Got a '99 Renault Clio 1.4 in at the mo, engine code E7J fitted with a siemens Sirius ECU. The car is a non-runner. The fuel pump is running but there's no spark and no injector signal. When I've read it with my Launch I'm getting fault code DF271 Actuator relay output voltage. Open or short circuit. This will not clear.

When I've had a look on the live data I'm not getting a engine speed signal when cranking  although when I've scoped it I'm getting a good signal both at the sensor and ECU pins but I've no other pin data for this ECU.

Can anyone offer any help?

What Renault call an actuator relay, we all know as an engine control/system relay. It is mounted in the fuse/relay box next to the battery, you may well find that water ingress has caused corrosion and an open circuit.

If there is no corrosion check the continuity of the wire between the ECU and the output terminal of the relay.

The difference a bit of info makes!!!!

Once Ian kindly pointed out that the actuator relay was infact the main relay then I was able to take a closer look. Although the relay hadn't taken water in one of the wires off it looked green and powdery. I cut into the loom and found it had broken around six inches in. Interestingly (for me at least) this wire had been repaired before further down. It had to be said we seem to be getting a lot of Renaults with broken looms, the wires look very poor quality.

many thanks for the info

Steve
