Is the main supply connection ok? Check polarity!
Does DP+ (VCS ON) lie on clamp 6 of the plug with 6 pins?

8.4.2 Fuel solenoid valve
For start problems the possibility of an error exists with the solenoid for engine stop or fuel solenoid valve, which
both effect affect simultaneous on the fuel system.
The fuel solenoid valve is located in front of the injection pump. It opens automatically, if the „START“-button is
pressed on the remote control panel. The solenoid valve is CLOSED when the generator main power is switched
„OFF“. For this reason, it requires a few seconds before the motor comes to a full halt.
If the generator fails to start, runs rough, does not reach the proper RPM, or does not stop properly, the first item to
suspect in most cases is the fuel solenoid valve and should be inspected first.
A check of the fuel solenoid valve by removing the plug from the fuel solenoid valve for a short period whilst in
operation (first remove the small retention screw) and replace it immediately. The motor should „react immediately“
by revving high.If the motor does not react sharply to the re-connection of the solenoid wire, it is a sign that the
solenoid
