ive now got a wiring diagram with wire codes and colours courtesy of auto data (its not the easiest to find on there also found in ecu testing a reliable feeds and earths test which ive carried out and theres no feed from the under bonnet fusebox/control unit on wire 1203yellow to the ecu, clutch switch,airflow etc
looking at the diagram of this unit (its quite basic) ive checked the fuses in the unit and the feeds shown and they all seem to be there but still no feed on the 1203 outgoing cable ive tried powering it with apowerprobe but the eml is still not on and the car will not start
im kinda thinking this unit under the bonnet may be faulty but anybody any ideas
thanks
pat
