Kalos Intermittent Starting and Stalling

Having a nightmare with my 2009 Chevrolet Kalos (gasoline engine). Just hit 212570 km and now it won't start half the time! When it DOES start, it idles super rough and sometimes just stalls. The check engine light is on constantly, and my gas mileage has gotten way worse. I even got an error code read. Could it be the fuel injector?

Summary of the thread

A 2009 Chevrolet Kalos is experiencing intermittent starting issues, rough idling, stalling, a constant check engine light, and poor fuel efficiency. The initial suspicion was a faulty fuel injector, but further discussion suggested a potential problem with the fuel pump or its relay. After professional diagnosis, the issue was identified as a defective fuel pump cable, which was replaced, resolving the problem.

Sounds like fuel delivery issues. A faulty fuel injector could cause some of those symptoms, but with all those problems at once, especially the no-start and stalling, I'm leaning more towards the fuel pump itself. Have you checked the fuel pump relay or listened for the pump priming when you turn the key?

Fuel pump relay? Where is that even located, and how do I check it? And how would I listen for the fuel pump? I'm not really a mechanic, just trying to save some money if it's an easy fix.

Given your symptoms and the error code, it sounds like a defective cable or plug connection. It's probably best to take it to a workshop. They can properly diagnose the fuel pump and its wiring and connections.

You were right! Took it to a shop, and it was a defective fuel pump cable. They replaced it for 95€. Runs like new now. Thanks for the help!
