Are you checking properly for voltage at the relays. If so and there is no voltage at pin 30 or 86 on the DME relay, then you may have a broken wire. Check the wires around the splice point back at the bulkhead. Check the wires that come from the splice point as 2 of them go to the DME relay. One of them is a thin wire 0.5mm and the other is 4mm.
