02 S600 Problems
It will be crushed if I don't buy it, so I want to see if I can get it running..
The story:
128k miles, black on black.
Hooked up a battery and it cranks..
Sprayed some starting fluid into the intake and it sputters for a split second and then goes back to just cranking..
Fuel pump comes to mind, but I don't want to throw parts at it. Want to narrow it down before buying stuff.
I already checked both fuse boxes under the hood, fuses look good.
I understand that these cars can be a nightmare to diagnose, so I'll try my best to relay any information that is asked for.
Thanks in advance for the support
A check of codes would be a good idea (since the battery had been disconnected), but you need a good understanding of this complex machine, but you need a DAS MB diagnostic on it, not your regular OBDII.
good luck!

Any idea were I can start? I don't have access to the Star system for diagnosis, I can try to use the snap-on scanner we have. I'll be heading in to work in a few minutes and I'll be there for the day.
Could failed or failing coils cause it to not fire?

I tried to crank it earlier today with 3 jump boxes attached and the battery (which is low), and I would get labored cranking along with flashing dash lights...
My only thought is, if it sputtered the other day with the jump boxes attached and starting fluid why wouldn't it stay on??? Would a low battery really cause it to stall even after it began to start???
I really want to save this car from the crusher, but I cant afford to purchase another not running car. If I can get it started, I'll get it in a heart beat.
Too many projects right now

In the mean time, If I get a good battery and it still cranks with no start, any ideas on where to look next?
Thanks for the help guys
There's no use putting in a junkyard battery . W220 Mercedes requires a very strong battery to start it. Put in a strong one from one of your own cars or get a new one . You are just wasting time playing with weak batteries
Had you considered whether someone had put diesel into the tank?

I may just order the CPS and see how that goes, found them for $13 new oem quality (supposedly).. Would a faulty MAF sensor cause a no start?
How often do the coils and transformer go?
Thanks guys.
Coils you can get at most auto parts stores, transformer im not sure. Looks like ur gonna end up buying this car with all the parts youre buying!
The ECU, if fried, can only be replaced by dealer, as it is a "write once only" component married to the car. You need a DAS interrogation.
Forget your Snap-on, I believe it does not have the full multiplexer required, but anybody with a lap top and DAS can do it.
good luck!
