What are the risks? Or should it be towed?

The drive would be in the city, 50 km/h or less, and revved as low as
possible. Its about a 14km trip.

Please advise.

Thanks
