Omega A doesn’t start!

Well, it’s about an Omega A 2.0 with 85kw, year 90 One day (without notice) he didn’t jump any more. Engine turns, but doesn’t even start to light (no single twitch). The following points have been checked so far: – Candles: Are wet (although gasoline), normal candle image – all candles have sparks – mists fuel mixture (smells at least like this and looks like that) to the candle holes – don’t jump on with start pilot (no single twitch) – Timing belt normal and intact – Gasoline sufficient in tank – Air filter new – Safety fuel injection intact No immobiliser available. Compression not yet tested, but until the last stop of the engine it has run impeccable and unobtrusive. Does anyone know a typical omega patch in this direction or has an idea? -Does the petrol pump normally run briefly when the ignition is switched on at the omega to build up pressure or only when the engine is rotating? Thank you in advance! Your Stevie
