    When no compression is mentioned, first thing to mind is a blown or bad head gasket.

    And are you sure your timing isn't off? It may be off enough that on the compression stroke the valves aren't closed, thus no pressure is built = no compression.
    ill double check timing tomorrow and make a vid for you guys and head gasket should be good changed that while i was rebuilding the motor

      if there is little to compression put a cap full of oil down each cylinder to semi seal the rings.some rings do not seal correctly till they get hot or you made all the rings line up in a line...

          That is an odd tone when you switch from accessory to ON.

          Do you hear the main relay switch on/prime the injectors (I can't tell from the video)?
          Have you checked your thermostat housing ground?

            Yep, zero compression. Your timing is most likely off. Can you get a pic or vid of your cam gear and crank(or flywheel, which ever one has the crank TDC mark)?

            As far as that increase in tone, that usually happens when the voltage drops on a timer IC. If your fuel pump priming is making the batt voltage drop that much, then you need to check your battery as well as your grounds.

            Edit: A few other things I noticed, all of your door indicators came on and it looks like your cluster dimmed a little. Your radio restarted when going from ACC to ON. What happens if you turn your lights, rear defrost, fan on high? Or just throw a multimeter on your battery.

              ^ Sh*t, I forgot this was the thread where he had zero compression (I'm not with it at all today).
              Near the beginning of the thread I mentioned checking voltage, did you ever do that?


              Seems like there may be a few issues you're dealing with (electrically) regardless of the zero compression issue.

                Are you 100% sure you had #1 TDC before bolting the head on? Just had a fellow member who rebuilt the motor and it didn't start. He looked at all his timing marks again and found that he had #2 &3 at TDC.

                  yeah i can definitely get all the marks in a vid for you.

                      Meter setting should be volts DC. I was thinking how did you get 27 volts from a 12v battery?? Then I saw the meter.

                      Second thing...I think someone else mentioned it. Your crank could be 360 degrees out since it spins 2 times for every one time of the camshaft and you could be lined up on that second half. This is easy to figure out:

                      Set your engine to the current TDC
                      Remove spark plug number 1
                      Place a screwdriver or stick down the spark plug tube
                      Rotate engine

                              Batt seems OK with no load on it, but we'll focus on the compression issue right now.

                              I meant to add one more thing after the screwdriver:
                              Watch your valves to make sure they make sense. (I.e. the intake valves are closing on the up stroke, opening on the down, etc.)
