08 S550 Front end crash. No start after repairs.
I bought a black on black 2008 S550 4 matic 90,000km with a clean title.
Crash hit up high and pushed the radiator up against the engine. Engine and transmission mounts broke. Oil pan shattered.
I removed the engine and transmission and looked for any other damage and found nothing. Engine turns by hand.
I put everything in except the exhaust and front end and it will not start. No crank. Tried swapping modules and fuses from another s550 parts car and nothing. I think I hear the fuel pump going and fuel came out when disconnecting the fuel line.
Any ideas?

Ah, there's the link I was looking for. https://batteryuniversity.com/learn/...tate_of_charge -- at 11.6 your battery is pretty much fully discharged. It should show at least 12.5 or higher if it's a good battery and is charged. I'd say throw a battery charger on it for a day or two, try to crank it, and see what the voltage is afterward. Even a bad battery will often show 12.5 to 12.7 after charging, until the first time it sees any kind of load.

The voltage doesn’t change at all after charging.

Either your meter is faulty or those batteries are bad. You simply cannot have 11.6 V on a good battery after a full charge.
(Or you have a HUGE load present in the car, but it had to be so big that I cannot belive that is the case).

What kind of load could it be?

Just in case, forget the scanner and mesure the voltage with a volt-meter at hte battery posts. I insist a battery cannot have 11.6 V after a full charge.
If you had a load able to make a good battery go to 11.6 I can assure you that you would notice the spark when connecting it, so we can forget about that.

What he said. A $5 (or freebie) Harbor Freight multimeter on the 20V scale will tell you the state of your battery with far more accuracy and reliability than almost any on-board or plug-in monitor.

Have you gone through and checked all the fuses and pre fuses, if it was hit high it may have blown some fuses in the system, for it to break mounts etc it would have been a decent impact.

Swapped the module beside the starter battery and above the rear trunk battery. Nothing. Swapped the modules from my project into my daily and they worked perfectly.
Ive seen online people get their benzs reset after a crash with a high end scan tool. They have the same issue. Reading no gas, all interior functions work but nothing happens when you try to startup. So maybe that’s it ?

First off, if you haven't done a Star Diagnostic to rule certain things out, you are just running around in circles. Secondly, if you car has a battery in front and back, both will need to be sufficiently charged to rule certain things out.

Hey a little update here. So I’ve got two new batteries plus a new starter. Starter was tested and was actually bad. I got it running using a screw driver and jumping the two connections on the starter. Still won’t start by the key. Yes I know I should have somebody skilled look at it. I’ll get that done here soon.

Within DAS, there is a function entitled “engine restart after crash “ I have not used it, but it leads me to believe there is a procedure that the electronic managers on board need in order to say it’s ok for the engine to startup (or not). You should consider buying your own DAS with the project car issues as well as your other MBs that will develop them as time goes by, likely pay for itself in short order. Good luck and keep us posted.

Right now I’m trying to fix an issue with the interior climate controls not functioning while blower won’t shut off and the engine fan won’t shut off. No matter what I press it stays the same.

I did some resetting / relearn of the transmission on my $300 scan tool and the car started right up and runs really smooth. This was about a month and a half ago.
