SL/R129: SL600 Engine Failed to start
I have a "No kick-down output signal error" reads on my diagnostic machine - which I conclude to replace both the kick down switch and the kick down relay including the inter-connector (ferrule) for the transmission wiring. While waiting for the parts to arrive I put the car in my garage and did not start the car for 2 month - until last night and it failed to start!!!
I have checked;
1) There is fuel in the tank
2) there is sparks at all spark pugs.
3) No error in registered in my diagnostic machine.
Please advise. thank you
