How much pressure does the injector need to work properly? I know the fuel reg is set about 29 psi. |

The fuel pump shood turn off if the engine dies. That is why the ECU controls the ground to the fuel pump relay. It turns the fuel pump on at three times
1- upon initial key to on, for about 1.5 seconds 2 whenever the starter is engaged - key switch to start. 3- when the engine is exceeding X RPM's The design is for the fuel pump to shut off if the engine stops for some reason. Be careful here as an engine problem due to leaking fuel lines will cause the engine to run poorly or stop. You don't want the fuel pump running if there is a leak. Tom |
