FUEL PRESSURE RELIEF

WARNING:Always relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.

Fuel system is under pressure. Relieve pressure before servicing fuel system. Fuel pressure may be relieved using one of 2 different methods.
One method is to disconnect fuel pump connector. Start engine and allow to run until it stops. Operate starter for 3 seconds to remove remaining fuel from fuel lines. Reconnect fuel pump once repair is complete.
The other method is to install Fuel Pressure Gauge (J-34730-1) on fuel pressure test port. When installing fuel pressure gauge, wrap shop towel

Its on the R/H side of dash near the computer-

Yes you do

You need this tool its either 5/16 or 3/8

Standard use is either clamp it around the hose or insert the tool into the connector and push both tool and hose towards each other usually you have to wiggle it a little bit it should pop loose fairly easily.

Just do below to remove/depressurize the fuel pressure to change out the fuel filter

One method is to disconnect fuel pump connector. Start engine and allow to run until it stops. Operate starter for 3 seconds to remove remaining fuel from fuel lines. Reconnect fuel pump once repair is complete.

I figure that in the very beginning -The fuel pump connector is on the back I have no exact location for you, also when you remove fuse no.6 and crank the engine a few times it will depressurize the system, of course its not gonna start you disable the fuel pump-
