fuel pump relay

[mbailey]

do these usually just go out all at once or can they just start causing problems?

[Briano1234]

Yes to both. They can start to go flaky, then fail.

[Calimus]

They either just crap out, or they will start getting very hot and causing the pumps to slow down or sputter at random. Hope that helps

What's the car doing?

No start? Hard start? Drivability problem?

If you let us know the symptoms, chances are somebody here has been through it. We could be chasing relay problems forever.

Noises from the fuel pump can be caused by a faulty fuel pump, low voltage to the fuel pump or an obstruction in the line or the pick up in the tank. There isn't anything difficult about any repair in this area. Get under the car and have somebody turn the key to the on position and listen for the noise. It will be quick so listen carefully. If you must, then start it. If it's the in tank pump then remove the rear seat. Two screws at the base of the seat and it's out. There is a round panel with three more srews. Remove them for access to the tank. Now your looking at the fuel pump carrier. At this point I would check for voltage across your fuel pump wires. 12v or better is necessary. once voltage is determined then remove the fuel hoses, wires and the carrier. Careful pulling the carrier out of the tank. The fuel sender is attached and must be twisted a little to clear the opening. Check for debris in the screen at the bottom. If you are not squeemish about fuel and electricity, you can turn the key and listen for you noise also. Fuel pump replacement is pretty straight forward from here. Let us know how everything goes. If you need clarification just post again. Don't worry about hijacking posts here, we all do it and it's all friendly. Good luck.

How-to change your in-tank fuel pump.


###########################################################################
WARNINGS

all your tools ready.

OPEN YOUR TOP

###########################################################################


1. Make sure that you have 3/4 or less of a tank of gas

2. Disconnect the battery.



3. Open the gas cap to vent pressure.

4. Remove the 2 phillips screws that are holding the rear seat bottom in place.



5. Remove the rear seat bottom

6. You will see a black circular cover held in place by 3 phillips screws.



7. Clean the cap off of crud and dust the area around the cover, you don't want that falling in to your tank.



8. Remove the cover screws and pop the cap of with a flat blade and your hand.



9. You will see 2 hose connections and a electrical connector.



10. If the hose clamps are original they will need to be cut off with a pair or diagonal pliers then gently push the hoses off the tubes, they may spit a bit of gas.
11. Remove the electrical connector by wiggleing the rubber socket (do not pull on the wires).
12. Clean all the crud from around the fuel pump cap.




13. Take some duct tape and cover a large flatblade screwdriver tip.
14. Use the flat blade to wedge in one of the notches on the rim of the fuel pump cover and smack it to the left (counter clock wise )untill the cap will pop off a bit. (you may have to smack all 3 tabs a bit to loosen.



15 Gently pull up and unwind the In-tank and float assembly out of the hole, you will have to wiggle it to clear the float arm and possible the sender unit do not be over forceful, be careful not to let the pickup screen fall back into the tank.
Be careful if you drop the strainer in the tank you can use a mechanical fingers to get it back out.




16. With the Fuel pump safely out cut the lower clamp on the rubber connector off, or remove the hose clamp.

(on mine I usually replace that connector hose with a piece of 5/16 inch fuel hose cut to the same lenght.)




17 disconnect the Fuel pump connector.
18. Pull the pump off the connector.
19. Place the new clamp on the hose prior to replacing the new pump on the hose.
20. Tighten the clamp and replace the strainer.



21. Reconnect the electrical connector to the pump.
22. Clean the o-ring gasket and the lip of the pump.





23. Lubricate the o-ring with petroleum jelly.
24. Wiggle the o-ring back to the top of the cap.



25. Gently replace the pump assembly in the tank be mindful to get the float in first and seat the o-ring (critical to get a good seat on the ring to the tank).




26. The pump will seat in to the locking tabs at the 5:o'clock position , then apply a little downward force clock wise to start the pump into the lock to catch.
27. Once the pump is caught on the locking tabs, then using the screwdriver and a hammer again smack the pump cap to the right (clock wise)



28. Once the pipes are facing the back seat as in the 6:30 position
29. Replace the hose and clamps.
30. Replace the electrical connector.



31. Reconnect the battery and start the car and rev it has the primary pump stopped whining? GOOD.



32. Replace the cover for the tank access.
33. Replace the rear seat.
34. Fasten the rear seat with the phillips screws.
35. Place the top up, and drive away.
