This really sounds like the routing is not correct. You should be going from pump to rails to regulator to tank return. The csv comes off the driver side rail as a side circuit. Is that what yours is doing? Pictures?

Nope.

1.7L cold start injector is like a T and has a slightly different fuel flow and routing vs 2.0l. It could be plumbed like a 2.0l (assuming a single inlet 2.0L CSV fits a 1.7L plenum??? Based on pic I think the flange is different???) but would result in more hose running around the engine bay to the frontside of the 1.7L plenum.

I posted the 2.0L fuel line diagram because I couldn’t find one for a 1.7l. Wanted as a graphic aid to ensure that the fuel pressure regulator was at the end of the fuel circuit and so we would have common reference points. I apologize for any confusion I caused by posting the 2.0L fuel line diagram.

Yeah, that is quite a bit different looking. Definitely just take it out of the system and see what difference that makes. I can't believe it would have a fail state that would stop fuel flow but looking at that t i would have to think it is possible.
