MBWorld.org Forums - E320 died at a stoplight and doesn't start anymore

Recently got a W210 E320 in very nice condition from a old man that had driven it for 15 years, classic story. Few days ago, it was a very cold morning ( -15C), it started up and i drove it for like 20 minutes, before it starting to sputter and dying right a stop light and wouldnt start back up. First i thought that there was no fuel, or it had sucked up an air bubble. Ran to the gas station, put in a few liters of diesel, still nothing. Ended up getting towed to my workshop. Then i changed the fuel filter, as it may have been frozen, still no start. then i checked if the low pressure pump is even creating a vacuum, and i dont know if it should be like that, but its very weak. So waiting on a LPFP right now to be delivered, hoping that thats it. Any further suggestions? thanks
