Hi Forum Members.
My name is Keith and I am a new member, and currently live near Alicante in Spain.
I own a 1975 Series 3 with a 2.5 Diesel engine. Over the last 6 months I have been undertaking a complete restoration of the the car in the sun.
Having completed all bodywork and running gear etc, I am now working on the engine, the engine had been running very well although a bit of a pig to start sometimes.
I have changed the glow plugs to the new 12v ones and done modifications to the wiring setup and these heat up really quickly now.
I thought I would change the fuel filter as it looked quite old, having done this I now cannot start the beast although I have bled the fuel lines, I still seem to be getting a lot of air in the system and after various checks I don't appear to be getting fuel up to the injectors.
I have checked fuel cut off solenoid and this is working as far as I can make out (Clicking on key turn). When cranking the engine the voltage on the solenoid does drop to around 9.5 volts. Question - could this be partially closing thus restricting fuel flow to the pump.
I have checked all connections in the pipework and cannot find any leaks where air can pull back in. Question- Is it possible that the lift pump is faulty and fuel leaking back across the valves.
I would welcome any suggestions, or similar problems others may have experienced.
Hopefully speak again soom
Keith. (Keiths Landy)
