G20 does not want to SPRING 🙁

Hello guys, so short and close….. I drove over the highway last Saturday (a week ago) the thickness went out three times. Just “dead” and rolled out! Then every time restarted and the ride continued, the 40km I got behind me at some point and put it away at home. Now I wanted to move the thickness last Sunday …… engine turns but the “sau” doesn’t want to start! Ignition spark is there cap and distributor clean, If I got him fuel in the “VERGASER” ( TBI EInspritzanlage ) he lives briefly. At the injection nozzles is changing voltage but does not work. fuses are all GANZ (the ones in the footroom). Now I am with my Latain at the end what should I look at? I have to say one of the previous owners has there also such an alarm possible. Imprisonment locks hurried into the electric but just as connected as it was when he was still running. to build them out (which I like to get to w I don’t think it’s so urgent, even if I don’t have a remote control or whatever for it. It’s a `91 G20 with 5.7L TBI injection Thank you for your help in advance! LG Sascha
