First I would like to thank everyone for helping me on the 240D. Its running so good the wife wanted one !! With my guidance based entirely on what I have learned from this forum she purchased her first Mercedes. THANKS !

She bought an 81 300SD 214,000 miles. Meticulous log book on fuel mileage since 03 averaged 22 mpg continuously . Oil change Door stickers stacked 1/8 inch thick 3000 mile intervals. Tire rotation sticker on the windshield with brand new Khumos. It had it all including a new power steering pump starter and battery.

Now for the bad this is where the help is needed. The car will not start . When I went to check on it everything related to fuel is leaking. The old couple who owned it parked it in 07. The guy I bought it from got it running drove it home drove the family around that day then shut it off for the night and could never get it to restart. The engine turned over but wouldnt fire. Until last night.

I checked the primer there was no resistance. Kept this up until she pressurized. the glow light came on went off cranked an it fired. Oil pressure went up to 3 she stumbled shook then started . No pedal no power but it started getting better smoothed out right above idle. The guy is amazed by this time. Then we tried again you hear a clunking screeching noise (internal not the belts) coming from around the injection pump area. Try it several more times sometimes smooth other times that noise comes back it never stayed running.

I plan on fixing the fuel leaks replacing the primer pump adjusting the valves . Before trying to start it I was looking for some opinions on what to possibly check for the noise. I would hate to get in a hurry and destroy something if it can be avoided.

Any help is more than appreciated. Thanks in advance !!
