REMOVAL & INSTALLATION
(see Figures 1 and 2)

CAUTION The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

1. Relieve the fuel system pressure using the recommended procedure.
2. Disconnect the negative battery cable.
3. Drain the fuel tank, then remove the fuel tank from the vehicle.
4. While holding the modular fuel sender assembly down, remove the snap-ring from the designated slots located on the retainer.

WARNING The modular fuel sender assembly may spring up from its position. When removing the modular fuel sender from the tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float.

1. Remove the external fuel strainer.
2. Detach the Connector Position Assurance (CPA) piece from the electrical connector and detach the fuel pump electrical connector.
3. Gently release the tabs on the sides of the fuel sender at the cover assembly. Begin by squeezing the sides of the reservoir and releasing the tab opposite the fuel level sensor. Move clockwise to release the second and third tabs in the same manner.
4. Lift the cover assembly out far enough to detach the fuel pump electrical connection.
5. Rotate the fuel pump baffle counterclockwise and remove the baffle and pump assembly from the retainer.
6. Slide the fuel pump outlet out of slot, then remove the fuel pump outlet seal.

To install:

1. Install the fuel pump outlet seal, then slide the fuel pump outlet in the slots of reservoir cover.
2. Install the fuel pump and baffle assembly onto the reservoir retainer and rotate clockwise until seated.
3. Install the lower retainer assembly partially into the reservoir. Line up all 3 sleeve tabs. Press the retainer onto the reservoir making sure all 3 tabs are firmly seated.

Gently pull on the fuel pump reservoir from retainer to assure a secure fastening. If not secure, replace the entire fuel sender.

1. Attach the fuel pump connector.
2. Fasten the CPA connector to the fuel sender cover.
3. Install a new external fuel strainer.
4. Install the modular fuel sender.
5. Install the fuel tank in the vehicle.
6. Connect the negative battery cable.
7. Pressurize the fuel system and verify no leaks.

Hope this help to solve your problem (remember comment and rated this).

Did you have the head checked, they have been known to break inside the runners . I always used a vacuum fill system when working on these, jack up the pass front corner when doing a coolant refill, that should eliminate an air lock If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

Try cleaning the track it runs on, then lube it with a spray lubricant. If that doesn't do it, it may be the motor itself.

Inspect the wires make sure they are connected properly on both ends and the wire casings are not damaned, cracked or melted. If they were put on the wrong plugs that should trigger a ses light but worth checking. make sure all the vacuum lines are connected andnot cracked. with the vehicle running use a spray bottle and spray aroung the vacuum hoses for wear (cracking) and the bottom of the throttle body to see if the vehicle bogs down, if so you need a throttle body gasket. You just need to check a few things to check.

You can buy the valve and cap at any professional auto parts store like NAPA. The bigger question is how you're going to replace it if the system is filled with refrigerant. Your best bet is to find a shop that has the special tool that can replace a valve core without having to evacuate the system. That'll cost less than removing all the refrigerant and refilling.

You may have left an air pocket in the system

Stop Lamp Circuit Description The STOP HAZ fuse in the IP junction block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to the center mounted stop lamp (CHMSL) and both left and right stop lamp assemblies. The left stop lamp is grounded at G304 and the right stop lamp is grounded at G304. Check the ground ! Testing an not guessing is the way to find the problem .

You need to hook up a scanner and see what is going on, any fault codes and such. Check fuel pressure, check the fuel is being injected, check to make sure the camshaft belt (if it has one of course)is turning and so on.

Engine sensors , mass air flow , coolant temp , also fuel pressure and flow . Suggest you have a qualified repair shop look at it with scan data . 056 Engine Hard to Start or No Start Misfire Scan Data 058 Engine Hard to Start or No Start Lean Fuel Condition 059 Engine Hard to Start or No Start Current Test for Fuel Pump 046 Engine Hard to Start or No Start Scan Data for No Start

It could be almost anything - immobiliser, engine management, broken wire somewhere, a relay... No sign of life from the dash probably indicates it isn't the immobiliser but take nothing for granted. The problem should be approached diagnostically rather than throwing parts at the car. A wiring diagram and a test lamp or voltmeter to follow the circuitry until the fault is found.

service engin light doesn't mean to do a tune - up . It means there is a problem that is causing a emission problem . DTC'S - diagnostic trouble codes are stored in the engine computer ! Your best bet , take it to a qualified repair shop .

You might try replacing the PCV valve. . .just a thought.

sounds like the seals are dry I used 10w 30 oil in mine and the squeaks went away maybe you have a bad pump
