W140 - cannot start -- Ignition Control Box
This is a very sad afternoon.
I have a 1994 W140 S500 which has 100K miles on it.
The car drives exceptionally well until last night. The car starts and runs a bit rough and it stalls after 10 seconds or so. I tried a few times, and still no luck. I let it rest for a few hours and came back to find the engine will turn but will not start anymore.
I immediate reaction is fuel or fuel pump etc problem. I have got the car toll back to the dealer and have it checked.
I received a call from the service manager to say that the "Ignition Control Box" was blown. To replace it is $$$$$$.
I asked what is that box doing and why it is so expensive??? I cannot get a good answer!!!
Can anyone give me some comforting explaination for me???
