Giulietta Start-Up Troubles Point to Ignition Mystery

Had the same starting issues on my 2014 Alfa Romeo MiTo diesel. After multiple attempts to diagnose, it turned out to be a combination of problems. The key turn symptoms matched exactly, rough starts, stalling, and inconsistent ignition response. The root causes were: Faulty crankshaft position sensor, Corroded electrical connections in the engine control unit, Clogged fuel filter affecting fuel pressure The car electronics diagnosis showed error codes pointing to multiple systems. What appeared as a simple ignition switch problem was actually more complex. The dashboard light patterns during starting attempts were key indicators that helped identify the real issues. The crankshaft sensor was the main culprit causing the rough running and stalling. This was a serious issue that could have led to complete engine failure if left unaddressed. The repair required specialized diagnostic equipment to properly identify all contributing factors. Worth noting that in these diesel engines, starting issues often trace back to the fuel system rather than just the ignition components. Getting a complete electronic diagnostic scan is crucial for accurate troubleshooting.

Thanks for sharing your experience with the MiTo issues. Your symptoms sound identical to what I faced with my Giulietta. Since getting it fixed, my car ignition system has been working perfectly, instant starts and smooth running. Curious about the repair costs you faced. For reference, my crankshaft sensor replacement plus labor came to 320 Euro, while the full diagnostic work was another 95 Euro. The ignition coil testing was included in that price. Has everything been running smoothly since your repairs? No warning lights or starting issues coming back?

Since fixing the ignition switch issues at the mechanic, my MiTo has been running flawlessly. The car electronics diagnostic revealed several problems, including a blown fuse that cost 52 Euro to replace. The ignition key now turns smoothly and the engine starts perfectly every time. The total repair costs were higher than yours, around 520 Euro including parts and labor. This covered fixing multiple electrical issues affecting the ignition coil and connections. But considering the potential damage that could have occurred, it was worth the investment. No warning lights or starting problems have returned in the 8 months since the repair. The car starts instantly in all weather conditions. Just make sure to get a full diagnostic scan if you notice any changes in starting behavior, as car ignition problems can indicate deeper electrical issues. Keep monitoring your Giulietta for any recurring symptoms, but it sounds like your mechanic found and fixed the root cause successfully.

Thanks for all the advice! I finally got my Giulietta properly diagnosed and fixed last week. After seeing your replies, I insisted on a complete diagnostic scan rather than just accepting the initial ignition switch theory. The mechanic found that my starting issue stemmed from a failing fuel pressure sensor and damaged wiring in the car electronics system. The total repair came to 475 Euro, including the diagnostic work. The dashboard light warnings have completely stopped, and the ignition key now works perfectly every time. The experience taught me to be more thorough when dealing with starting issues. What seemed like a simple ignition coil problem turned out to be more complex. Really glad I pushed for that complete inspection instead of just replacing parts hoping to fix it. Now the car starts instantly and runs smoothly, no more rough idling or stalling. Should have done this months ago instead of trying quick fixes that didnt work.
