Yes, a faulty engine control unit (ECU) can lead to a no-spark condition in a vehicle. The ECU is responsible for controlling the ignition timing and firing the spark plugs; if it malfunctions, it may not send the necessary signals to the ignition system. Additionally, issues with the wiring or connections related to the ECU can also contribute to a lack of spark. However, it's essential to consider other potential causes, such as faulty ignition coils, crankshaft position sensors, or other components, before concluding that the ECU is the issue.
