2000 S500 no turnover, keys turn

I have a 00 S500 at my shop when you turn the key on everything lights up normal but car will not start after turning the key. Check all visible fuses & square relays in left and right engine compartment and all fuses under rear seat. Disconnected and tried with new battery. Tried using both keys with same symptoms. Carsoft cleared codes in all modules. Engine ECU reports cannot communicate with EGS. EGS module reports a half dozen falts: disturbed communication to engine ECU, non-communication, and implausible values for engine rmp sensor. Also live data shows a constant and correct shifter position gear, but shows a gear value for the actual gear and target gear that occasionally flickers if you watch it close. The transmission connector has been replaced with a new one, and there was not any fluid in the wiring harnes during the change of the connector. The car can be cranked by bridging the starter with they key in position and starts and runs fine, but is in limp-home mode. Three SAM modules report no faults.

I know there is a 4th fuse box in the trunk, but does this have anything to do with starting?

Any help is appreciated.

Car will not start with either key.

Does this car have K40? If so where is the location?

Is there a box that controls CAN MOST or D2B comm between the engine ECU and the EGS ECU?

Thanks

Look like your EIS is toasted

Can you elaborate?

Can you elaborate? They keys turn fine & the dash lights up fine. No "Start error" message. How do you fix this?

How much charge is in your battery?

Even if you can turn it on, if it won't start, the standard route to take is check the battery, starter, fuel pump, alternator in that order. (maybe fuel pump and alternator can be switched)

Please complete your profile with model/year/location as this often helps.

You say that your starter is cranking. If so can you hear the fuel pump running? The Starter relay is K40/7 relay L, located in the engine right fuse/relay box. The fuel pump relay is relay T, located in the trunk fuse/relay box.

The fusebox details for W215 are on the thread below. It is also valid for your W220.

http://www.benzworld.org/forums/w220...lay-chart.html.

There are several things that can inhibit starting, however if the key will turn fully, you must have satisfied the DAS (drive authorization system).

I would take out a sparkplug to see if is wet. That would confirm that fuel is getting through.

As I said, the starter can be bridged & the car starts, runs, & revs fine. The car can be driven, but the trans is in electrical limp home mode. I'm thinking that maybe since Carsoft MB shows the target & current gear flickering that maybe EGS isn't saying that the car is in park?

Other possibilities are a blown fuse, bad relay, can issues, or EIS issues.

* key turns fully
* fuel pump & spark are working
* bridging starter with key in position 2 cranks & runs
* Carsoft MB shows engine cannot see EGS
* Carsoft MB shows many EGS comm errors & sensor errors

car just doesn't start normally

This model will have the 722.6 transmission - right?

L-H mode is set from the EGS (N15/3) and should put a fault code in memory. You can only move in 2nd and R gears. What does the code say?

The Electronic Control Unit (Y3/6) within the transmission does contain a Starter lockout contact (Y3/6 s1) which recognize shift lever positions P & N.

Have you examined the EGS (N15/3) in the passenger footwell for signs of ATF wicking from the transmission connector? This known problem does produce transmission faults - but not start problems.

One more thing that can affect starting. Faulty brake light switch (under the pedal?) Two sets of contacts - 1 n/o for the lights, 1 n/c for start permission.
