Fuel Pressure: Notes

WARNING: Always relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT  allow fuel to contact engine or electrical components. If connecting fuel pressure gauge to fuel system without using a "T" connector, DO NOT  operate fuel pump for more than a few seconds. Operating fuel pump for longer than a few seconds under this condition damages fuel pump.

Basic diagnosis of fuel system should begin by determining fuel system pressure. If fuel pump is inoperative, see appropriate FUEL PUMP CIRCUIT TEST chart under FUEL PUMP CIRCUIT TESTS  .
