New '72 280SEL, couple questions - Benzworld.org

Hey everyone! Well, I've ran the course of my "Jaguar phase" and have recently jumped back into the MB world, and it's looking more and more "headfirst" as I research!
As the title suggests, I recently came across a 1972 280SEL in really good shape overall. I am having a little trouble though, finding some sort of service manual for the vehicle, any suggestions?
Everything was running perfectly when I got home, but while moving it in the driveway I applied the brake and apparently "something" blew. Car just quit, and wouldn't start again. My first thought was that some relay/fuse blew, and since I am still getting spark, I believe that is the issue. I have found that there is a fuel pump relay, but I cannot find the location. All the fuses in the cabin are good, but none of them seem relative.
Without a manual, I'm not sure where I should check for fuel delivery.
Any information would be greatly appreciated as I have not been able to find anything specific in the forums. Thanks in advance!

If you search the forum for "Fuel Pump Relay" you'll find many usefull threads about this same issue, including this one. Click here

I found a Chilton on ebay for about $10 that is a good basic repair guide which includes all the wiring diagrams. Try rolling all your fuses to clean any corrosion or replace them with newer copper style. I believe fuse 4 powers the fuel pump relay. I'll have to check for certain when i get home from work.
