A automatic ECU won't start at a manual car because it won't get the signal, that the transmission is in P or N. So if you buyed the new ECU, Skreem and Keys from a car with automatic transmission (what is very likely because it gives not many crossfire with manual transmission) you will have the same issue as you have now. The starter will do nothing.
But I think I can help you, I'm from Germany and can test your skreem and ecu. I could also make you a new key or you can buy my Skreemulator.
If you are interested please contact me over DM.

 

Many Thanks
I see you post. If new ECU won't work, I will send you a message.
Thanks
Nicolas

 

Would a SLK320 have the same ECU ? is essentially the same car and may be more in Europe with manual transmissions.

BTW my first 07 Coupe had a six-speed, saw somewhere that about 1/3 had the manual. Traffic has gotten so bad here I decided to go with an automagic.

 

Yes you can use the Skreem+ECU+Keys from a SLK320 R170.

 

That is the "Key In" buzzer wiring, it will not stop the car from starting but I find it odd you have no such wires.

 

When you press the pulse relay, the starter will engage no matter what else is wrong. But the ECU will not fire plugs unless all is OK. This test just proves that your battery and starter are good.

 

Is this eventualy only for automatic so that you can't get the key out if you don't have the shifting lever on P?
On european Crossfires there is also no key in buzzer.

 

No there is a cable that attaches to the ignition cylinder, (not electrical but mechanical) that comes up from the SLA in the autos for that function.

Here you go, from the "Sticky Key" document that Bob McCubbin wrote:

 

Hello
Bad new, parcel delivery damage. As nothing visible outside the box, I see when package open ... I think all $$ for me.



Do you think PIC could be change ?

Nicolas

 

What the hell does the parcel company with it? It needs a massive load to make a damage like this, is he driving with his truck over the parcel?
Of course you can try to change the pic but I think you have to solder it out from a other ECU and than is always the risk, that the PCB is damaged also.

 

Nothing visible outside the box means it was probably in that condition when shipped.

 

Thanks for your answer.
Crazy UPS ... seller send me picture before sending, no problem ...
I've order news ECU and tool for cloning.
I will try to find new pic in the same time.
I will let you know next step ...
Regards
Nicolas

 

News on my problem.
If could help me, or help somebody later.
I buy a Ktag chinese clone. Around 70€.
With this tool, I could save all ECU information of the break SLK ECU

In same time I do a backup of the ECU of the car. Looking the EEprom file, I notice that ECU was not the original one (ML 3.7 auto from VIN, don't know if map and
Flash are correct or not) => best I think is to use SLK ECU backup.
With SLK spare part, no start, but Fan not go to his maximum speed.
At this time, I think just need to change gear box setting.
I could share the SLKR170 3.2 ECU backup if somebody need ?
I will let you know next results
Have a nice day
Nicolas

 

News from Nicolas
Great thanks to nemiro and viper-666 helps.
Done :
* Immo of the SLK works :


* Seems the ECU don't have the information when I'm pressing clutch pedal. Keep inactive, whatever I press the pedal :

* Control Clutch pedal sensor + wiring to ECU :

Pin 4 of the ECU to the mass. Open when we press the pedal = OK
* Viper-666 give me EEprom file from an Mecanich gear box (with my key): no change. Setting must be saved in the Flash or other ... Many thanks to him
* Nemiro confirm my last problem could only come from gear setting. Thanks to him
As I don't have MB Star, i decide to confirm to try to start with pulse relay :
I push the relay of the pulse modul.
It's start. As Nemiro said, I need to configure my gear setting to solve No start.
In the same time, acceleration was not good. Few minutes ago, go down, and I've got a Throttle error (P202E = P0120 ?).
I will have a look on the Throttle end of this week... the car don't turn since 1 year and a half ..

Lot of works on this car ... but good news, I learn lot of things on this car.

Thanks to all

Nicolas

 

PM me.

 

"Throttle error (P202E = P0120 ?)" Just had an intermittent throttle and was a bad sensor in the gas pedal. I bought one on eBay and works fine. I had a P0122.

 

Thanks to all for you help.
With all of your help, I could solved mine problem.
Special Thank to Viper666 and Nemiro who help me to go over last step (go from auto gear box ECU to manual).
I will update my first message in order to list all test performed.
Thanks again
Nicolas

 

does rubber banding a relay cause any damage. for example, is a relay activated for a short time or does it remain activated till the car power is turned off. More specifically if I do that to the fuel pump relay will I have a problem?

 

Rubber banding the fuel pump relay is a way to get yourself home, but you'd better not leave it like that. That relay is supplied battery power, which means the pump runs forever, draining your battery (which is no big deal).

But what IS a big deal, is doing so keeps the ECU from disabling the fuel pump at times that it SHOULD be disabled, like when you try to start the car but it does not start - or in an accident, when you want the pump to stop running in cases where a fuel line is broken - the last thing you need, is 58PSI of gasoline spraying onto who-knows-what in an accident scene.

The rubber band is a test, a quick fix to get home, but that's all it is.

 

You could put a rubber on the two who run together.
For the fuel pump, you could push it with a wooden match 5 to 10 sec

(video is for pulse, but relay same)
Best way for me is to open RCM, test relay with 12V power supply
