Twingo C06, engine C3G, Bj 93, engine does not start

Hello, who can give tip. Twingo C06, Motor C3G, Bj 93,Motor does not jump on While driving engine became louder and then steam came out of the engine compartment. Visual test showed that coolant came out of the balance tank (cap) and coolant behind the V-belt disc of the water pump ejected from two openings. At the drive belt of the water pump teeth had gone off. Probably due to lack of water pumps drive the engine was too hot. Further test resulted: Starter spins, crankshaft and camshaft turn, valves move. Apparently no head sealing defect, because oil is fine. Petrol pump brings gasoline into the carburetor. OT dot encoder has the correct ohm value and ignition works. Vehicle has no WFS and no crash switch. fuses and two relays OK. What does it look like, no gasoline is injected into the carburetor despite fuel supply? Candles are relatively dry after starting attempts.
