Even if the CSV is not working, once started and running, your use of the throttle to keep the engine at idle is indicative of another issue, likely out of spec cold control pressure--that's why you need a gauge set before anything else. The CSV only works when the start circuit is engaged, meaning when the engine is being rotated by the starter motor. Once you let the key move from the START position, the CSV stops injecting fuel.

Let us know about the cold start without the throttle. Does the engine fire and immediately die?
To clarify. Yes, I have to give some throttle to get it to start, when cold. (No throttle needed when warm) So I most likely have a CSV problem.

But, like you say, there is most likely another issue. I have to give some throttle to keep it running for the first minute or so after starting. With the throttle I can keep it steady at 1000 rpmīs. After about a minute, while keeping the throttle in the same position, it revs up to about 2000 rpmīs. I can then let go of the throttle and it idles fine. Runs a little jerky on low rpmīs until fully warm.

I will be getting fuel pressure gauges, but if there is anything I can try until then, (without changing expensive parts at random) advise would be appreciated
