2001 ML55 AMG No Crank, No Start - Rookie Mistake

Hi everyone, I'm new to the BenzWorld forum but have a MBWorld account and still have a Club202 account! I have noticed that the BenzWorld forum for the W163 gets pretty good amount of traffic and responses from Witek, 43spd, mattml430, noodles, etc, etc. You guys are awesome. Anyhow a few months ago I purchased a 01 ML55 AMG w/ 89,000 miles on it that needed some pretty significant TLC. Over the past few months I've been working on getting it up to spec. Recently though, I believe I may have caused some significant electrical damage that is now causing the car to intermittently start.

Here's what happened...........so the previous owner had Best Buy install a new headunit that had Sirius, bluetooth, etc. So since I have the car just about all in pieces since I'm doing a full overhaul of the system, redoing the carpets, leatherique on the seats, etc, etc I decided to check to see if the original factory Alpine unit still worked so I plugged it into the factory harness (with the battery still on the charger and at 100% charge.....also without the keys in the ignition) and out of the corner of my eye I see the dash lights flash for a split second and next thing I know the car won't start anymore.

Here's the catch though, now if I leave the car alone for a few days it'll start right up with no issues but then after turning it off and trying to restart it.......no dice. Additionally, upon plugging in the old headunit and aftermarket headunit, there's no power to them anymore.

To add more context, one thing I didn't even pick up on (which I should have) is that the factory harness was tapped into at the pink (ignition/switched) wire (I believe?) and the brown (ground) wire for the Sirius setup that was installed with the newer headunit. Could this have caused this issue or did I totally goof by plugging in the factory headunit with the car on a battery charger?

I've scanned with STAR and get a bunch of CAN bus errors (obviously) but DAS still recognizes all of the 3 keys as noted by the light blinking in position 1. I can post the codes when I get a chance, but I'm not seeing any fuses blown or anything like that. Nor am I getting a 'start error' message on the cluster.

Anyone have any insight here? I would really appreciate it. I would love to get this beast finalized and back on the road!

I would start by making sure no earths have been disconnected while in there or they maybe on a loose bolt and giving intermittent connection.

Your symptoms are somewhat baffling, but I would look at any/all connections made when the new head unit was installed.

I know I feel like this is such a bizarre occurrence but ok I will check all the earths to see if there is anything loose.............is it also possible that an occurrence like mine could burn out the ignition switch?

Sorry, but why is there power to anything if the battery is on the charger? You disconnected the battery from the car, right?

I think this was my first mistake here......................no the battery was still connected to the car when the charger was on it

What is the resting voltage of your battery? In my experience over-voltage will cause as many CanBus issues as under. I know these vehicles are very sensitive to voltages outside of normal tolerances.

I see we live close to each other and I'd be willing to come take a look with you if you can't figure it out. I'm not a master mechanic, but I do have 30 years of old man experience and self service both my Mercedes.

Good luck with it and let us know how it goes.

Probably a non-fatal error if you can still start it, but cars of this era are full of fryable modules. (Maybe you only killed the headunit circuit.)

What happens when you attempt to restart immediately after engine stop? No crank at all? Or long-crank-no-start?

What happens later that day or the next day when you try again? How many days did it take last time?

I actually haven’t checked that....I’ll check and report back here

But if you’d be willing to swing by that’d be awesome! I’d even pay!

I am going to look around some more tonight and tomorrow to see if I can find anything obvious. I’ll let you know.

Ok ok gotcha so you’re thinking that a shorted headunit circuit could potentially be related to the intermittent no start no crank?

It’s weird because some days the car will fire right up and then be put through a series of shut downs and restarts as if there’s no issue and then other days it’ll start up and then if shut down it won’t start again for another 3-4 days only if left completely untouched.

I’m not sure if this is even relevant but right now I have a few body panels (hood, bumpers, fenders, LF door) off the car since I’m getting them resprayed. Doubtful that they’re related to this?
