i had the tdc sensor and loom changed the cam sensor, dehaser ,timing belt kit, water pump and a service with sparks and filters replaced also had software update but still the same the car only has 29k on the clock

yes it was 1 of the 1st thing to be done with the tdc sensor

Ok. Next idea. When you cleaned the throttle body did you disconnect the battery and then go through the re-learning procedure when reconnected?

meganes do like lots of power and if its just not there it will take a bit to start

just a thought

If you switch on the ignition you should hear it whine then stop for 1 - 2 seconds. If you can't hear anything investigate. If it runs continuously, its in limp home mode, so investigate that avenue.
