check for the check valve that goes to the pressure chamber.

see if you can blow threw

 

there's no such thing as the pressure chamber are you sure you dont mean the vacuum chamber? because the check valve goes to the vaccum chamber

 

Dude, you are way off base here. You need to do some research. https://www.rx7club.com/forum/showth...threadid=98645 I've got some good info, and links in this thread. Read up.
And there is a pressure chamber.

 

the black plastic thing on top of the engine is a pressure chamber, not a vaccum chamber.

the vaccum chamber is almost impossible to see.
