Hello, new to diesel benz, not diesels, I have several cummins, & a couple ford (internationals) never had a benz & got this one pretty reasonable I thought I might drive it back & forth to work if I can get it to run good. If not I will probably just resell it.

Just bought a 1983 300sd, it has about 350k on it has a terible exhaust leak & misses on 2 cylinders, I bought it this weekend, I cracked the injector lines open today & makes no difference on 1 & 2. there is little pressure at those 2 lines, I will check the compression at first chance to see the mechanical condition. Is there any tests for the pump without taking it off & bench tested? It came with the parts to fix the exhaust. There are some used pumps on ebay cheap, I may get one of those & just try it, probably cheaper than a bench test!!
Thanks
