procedure for testing for closed loop

I thought I had it understood the other day and jumped a&b (same pins I jump for codes) while the car was running and warmed up. The SES light gave 2 quick blinks and no more. Tried again with same results.

Was I doing it right?

The car is running super rich, hesitates from a stop until I give it more gas, turning all 6 plugs black, sucking down gas, losing fuel pressure when the pump stops priming, and I'm getting code 13 (lean o2), and I have a massive exhaust leak 10 in behind the o2 right before the cat, and a smaller header gasket leak on the bottom of the right side center tube.

If I could tell if it's going into closed loop it would give me some more to go on.

The engine is a new 3.4 with old junkyard injectors. The rest is all 89 2.8 maf stuff. I've been having this problem since I put the engine in.

Nevermind, jumping A&B seems to work now. Stuck in open loop.
