OK lads, some progress today. After a long battle I got the bolt from the sensor out and changed it. However before I changed it I looked at the pin 36 and pin 13.
I measured absolutely nothing and I was sure I was measuring the pins as I removed the white plastic cover carefully.
Got the new sensor in, bang resistance!! Measured the sensor that came out nothing at first. threw it in corner and measured a bit later; resistance.
It can still be the connector but at least I know where to look now.
Now I will see if it starts all the time, if not the connector will be changed over the weekend. It is definitely in this bit.
Thanks a million!!!!
