Plymouth Fuel system Hose And Fuel Pump assembly:---

Start at the canister under the hood and see that the vapor hose to the fuel tank is clear. The check valve is at the tank, you can try the "jiggle" of it, but you will want to see if the fuel will go into the tank with it unplugged, temporarily, as with the front part as well.

Relieving Fuel System Pressure

Disconnect the negative battery cable.

Remove the fuel tank filler cap to release the pressure in the fuel tank.

Remove the cap from the fuel pressure test port on the fuel rail.

Place the open end of Fuel Pressure Release Hose tool C-4799-1, into an approved gasoline container. Place a shop towel under the test port.

Connect the other end of the hose onto the fuel pressure test port to relieve the system pressure.

After the fuel pressure has been released, remove the hose from the test port and install the cap.

When repairs are completed, connect the negative battery cable.

Plymouth fuel filter replace:---

The fuel filter mounts to the top of the fuel tank. The inlet and outlet tubes are permanently attached to the filter

REMOVAL

Perform fuel system pressure release. (with the engine running, remove the fuel pump relay or fuse, wait for the vehicle to stall)

Disconnect quick-connect fittings from fuel pump module and chassis fuel supply tube.

Remove filter retaining screw

To remove the fuel filter, it may me necessary to lower the fuel tank about 3 inches.

INSTALLATION

Install fuel filter to tank.

The fuel supply (to filter) tube, return tube (to pump module) and fuel supply (to chassis fuel line) are permanently attached the fuel filter.

The ends of the fuel supply and return tubes have different size quick-connect fittings.

Apply a light coating of clean 30 weight engine oil to the fuel filter nipples.

Install fuel tubes.

The Fuel pump relay:

The relay is located on the left fender under the hood.

To Test the Fuel Pump relay:---

Remove relay before testing.

Using an ohmmeter, perform a resistance test between terminals 85 and 86. Resistance value (ohms) should be 75 ±5 ohms for resistor equipped relays.

Connect the ohmmeter between terminals number 87A and 30. Continuity should be present at this time.

Connect the ohmmeter between terminals number 87 and 30. Continuity should not be present at this time.

Use a set of jumper wires (16 gauge or smaller). Connect one jumper wire between terminal number 85 (on the relay) to the ground side (-) of a 12 Volt power source.

Attach the other jumper wire to the positive side (+) of a 12V power source. Do not connect this jumper wire to relay at this time.

Caution: Do not allow the ohmmeter to contact terminals 85 or 86 during these tests. Damage to ohmmeter may result.

Attach the other jumper wire (12V +) to terminal number 86. This will activate the relay. Continuity should now be present between terminals number 87 and 30. Continuity should not be present between terminals number 87A and 30.

Disconnect jumper wires from relay and 12 Volt power source.

If continuity or resistance tests did not pass, replace relay. If tests passed, refer to Wiring Diagrams for fuel system wiring diagrams.

You can run 12 volts to the pump to test it. You also do realize you only get voltage to the pump for a couple seconds when turning the key on correct? Then you get voltage again when cranking.

If you have voltage to the pump and no fuel pressure then yes the pump is bad or there is no fuel in the tank.

HOWTO REPLACE Throttle Body

Disconnect the negative battery cable.
Remove the air inlet-to-throttle body hose clamp.
Remove the 2 mounting screws and air inlet resonator.

Remove the throttle body assembly and mounting gasket.

To install:

Position the throttle body, along with a new mounting gasket, onto the intake manifold.
Install the mounting nuts and tighten to 18 ft. lbs. (25 Nm).
Connect the vacuum hoses to the throttle bod
Attach the IAC motor and TPS electrical connections to the throttle body.
Connect the throttle and speed control (if equipped) cables.
Install the air cleaner/inlet resonator assembly.
Connect the negative battery cable.
