Barn Find 500SL Journey

Hey everyone, I just got myself a barn find 1992 500SL with roughly 48k miles that has been sitting for 8 years. I plan to make it my daily once I can get it running. So far I've replaced the sparkplugs, air filters, oil filter, and oil. It starts, briefly. It then dies after a couple seconds of running extremely rough. I've traced it down to a fuel issue, probably fuel filter or pumps if I had to guess. Anyways, that isn't the point of this. I'm new to the SL's, and was wondering what I should look out for on this thing to make it as reliable of a daily as I can. From what I saw during my brief moments of a running engine. ABS and ASR light are on, so I'm looking for tips on how to trace down possible causes if they persist. Thanks guys, and I will update this thread with my progress on getting it running. I assume I will need some help.

Instead of just guessing, for starters read your diagnostic trouble codes (DTCs). Also, check the distributor caps and wires if not already done.
