I couldn't believe it, my wife couldn't get our 1998 ML320 started and had it towed home. I try and it starts right up! The difference is the key. I used the spare key and she used her everyday key. I tried her key and it wouldn't work, got the same thing. She wanted to throw something at me!

Here's the symtoms:

1. Insert key, turn and start in one smooth motion -> car starts -> runs for two seconds -> stalls out -> repeat and exactly the same thing happens, over and over.

2. Insert key, turn to starting position, pause two seconds (allow all dashboard idiot lights to come on) -> turn to start and nothing happens. No starter, nothing, dead quiet. Repeat and exactly the same thing happens.

The spare key starts it in any condition. Do I have a worn out key, or ignition switch, or ????? Thanks in advance for any help you can offer.

Don
