1. for sometime now my renault has not been starting up well especially when it rains on when the sun is out does it start up normally that is after about 6 seconds ignition and me pumping the accelerator.
Why are you pumping the accelerator? You have fuel injection! Sometimes people used to pump the throttle with carburettor engines, since this activated the carb. pump jet and made the inlet richer with neat fuel, but this only helped if for some reason it was weak, or the cold start device was not working. Pumping the throttle with fuel injection will have no effect other than to confuse the injection ECU! Six seconds to start suggests it is not good anyway even when dry, so you need to start from scratch and work your way through the obvious things first. Don't start looking for complicated answers until you have checked the basics.
If you are having problems starting with an injection system, and it is affected by damp - you say it is fine when sunny but a problem when raining if I understand you correctly? - then the fault lies either with poor H.T. and loss of spark, or poor connections in the electrics which are affected more when damp giving a loss of maybe a sensor signal. I assume the engine is spinning over quickly and there is good and even cylinder compressions?
So these are the areas that need checking first.
2. i tried jump starting it today
You must be very careful about jump starting vehicles with electronic ECU's. In fact it is not recommended, and I have seen too many damaged through this.
... and the gear is in i think third now it cannot move forward the only gear that now works is the reverse gear so i had to come home that way/.i would like to know how to fix that also the stick feels funny now its hard and stiff i also have a problem with my central locking system does not work any more.you press it it does not lock but u hear the sound.
Sounds like you have a gear linkage problem, so you need to check if it is external or internal. It may be something between the gear lever and 'box.
You will have to strip the door that is not locking to find out what has failed. If you can hear the solenoid operating, but it is not locking then something connecting the solenoid to the lock mechanism or in the mechanism itself has failed.
Finally when i am starting the car i have realized small amounts of smoke comes from the metal rope connected to the engine.
If you are referring to your engine earth strap, then you need to remove and clean all connections and maybe renew the earth strap, because if it is smoking it suggests a poor circuit, and this will affect all the electrics.
