Hello again. I have been working over the past couple of weeks on a cold starting problem on my 95 Disco but the problem keeps reappearing.
I have searched and followed other threads here and got some good tips - However.
I have replaced the thermistor - the sensor that sense the engine temperature on start up, the IAC (stepper motor), rotor, cap, high tension leads and today finally the fuel pump.
Aoll to no avail. When I can get it started it runs really great, idle is great, acceleration is great, etc. So replacing these was, ecspensive yes but, worth it. I bought it this past July and every bit of work done on it has improved it immensely. Sometimes I wonder if the previous owner serviced it regulasrly. But I digress.
The display shows error code 14 - thermistor. Thanks to apost by Robbie Donaldson in May my brother in law and I were able to interpret the code and try to clear it. The error code will not clear. We followed the procedure that Robbie posted but 14 keeps coming up.
When the engine is cold is the thermistor open or closed?? Does the thermistor case a richer fuel injection or just a greater quantity?? When the engine is warm does the thermistor stay in the open or closed position. To test the thermistor does it have to be open or closed for a positive circuit test??
We are looking to a circuit test to see if perhaps the thermistor , even the new one, is stuck, open?? closed??, and sending the wrong message to the ECU and thus the continung difficulties with the cold start.
Seeking assistance and advice. Thanks.
