12 is normal when you short the pins...nevermind that one.

34 is MAF low airflow or something...you said you changed your MAF so i assume the problem went away?

When did you check your fuel pressure?
When you just flip the key for priming its the same as being at WOT (no vacuum) it should be roughly at 42-44 psi.

If you checked it at idle it will be considerably lower.
