its known in Australia that sometimes its the valving in the shocker causing it to knock,get shock absorbers checked,it should be under new car warranty still unless youve exceeded the mileage,but they are known to have the odd faulty shock absorber
have you checked the switch at the top of the steering colum,that turns on and off the parker lights sometimes people touch it accidently and the lights stay on
no relay involved should find live wire behind head deck just get ur self a test light 12 bucks earth @ crimp end and needle point @ other with light up test the red or yellow cables with key off insure earth crimp is on chassis etc and push needle end on wires 1 should light up
Check the rear anti roll bar end links. This is a common item to fail as the originals were plastic !
If they are worn my advice is to replace them with some aluminum ones that come with nylon urethane bushes.
you should already have a wire shunt in the main harness for the tach. all you need is the sending unit and the gauge. the sending unit goes in a port on top of the transmission next to the engin bloc. the dealer ship will have the schematic for your specific vehicle and the right sending unit............please rate this
If it's a push button start that you're talking about, make sure your brake lights are coming on when it's acting up. Sometimes I've had intermittent brake on/off switches cause a no crank concern because the car doesn't know you're stepping on the brake pedal. Just have someone watch the brake lights if it acts up on you.
