V40 1.8l does not start, no spark

Hello, I recently got a Volvo V40 BJ. 98 (probably Mj.99) with a 1.8l petrol engine (it’s the engine from the Renault cooperation) and a manual gearbox. He ran without problems until now until I put off the car the day before yesterday (until then no signs of bitching) and he just didn’t want to start in the evenings. Symptoms: – Symbol immobilizer extinguishes – Starter turns the engine but does not start – due to some measurements we replaced the crankshaft sensor on suspicion, but did not bring anything – As it looks no spark, measurements of the two ignition coils leave but suspect that it’s not on the coils – I still have a KKL cable lying around here and have worried about the test version of VOL FCR. Interestingly, however, I do not come to all the control units but – the engine control unit. Now I don’t know of course – the next thing is that it’s on the cable, the software or the control unit? – The safety for the petrol pump and the engine control unit is in order, the control unit is not on the control unit.
