PONTIAC GRAND AM BLOWN FUSE PROBLEM

1994 Pontiac Grand Am • 170,000 miles

I have a ob1 connector but everyone I took it to that had the OB1 tester could not get the code from the computer, it kept saying "connect to the computer failed". What could cause this and how would I fix it? Is there another way to get the code from the computer via OB1 connector?

A paper clip corssed between A & B wil get it but if there is a connection problem that may be why or a blown fuse. Turn key on and count flashes of service light it will flash three times for each flash lie 1 then 2 is a codes 12 which is normal.
