Question

I have a starting problem with my Rover 620 SI Auto. year 1993, at 63k. Symptoms, this is a starting from warm and at normal running temperature conditions. At -6* below no problem at all, but if you turn off say to fill up, after 20 mile run, which is also trouble free, it will not start. If you lift the bonnet and let out the engine compartment heat, after 10 mins it will start ok. I have heard this is a common feature on this car and is worse in the warmer summer conditions.

Answer

Hello and Welcome to justanswer...

 

From what you describe it seems you may have a faulty ect sensor . This is the engine coolant sensor... This sensor tells the ecu - the management computer the temp of the engine and the ecu fuels the engine accordingly -- hence if the sensor is faulty , as is a common issue - the ecu fuels the engine all wrong and causes mainly starting problems.

 

The ect sensor is quick and easy to change and fairly cheap so it would be worth doing that straight off....

 

After that - IF you still had troubles - you would need to have a diagnostic test done on the car to see whats going on diagnostically... but Im honestly sure the ect sensor is the culprit here..

 

I sincerely hope I have helped you ~ please ask me if you need more help..

 

Best rgds... MIKE
