first time ever doing this so bear with please. I bought a 1981 Mercedes 380 sel it has been sitting awhile. I have replaced the fuel pump and filter and flushed tank. I replaced the relay still no fuel to the engine. I jumpered around the relay and I get fuel. Not sure what is holding me out. I read some where that it could be the fuel cut off switch but can't find it to check any and all ideas with locating it or other ideas why this dang thing won't start would be helpful. I have sunk a ton of money trying to get this thing running. Hard to do on ssi. Thanks for any and all help Sno.
