The 190 relais set is mounted in the fuse box on the left side of the
motor compartment. The fule pump relais is the second largest nr 155 in

Attention!!
The Fuel Pump Relay 8the one numbered 155 in the figure) in not in the
fuse box, but in the opposite side of the motor compartment, behind the
battery. There, you will find a plastic panel that separates the battery
from the relay zone. Relays that lies here are the ASD Relay, the Fuel
Pump and the Klima relay. All they receive some signal from some sensors
from many parts of motor.
You can verify if the problem is the fuel pump relay, attaching a led
diode between the Pin 87 of the relay and the ground. You need to put a
820 ohm resistence among the catode and the ground.
If the led turns off while the motor stops, 95% the problem depends from
the relay.
Think that the relay receive also a RPM signal that is divided between
fuel pump Relay (TD pin), the ASD relay and the tachimeter. If this
signal is abnormal the relay enter in 'protection mode' and the engine
stops.

Hope this can help
