relay holder
1 - fuel pump relay
2 - heater fan relay
3 - fog lamp relay
4 - horn relay
The fuel pump relay is located on the relay holder behind the fuse box. It supplies the fuel pump with electricity. By means of a safety switch, it cuts off the fuel supply when no rev pulses are generated with the ignition on, for example when the engine has stopped.
If, to test the injection system, it is necessary to turn on the fuel pump with the engine stopped, disconnect the relay and connect terminals 30 and 87b with a short auxiliary cable. The wire diameter should be 1.5 mm.
