No, it wasn't too cold

Yesterday I took the battery from my camper to my apartment. I live on 5th floor, and have no elevator, so this was not pleasant thing to do. I plugged the battery to the charger.

Today I took the battery back to the Volkswagen and tried to start the engine. The temperature was +16°C (61F). I tried a couple times. The engine didn't start. I thought that perhaps the solenoid valve on the fuel pump is broken. In such a case the fuel pump doesn't feed the fuel to the engine, which simply won't start. But I checked and saw that both the valve and the wire that is supposed to power it were operational.

I had two very good possible causes and checked them both. None of them was the cause of my starting troubles.

What now? I'm not sure. I might call Tomek in the evening, perhaps he can help me. He usualy can.

If there was trouble starting the engine in cool temperature, it would mean, that the engine needs general repair. It would mean, that the compression in the engine is very weak. It would also explain why the fuel consumption is very high...
