Sounds obvious but have you checked all the fuses? Relays are behind the plastic panel under the steering wheel.

The rac boy checked the fuese and relays said all working fine my worry is that when u plug the car in it is telling me no signal to ecm. Is there a relay for the ecm if so where is it and what number has got?
