long trip and a stop at MB dealer just wasn't rewarding. The dealer ship reset the fuel and it ran well for ten miles,then began to run rough and stall,when we spent some time on the side of the road it restarted long enough to get us home.Now it will start four ten or fifteen seconds,and stall then you can crank on it all you wish,But it isn't going to start,Any thoughts?
Im thinking in electrical problems.

How is the fuel filter/accumulaor/pump? I would guess one of those will cause your problem but not %100. When you turn the key all the way before you start the car, do you hear a faint "hissing noise"? If you do not then check your fuel pump or all relays and fuses

you need
1. fuel
2. spark
3. air

check the basics.... if one is missing, concentrate on that system.

The car is a 1990 420sel and yes the relay was the fourth item r/r-d, j-n-t

It would seem a lot of fuel delivery items have been changed.

If the car sat idle for a long time, I suppose I'd suspect the injectors.

Personally, I'd find a legitimate independent tech and explain what's been done and pay him an hrs. labor or so for some diagnostic work.

My 2 cents.
