V70 XC 2.5T no longer wants….

Hello, have the following problem with my wife’s vehicle, a V 70 XC 2.5T 193 Ps Mj. 98 Ez. 10.98. Vehicle ran very well until the last, no drop-outs, nothing. Now stood for 3 days, with the muzzle slightly upwards. Today I wanted to start it, but it doesn’t start at all. No matter if I give gas or still so long örgel. No engine control lamp on, no lambda on. I had it read out, no faults deposited, nothing. Spark of ignition comes clearly and powerfully to the candle, fuel pump runs audible (summates). Relais 103 fuel pump relays I have disassembled, looks like new, nothing to recognize under the magnifying glass, by unclean or broken soldering points. Currently I don’t get any fuel in the combustion room!? Someone’s idea how to proceed further? Where exactly is the engine controller sitting? Not that it got wet with the snow or so!? Many thanks already in advance!
