indications are that they are
hard starting when cold indicates a problem ambient temp sensor or BARO sensor
These sensors report to the ECM so that the correct air/fuel mixture is set for cold starting and running---sort of like the old fashioned choke pull
have the fault codes read to determine where the faulty sensor is

indicates a fuel pump problem as that is the only thing in that area that is ignition controlled or possibly the EVAP system solenoid/ valve if it is in that area
the frequency will be constant as the pump rpm is constant
the noise could be a venting noise from the EVAP in in that area
the distance of 15 km indicates that the problem is heat related as it take that long for something to over heat and cause the noise
you may get an indicator by running the fault code

Hi Tommy Parry, not totally sure on your problem but would suspect the heater core which is a radiator device inside the passenger compartment. The hot engine water is feed through the fire wall into the heater core when you select heat on the heater. either the heater core is leaking which is an expensive repair or the pipes maybe rubber pipes have a hole in them and checking them in the engine bay especially the hose clamps in the engine bay where the hoses are feed into the passenger compartment may be a starting point.

The first thing you do is have the engine control module scanned for fault codes. I also suggest you buy a can of spray throttle valve cleaner and clean the throttle valve and the idle speed control valve.

Hi,becouse the lot isnt working I would say at a gess mind you that it could be a brake in the wireing loom,if there is it could be where it goes from the body into the door,you will have to take the door card off and get a screwdriver with a light in it with a wire and crocadile clip,and see if the light lights up when you put it to something that should have power when switched on and working,try the window motor first,if it dosnt have power see if there is power at the switch on the wire side to the window motor the falt wont be in the when window switch is prest if there is power then like I sied before ther must be a brake in the wire loom,if there is no power try checking for power on the other side off the window switch then the falt wont be in the loom,hope this was some help,all the best

Check and see if rear brake lights are not working. If not working brake pedal switch id defective. Do Not go to dealer for repair. The will charge you over $100 for diagnostics and over $200 to replace switch. Go to reliable parts store purchase after market switch for between $16 and $35. Go to a local mechanic and have him put it in for you, labor will be about 1/2 hour or less. There is a small "door" located near the gear shift indicator on the console. It is about as large as a standard ball point pen. Using a ball point pen, insert it through the spring loaded door and gently pushing straight down while pressing on the brake pedal, you can now move gear shift lever out of part into reverse, neutral or drive. You will need to repeat this process until you replace the brake pedal switch.
