Check fuel delivery to CIS first.

1. Is fuel filter saturated? (if not changed for a long time, change)
2. Both fuel pumps working/buzzing?
3. Remove fuel plumbing from pump/injection/tank, blow them clean with compressed air.
4. Check both pumps by measuring flow during 30 second run.

If part above checks out, it's time to troubleshoot the CIS. Start with measuring system- and control-pressure.
Thank you for your time,
