My wife had a 98 ml320 and and we dont have any major problem since we bought it. It was just yesterday that it suddenly stop and wont start, first I thought that she run out of gas because we had the fuel gauge problem for a long time but it was not. I towed the truck to the garage where I work for and tried to start it, it will start for a second or two and then dies, the engine sounds well, It seems like someone is turning off the key. Since I had the fuel gauge problem, I decided to change the fuel pump and I thought it might also be the cause. After replacing the pump, I got the gauge working but still have the engine problem. It looks like electrical problem but I dont know where to start, Im not so familiar with the Ml320 problems.
Any input will help thanks..

Try using a different key to start it. If that doesn't work, it could very well be a DAS problem.

It did start with my duplicate key, Thank you very very very much for your help

Yeah, happened to me too, 100 mile from home on vacation w/o second key. Towed to dealer who flew in a new key an programmed it. Sometimes the keys just quit communicating with the interlock system. I always take a second key when going out of town now.
