    Hi I wonder if anyone can give me some advice on what seems a common problem ? I have a 1.6 1989 Gti which refuses to start intermittently .I have changed the Tachymetric relay for another .Admittedly second hand .But it still does it .I checked the voltages on the relay when it refused to start and got the following Pin 30 = 12v , Pin 50 = 9.5 v , Pin 15 = 12v , Pin 1= 12v and Pins 87B and 87 = o.0 v .Pin 31 Earth = 0.0 v ( which is of course obvious ) . As far as I know Pins 87 & 87B are the contacts to convey power to the Fuel pump and Injectors .Is the voltage on Pin 50 ( the one from the Starter Solenoid ) enough ? Or does it have to be a very close 12 v to operate the relay .Any idea what I should be looking for ? Thanks in advance .
