Do you have blinking red led at console when Arming car?
When looking for power at 50, you went from 50 to ground, correct??

Looks like K38 problems if no alarm

K38 is behind the dash cluster . upper/left section.. approx behind gas gage location...
Terminals to test/jump on that relay will be 3 and 1.. via schematic

Relay #s will be 30 for terminal 3 and 87 for terminal #1.
Those are circuit # on the actual relay..
