Don't give up just yet. There are a few more things you can do.

When you have the 2 relay sockets jumpered does the fuel pump run
constantly as it should?

The relay/fuse panel pin D15 burnout problem is only on 86-91 vans.
Earlier vans don't have that wiring arrangement.

The only role the ignition switch plays in this is to provide power on a
black wire from the key back to the ignition coil to power the coil, and
from there to pin 85 of the 2 engine relay sockets as well as power the
ignition module and hall unit. Since you say you have spark as well as
power at the relay pin 85 there is little reason to suspect the ignition
switch. Easy enough to connect a spare just to the harness and actuate
it with a screwdriver just as a test, to avoid the full replacement if
not needed.
