ok one of the posts was the one i needed leaving lol,
i have took the drastic measure of buying a fleabay hot fix kit and yipeeeeeeeee it now works, paid £29.99 and came within 2 days, i got the better kit not the relay and resistor,
turns out this problem has been on the car before i brought the car, because upon untaping the ecu wiring loom near the ecu, i find out some nice dude has already chopped the temp sender wire and then put a join in it.
it seems that the relay i was asking about in the previous posts is the cheap hack job via relay and resistor, pulled out the relay i replaced upon instruction from the timer seller on ebay and all works still, even when the car is warmed up i can get glow plugs warming up and starts first crack of the key.
kit really well made and very pleased with it.
