Hey guys, I spent today pulling apart my engine learning Rx7 basics and all. The guy I bought the car off said he had the car running then he noticed a fuel leak, so he pulled the intake manifold to fix it reconnected everything and the car wouldn't start. I don't know what the guy did or if he did anything right but while I was pulling it apart I noticed the 1 antifreeze bottle on the pass side firewall connects to the fuel rail. I am a newb to Rx7's but is that really the way it's supposed to be??? Also I noticed another line connected from the lower intake manifold over to the brake booster??? I know I should've taken pictures all but....too late. Anyway am I missing something here or did he majorly screw shyt up?

 

its the subzero starting fluid bottle.

 

care to gimme a brief explanation as to how it works?

 

it doesnt... thats the thing lol.... mazda told their mechanics to rip it out if they had a car in with it... they discontinued the idea for the s5 cars... what it was "supposed" to do was inject antifreeze into the manifolds when cranking the car in temperatures below freezing to help it run or crank better.... like i said it doesnt work.. you can yank it out and cap the line or pull the unit off the manifold and buy a blockoff plate for it

and btw that line doesnt connect to the fuel injectors or the fuel rail... it connects to the manifolds.. thats what you need to pull of or c ap off if your going to remove it
