engine stopped going down the road
2006 MBZ E-350, 133,000 miles, never had a single problem and it just stops. The engine turns over, sounds like the fuel pumps are kicking in, the fuel pump relay clicks, I am guessing that it is a crankshaft sensor thinking that if it was a camshaft sensor, the engine would still run with one of them still working, but not very good. Two camshaft sensors, one crankshaft sensor, that is my belief. I am interested in opinions and where and how to replace it.
Thanks!

Get it checked with Mercedes Star diagnostic so you won't waste money on parts and labor you don't need.

Crankshaft Position Sensor. I carry a spare and the tools and the extra E8 Torx bolt for it just in case. It only took once on the side of the road to convince me. Makes me think I'm driving an old British MG.... I've posted on it. Search. FWIW and YMMV.

My Benz is stuck in a parking lot, and so taking it to do diagnostics won't work. Happy to hear that you carry one with you, I probably will from now on Did you replace yours from the top, or come in from the bottom of the car? Any pictures of exactly where it is. I looked to see it, but the firewall is so close to the back of the engine that I couldn't see it.

I am 99% sure it is the crankshaft sensor, and bought one for $40.00. it will be an easy thing to try first. Versus several hundred by the time I am done in towing, diagnostics, labor, and then probably $80 for the same part. If I wasn't 99% sure, I would have it towed home and tap into it anyway. Shops very rarely work on my vehicles because the computers tell them things are wrong that aren't 99% of the time. But thanks for the suggestion

Chiming with suspecting the CPS. Was it a hot day? When my CP's is failing it seems to correlate strongly to high ambient temps. Mileage sounds right too. Does the engine sound like it is gunning and gunning without turning over and then just gives up? My 2001 W210 and my 2003 W211 both had the same issue. The only bummer is you need to wait until the engine is cold before replacing or risk burning the hell out of your arm when doing the job. On the bright side it's a really easy replacement.

My son was driving it, said it started losing power about a block before, then just stopped. But interestingly enough, it turns over more rapidly than usual but doesn't actually start, so it is interesting you ask the question. I heard they go bad, but thought I might have gotten lucky. I heard the camshaft sensors go bad as well. But I figured that it would be very unlikely both camshaft sensors went bad at the same time, but one crank shaft sensor going bad (since there is only one) and the engine may not run.
99% sure after verifying the fuel pump is work. These cars have two fuel pumps, and so even if one wasn't working, I believe it would still at least run.
Thanks for the input!

I have a chart for the fuses, but not for the relays. Can anyone provide me with a chart that shows which relay does what? I am specifically trying to find the fuel pump relay being led to believe it is the lowest relay in the trunk on the drivers side where the fuse/relays are. But I see in other forums saying that isn't where it is without stating where it is.
Thanks!
Thanks!

Thank you, that was very helpful. You don't by any chance have the pin layout of the connector to the fuel pump do you. The one with 4 pins? I am sure two of the pins are for the float and then the other to power the pump, then ground. But don' t know which is which. The other wire I am sure runs the other pump. Also, I assume that if the other pump goes bad, the car will still run if you have plenty of gas in it. But is that true?

I could really use the pin layout for the connectors to the fuel pump on the driver's side. I replaced the relay, pump, fuse, but the pump is still not kicking on. So I want to test for voltage and possibly hot wire it to get it home. It is sitting in a parking lot.
I can probably guess by using my multi-meter, but if someone has the pin layout, it would be great
