Warm Engine

Fig. 19 Control Pressure Graph (Warm Engine):

1. Connect the vehicle harness connector to the control pressure regulator.
2. Activate the switch on the by-pass harness; after 5 minutes, the control pressure should range as shown in Fig. 19.
3. If these values are not obtained check the power at connector.
4. If there is current at the plug, replace the control pressure regulator.
5. If the rise in pressure occurs too rapidly, replace the control pressure regulator.
6. Shut off the fuel pumps.
