Grrr - So sorry.........
I went thru and checked over again. Something went wrong...here it is...
At starter relay:
87 - Continuity PASS
85 - Ground when cranking PASS
30 - Power at all times PASS
86 - Power when ignition in start position PASS
ALL FUSES have been checked - PASS
The first time I tested this, I didn't do it right. There is power all the way through the really from the ignition switch. But what I want to make sure of is 87...continuity to what?
SOOOOO SORRY.

Not made up results. So sorry. It was my mistake. I am now using a multimeter set to the right option for all tests. I'm sorry. I don't know what happened on the first time thru. And I did check continuity just now from 87 to starter with the right setting on the meter. And there was zero resistance. Please accept my apologies.

All right. Obviously, I am a moron. Here's what's REALLY happening at the relay. Had a friend verify with me. Taught me something about it all...here goes...
87 to solenoid. Continuity PASS
86 to 50 ignition switch in position III: Continuity and provides power to 86 PASS
30 has power, but 0.76 volts. very little. PASS?
85 to ground continuity when ignition switch in position III. FAIL. Did I get this right by checking for continuity at cranking position?
87 no power at ignition switch position III. (and this, I think is expected if 85 fails, right?)
If you still have any compassion after this, please advise. Thank you for your time. YOU'VE BEEN REAL REAL GOOD THROUGH THIS WHOLE THING.

By power, I mean battery voltage. .76 volts is not what you're looking for at 30. So you have no power to the relay.
85 should be grounded by the CEM during cranking.
87 won't have power because the relay does not have power or ground.
You said you checked fuses, but I would double check fuse 13 under the hood. That is what supplies power to 30 on the relay.

Starter not engaging
Hi I was reading up 9n this issue and following your procedure and it appears I have no ground at 85. I assume I'll trace that wire to origin and clean or repair to solve ground issue? Thank you.
