The fuel pump relay is controlled from pin 51(A), which is grounded so that the relay pulls. When the ignition is switched "ON", the fuel pump relay
pulls for 1 second. This builds up pressure before preinjection, which occurs when the crankshaft begins to rotate.
When the crankshaft then rotates, relay 7 is pulled until the ignition leaves the ON position or the crankshaft stops rotating.
