Skoda Scala Engine Problems

Sounds like a fuel delivery problem for sure. The engine stalling, rough running, and check engine light all point to that. Since you mentioned you've got higher fuel consumption too, that further supports a fuel system issue. Have you checked the fuel pump relay and fuse? Sometimes it's a simple electrical problem. Also, when you say 'error stored in the error memory', do you know what the specific error code is? That could give a more precise clue.

I haven't checked the relay or fuse yet, but I'll give that a shot. As for the error code, is there a way I can read it with a standard OBD2 scanner, or do I need something special? I'm trying to avoid a trip to the auto repair place if possible!

Okay, so a standard OBD2 scanner should be able to read the error code. It will give you a code starting with "P" followed by four numbers. Knowing that code will really narrow things down. If it is a fuel pump issue, and given you suspect a wiring problem, carefully inspect the connector and wiring harness leading to the fuel pump. Look for any signs of corrosion, damage, or loose connections. However, considering all the symptoms, and that you already suspect a connection issue, it might be best to get it checked by car mechanics at a workshop. It could save you time and prevent further damage.

Thanks for the help! You were right, I checked the cable and plug connection to the fuel pump, and one of the pins was bent. Straightened it out, plugged it back in, and she fired right up! Cost me 95€ for the diagnostic at the auto repair shop, but at least it wasn't a new fuel pump!
