Can be a bad pump? I need to replace it again?

Was pump an O.E.M or aftermarket? if aftermarket did it come as complete assembly? with FTT ? see diagram

181 and 183 faulty fuel temp and fuel level sensors

I believe it's an aftermarket pump. I ordered it from NAPA. The only thing that I got was the pump by itself nothing else came along with.

Codes will stay till FTT is repaired or replaced

How to remove the fuel strainer off of fuel pump?

Remove fuel pump from tank. Can be accessed through a cover plate under rear seat. Why ?

I have tried everything. The dealer is stumped, other mechanics are stumped and I have ruled out that the gas pump is emitting some kind of electrical interference (I think). When I am at the gas pump and after I have finished pumping the gas, put the cap back on, the car won't start without being given alittle bit of gas. This is very unusual and not the way the car is supposed to start. I can then drive away 10 feet, shut off the car and then it will start fine. It starts fine anywhere else at anytime of the day no matter how long it has been sitting but it won't start after pumping the gas at the gas station. I have tried filling at different intervals (empty to full, half empty to full, etc...). It still won't start right away. I have tried sitting in a parking lot with the gas tank open and it will still start. I have tried just sitting by the gas pump, turn off the car, wait a few minutes and the car will still start. I have tried turning the key to "on" for a few seconds and then off again and then to the "on" position for a few seconds and then off again and it still won't start while at the gas pump. The dealership had run the error codes and replaced the spark plugs and a sensor and a filter but it still didn't start at the gas pump. Could it be something in the gas tank that is loose that is being disrupted by the gas being pumped in? What is left to look at?

You're problem pretty much has to be related to the pump itself. My guess might be that the pump is reacting to sudden temp change in the fuel but you're going to have to pull the tank down to investigate further.

My car started giving me problems after I took it on a long road trip. It started overheating. At first they told me it needed a radiator flush, but I couldn't afford it so I kept driving it. After a few weeks, it wouldn't start, so a relative who is a mechanic told me it was the gas pump that needed to be replaced. I had a friend take out the old gas pump, so now the car doesn't have a gas pump at all. I had it towed to Pep Boys, and they started asking me for parts not even the dealership carried. Now I'm stuck with the car without a gas pump and have no idea how to get it running again. Is it possible to order a used gas pump online or is it only from the dealership that I can order it?

Where's the old assembly?

Fuel pumps are part of an assembly and are a commonly-replaced item. All auto parts stores will have them or can order them. The question is whether it will come installed in a new housing already, or if it is just the pump and motor that has to be installed into the original housing. Often a new pump is available both ways.

There are other parts that may need to be removed, but they are not replaced. Since those are not commonly replaced, they will usually not be available at auto parts stores. Those will be dealer-only items, and even they may have to special-order them.

You can also find missing parts at a salvage yard, but if selling you a certain part renders the rest of the fuel tank unusable, you can expect to have to buy the entire tank. Often they will have a tank that was damaged in a crash so it's already unusable. They'll sell you parts from those very inexpensively.

The dealership can order any part that went into building the car, as long as it's still available. Normally it's Fords that parts aren't available after just a few years. They do a very poor job of supporting their products. Your car is 12 years old. That's a fairly long time to supply replacement parts so what you need may be no longer available from the manufacturer unless the same parts were used on much newer models. That's when a trip to the salvage yard is needed.

Auto repair shops routinely deal with the salvage yards too. All they have to do is figure out the parts that are needed or missing, then call the yard with their list. It may take a day to have someone remove them from the car, but then they often deliver them right to the repair shop.

How do you replace the fuel pump and filter?

Hi freakdogslim, Here are the procedures. FUEL PUMP, FUEL LEVEL SENSOR & FUEL FILTER -

Removal & Installation 1. Release fuel pressure. Remove access cover located under rear seat. Disconnect fuel hoses and electrical connector. Remove fuel pump assembly screws. Remove fuel pump assembly from fuel tank. 2. Using a screwdriver, disengage clips holding fuel pump assembly to chamber, in order shown in illustration. See Fig. 3. Disengage fuel tank temperature sensor wiring harness. Disengage clips holding fuel level sensor to chamber. Pull fuel level sensor upward. 3. Disconnect fuel pump harness connector. Disconnect hoses from fuel level sensor unit. Pull fuel level sensor unit upward and out of chamber. Disengage locking tabs holding fuel filter into chamber. 4. Pull fuel filter out of chamber. Using a screwdriver, remove fuel pump bracket. Pull fuel pump out of fuel filter. To install, reverse removal procedure. Tighten bolts to specification.

