Morning All,
Took possession of a 1985 R107 SL280 in need of medium restoration. My first project!
The car was sold as a non runner with a possible faulty fuel pump being the possible reason however i have run a direct line to the fuel pump terminals and can hear it running.
As the car had been standing for approx 12 months i decided to drain the fuel tank, the petrol was brown in colour? I determined that the fuel pump relay had power from the battery and so assumed that the fuel pump relay is not doing its job. Cost to replace from Mercedes is £60, can i source cheaper?
Ok, so desperate to hear the engine i tried to fire her up by connecting the fuel pump directly to the battery however she turns but won't fire up. I pulled a spark plug and i am getting a spark (plugs are sooty) but it didnt smell of fuel so i assume that fuel isn't being delivered as i can't bypass the relay in this way or that i have caused an air lock in the fuel pipes by draining the fuel?
Any ideas greatly appreciated!
