Cranking the starter but won't start (My Summer Car)

I downloaded the save game with the assembled stock car, it drove more or less, but then it started to go jerkily. I decided to take it to the mechanic to have it done. After the mechanic, she showed no signs of life, then charged Akum and now at least the starter was twisting, but then he died. I bought a new one, changed it, now the starter turns, but the car will not start. I changed all consumables, there is fuel. I climbed the whole Internet, but I still could not find a solution, maybe someone knows what to do with it?
