John and all,
The KL22 pump was installed last week and works but the drive circuit in the car doesn’t and may have been damaged by the failure of the old pump (which doesn’t work). So I am looking for a second-hand ECU (Engine Control Unit) Part Number: KFA218881C.

Are you sure it is really the ECU which is defective?
Would recommend you the following:
1.) give the fuel pump external power
2.) try to start the engine

It is possible that an engineer here can repair the original ECU but he does not have a circuit nor a fixture (test rig) for it; he will not be here until Friday and I will be looking for a replacement before then, without much hope. Are there any in Germany, I can barely cope with your site and would be unable to use your eBay properly?

Yes, there are companies (in germany), which can repair ECUs.
Please keep in mind, that your Xedos does have an immobiliser system. It means, if you change the ECU you need to "teach" it to you car.
Means following sections need to have Authorisation to work together:
- ECU
- immobiliser control unit
- key
So if you only change the ECU, you need a Mazda dealer who can do that. Or you need to swap all three parts from same car.
Good luck!
Let us know your progress.
