Elise S1 - won't start

[SWE 66]

Dear Lotus Elise S1 specialists.
My S1 just won't start. Happen during a short "pit stop". My initial thought was that the immobiliser was the failing part.
The engine just didn't react at all. As trying to start w/o using the immobiliser key.
I bought an "immobiliser by-pass" and connected this one.
Guess that happened? ....or not happend 😢
I can hear an silent click when trying to start, but not a sound from the starter or fule pump.

Where should I start to look? ECU or is this simply the starter?

Thanks in advance for any input here.

Thank's for feedback. I'll try this.
