You can't do it properly without the engine running. The voltage with the engine off doesn't matter. The only reading that matter's is the voltage taken with the engine running and other electrical accessories on.

You also need to jumper the yellow fuel pump check connector in the engine bay before you'll get any reading.

hmmm. it will still start up though if i do it right whont it?im just worried i might have mixed up the blue/w red strip on it and when i get my new engine in it whont fire up because of that. couldnt i just test it to see if its getting power at all just to see if i did it right because im pretty worried

Yep, if you get 12V you're sweet. You need the alternator charging the system to measure the improvement though.
