1983 320 Jetronic no start

[BMW_E30vert]

Hopefully someone is familiar with the Jetronic system, I have an early 320 which does not start.

I believe it's a fuel related issue as some easy start will get it going, fuel pump hums and works when trying to start but it just won't kick into life.

Has anyone had similar issues or can pass some insight as to what to look for will be grately appreciated

Thanks in advance.

Also check the air slide valve, which are prone to seizing, though if this happens you usually just get a rather fast idle.
