To be clear, there is never any vacuum in the crankcase. It will only have an amount of pressure...(actually it better not ever have pressure on it, just out-gassing).. from what gets by the rings during compression and detonation. The only vacuum will be between the intake valves..well..the piston.. and the throttle body's butterfly plate. If your gauge is sensitive enough, you might also detect a hint on the air box near WOT and above 5K if you still have the stock intake pipe installed....and especially the prefilter bag over the end..dirty.

On solid with just the key to the run position but not running is normal-all systems check. Blinking in that condition and not starting means a major input error or systems fault, like a bad connection at the ECM, or bad ecm or at some primary harness or.. a short at the kill switch. Several other things as well. If just a sensor it would still start and keep blinking.
