My 190e auto has suddenly developed a fuel pump problem, non-starting, with no sound of the pump whining when the ignition key is turned on.
Reading previous posts on the subject, I removed the pump relay and substituted a shorting link across the 87/30 pins. Still nothing.
A check on the voltage at the pump terminals, with one wire removed and the link still in place, shows a voltage of about 1.5 volts across the supply.
The resistance measured across the pump is about 2 ohms, which sounds ok.
I presume from this that there is a partial short circuit somewhere in the wire between the relay socket and the pump terminals.
(We're on a farm and predation by rats is not unknown !)
Can anyone give me any guidance on the route the loom takes, and where there might be any access to it. I can see that it disappears into the bodywork close to the pump, so I'm hoping that I can get to it from inside the car.
Many thanks
John
