does anyone know if a 96 ls intake manifold will work with a 90 throttlebody?cause i put those together and put it on my car and now it wont start.im not sure if its just that the intake manifold doesnt work or if the throttle body just doesnt work with the intake manifold any help would be awsome.

 

Is it just cranking and won't catch or it won't crank at all.

 

You mean a 90 B18A throttle body on a 96 B18B manifold? Sure, it should work fine.
