Fiat Scudo Cranks Wont Start
Summary of the thread
A 2005 Fiat Scudo with a gasoline engine was cranking but not starting, leading to suspicions of an ECU failure or engine software issue, especially since the engine light was on. It was suggested to first check the battery cable connections for tightness and corrosion, as poor connections can mimic major electrical faults. Upon inspection and cleaning of the battery cables, the vehicle started successfully, resolving the issue without needing ECU replacement or software diagnostics.

Good point! I did a quick visual inspection, but didn't really check them thoroughly. What exactly should I be looking for beyond just 'tight'?

Think of it like a garden hose. If the connection to the tap is loose, you get weak pressure, right? Same with your battery. Look for any corrosion (that white powdery stuff), cracks, or if the cables wiggle even when the bolt is tight. If they're not making solid contact, the ECU might not be getting the power it needs. If that checks out, probably best to get some professional engine diagnostics.

That's really helpful! Turns out the battery cable connections were indeed the problem. Cleaned them up, tightened them, and she started right up! Cost me 155€ in the end. Appreciate the advice!

Sounds like an ECU issue alright. But before you start thinking about a new ECU or software, check the simple stuff first. Are your battery cable connections good and tight? A bad connection can cause all sorts of weird electrical problems that mimic major faults.
