Typical symptoms of a faulty DCM3.5 ECU
A damaged ECU can stop the engine from starting because the injectors receive no signal. The tester then cannot connect to the unit, and a measurement may show no power at the ECU despite good fuses. The failure can follow water ingress or a short circuit in the wiring.
The same symptoms can, however, come from a fault in the harness, power supply or sensors, so run a diagnosis before you buy an ECU.
