fuel pressure question

[psi4mymitsu]

Heres the question Im running a walboro 255,Aeromotive filter,Aeromotive fpr set at 43 with vac line disconnected when I have the key on engine off no fuel pump buzz and of course no fuel pressure.But then I turn the car on fuel pressure right away fuel pump works right away and the car runs fine even boosting 18 pounds.When I looked this up in older forums I heard other people having the same problem but they always talked about having driveability issues and long start up issues.That confused me cause the car runs great and starts like a champ.Im not really worried cause the car is running fine but Im still curious.Oh yeah the car is a 95 GSX.

The ECU will not turn on the fuel pump relay until it sees CAS activity. However, you can connect the fuel pump diagnostics terminal (the black one) on the firewall to the postive post on the battery to turn on the pump.
