Finally got back round to the rs. I managed to get another yellow sensor and now the car runs with the pressure actuator plugged in. Problem now is, from cold it will start on the 5th injector then die. Ive adjusted the mixture as best as I can at the moment and will try again from cold tomorrow.
The yellow sensor i got was used and tested about 2.5k ohms at ambient temperature (about 15 degrees C). Is it possible that the sensor range isnt good enough therefore not fueling correctly for a cold start? As you know these sensors are very hard to get now.
Thanks
