Ditto comments on coil. If you have the old one, swap it back in. Why did you replace it in the first place? Report your results. If you still have the problem, we'll offer some more analysis. It does sound to me like an ignition problem rather than a CIS problem.
The 033 WUR is not from an OXS car, as you noted, it's from an earlier car. So, your CIS should work like an earlier CIS system. 24 Ohms is in the correct range. It should get 14-ish volts when the electrical system is charging, and battery voltage before the system is charging.
If you haven't tested for vacuum leaks, do that too. Old CIS systems often have vacuum leaks, which will complicate your troubleshooting.
