Fuel Pressure Regulator Test

Reconnect coil connector at coil and inertia switch or fuel pump relay. Reconnect injectors properly. Connect pressure gauge. Start engine and run at idle. Observe pressure reading. Pressure reading should be 35-45 psi. If not to specification, check fuel lines for kinks and perform FUEL PUMP  tests.
