AX Bj 93 Starting difficulties

Hello together.. Got there a little problem with the AX Bj 93 33kw of my sister-in-law. Short history: Morning car tries to start without success. Was only a quick clacking from the engine room to hear. Error found in the fuel pump relay. Plug from rest was with clackers. So old relay out 2 days ago, today new relay worried at Fiat (the from the Ullysee also fit in, same switched, same connection. same part number) and in the car with it. g I had with it : The clacking was gone and the relay switched on normally. Now to my actual problem: Shouldn’t there be a (if I remember correctly) brown motor control lamp shining when switching on the ignition?? If so, what is it that does not light up and the engine does not start. Battery is good, 4 fuses in the engine compartment IO, fuses left fuse box IO, starter rotates diligently but I miss this control lamp of the E injection system, the buzzing of the fuel pump and the starting of the engine. If any of you can help me (circuit diagrams or similar) or give tips please post. Thanks already in advance. Greetings mirical1
