350z won't start and floor brake pedal lock

[ruban]

Hello everyone,
Need help. Any kind of help and information will be appreciated.

My 350z (2004, Automatic) won't start.
Battery seems to be fine as all the lights and radio works good. Also I had it replaced less than 6 months ago.

This weekend morning i tried to start the car and it just wont.
Also found out that the floor brake is locked. I cannot push it down.

I have read about the pressure build under the brake line when car is not on but was not able to find anything to fix it.

It won't just start.

It would be great if someone can help me with this.
I cannot take it to shop as of now. ($ issue)

Please help.

Pull the shift interlock plug next to the shift stalk, put a long thin screwdriver down in the hole and push down to unlock the shifter, put it in neutral and try to start it. Let me know what happens.

Also, if there's no vacuum on the brake booster from the engine running, the foot brake is going to be extremely hard to press. Is it cranking over and not starting, or just not making any effort?
