Fuel Pump Relay Control
WARNING: This page is about a different car, the 1989 BMW 325is, 1989 BMW 325iX, and 1989 BMW 325i. However, it is still accessible from the selected car via links, so may be relevant.
The test terminal is 3 and ground. Bridge terminal 36 and 2 with fused jumper wire is the test condition. Fuel pumps should run (audibly) when terminal 3 is touched to ground is the correct test value.
