[T3] Question re F.I. fuel pump cutoff

[Robert Bills]

 The fuel injection fuel pump for my '73 Squareback is supposed to run 1-2 sec. when the ignition switch is turned to the "on" position, then stop until the engine fires.  Mine did, but now runs all the time when the ignition is turned to "on."  Since the cutoff is a safety feature to prevent the pump from running when the engine quits, thereby preventing a gasoline catastophe, I need it to work properly.


My reading of various fuel injection manuals for the Bosch D-Jet suggests, but does not clearly state, that it is the fuel pump relay that controls this function.  Is this correct?  (makes sense to me, because this is an open loop system.)  If not, what does?