I was replacing the fuel pump Assembly and I found a o-ring laying and not sure where it goes,and is there only one? Aprox 7/16ths across

Is it a big o ring it goes between the pump module and fuel tank

No its not the big one at the opening this one is about 7/16ths across

I cannot locate any other o rings
is it a rubber o ring
I would check the quick connector if had it fallen put of it
i should have two inside of it

yes its rubber, I do not see any o-rings inside of the connector lines would both lines take one or just the one from the pump?????? as I stated I only found one o-ring

I’m trying to recall how or if any small o ring is in the fuel pump module
and I cant come up with any thing else
is it possible its an extra part that some one put it in the box by mistake

replaced the fuel pump. Car started ran for a few moments then stalled and will not start. Gas is getting to fuel injectors but seems to sto there? Car will not restart

are you certain its a fuel problem? if its getting to injectors and stops there then injectors are either clogged or not pulsing. will need to test each injector. may want to check compression on cylinders and check spark, may not even be fuel related issue.

1998 Nissan Sentra 4 cyl Automatic

My car did not pass inspection because it needs fuel module control. I bought it and took it to my mechanic, but he cann't find where it should be installed. Can you help me, please?

OV

I am not sure what you mean by fuel module control. Where did you get it and what is the part number. A picture helps, too.

I have gotten down to the fuel pump in a 1996 Nissan Sentra, but cannot find the clip that releases the assembly. I have taken out the float and can access the pump, but cannot seem to release it to remove it. Any suggestions? A picture would be great.

Thanks.

REMOVAL
1.Release fuel pressure.

2.Remove inspection hole cover located under the rear seat.

3.Disconnect fuel supply tube, return tube and electrical connectors.
4.Remove the six screws.
5.Disconnect fuel tubes and connector, then remove fuel gauge assembly.

6.Remove fuel pump with chamber.
*Pull up the front of the chamber.
*Slide chamber forward.

7.Remove fuel pump from chamber.

INSTALLATION
To install, reverse the removal procedure.

CAUTION:

*Tighten bolts to specified torque.

2.0 - 2.5 Nm (0.20 - 0.26 kg-m, 17.4 - 22.6 in-lb)

*Always replace O-ring with a new one.
*After installation, run engine and check for leaks at connections.

Thanks rasmataz. I've tried this but with no luck. The chamber is held in place by something. I'm afraid to use too much force for fear of snapping something off. The attached photo is what I am looking at - "front" is on the left.

I was able to get it out there is a clip at the top, on the rear end of the chamber.

Thanks again.

i was driving my car one day and it was running fine until i went to a service station. When i pulled out of the yard the car started to rear up like i was pressing gas reallly hard but i wasnt, and it did this all the way home even when i pressed brakes. I left it for a day or two then decided to try again it was fine for about three days then it turned off when my gas level got to low i am just wondering before my husband changes the fuel pump is that the problem????

Have your husband clean the entire throttle body, including the butterfly and throttle cable. Sticky carbon buildup within the TB probably caused the throttle cable stayed engaged even when you remove your foot from the accelerator pedal.

how do u remove and replace a fuel pump in a 94 nissan sentra

You access it thru the backseat its a simple job when you get there

I did that, I have everything taken lose but I can not figure out how to get it out of the bracket inside the tank

My car began cutting off every now and then starting a few months ago. It wasn't frequent and only happened when I first started the car, drove down the street and stopped. It kept cutting off more frequent so we replaced the fuel injectors, and cleaned the throttle. Check everything else, car seemed to run okay for a while. Then the car would have trouble starting, and just wouldnt fire. Finally it would not fire anymore and I had it towed to a shop. They said it cranked up fine and the fuel pump was working. A few days later the car wouldn't fire anymore unless I banged the fuel tank a few times, then I would hear the pump kick in. Also, if I sprayed starter fluid to the intake filter she would fire, so this let me know it had to be the fuel pump. This process worked for about two weeks until she gave out. I wanted to make sure there was nothing else I could do before I replace it?

Check the fuel pressure before you condemn the fuel pump/and remove the back seat and double check the fuel pump connector-

Or disconnect the fuel filter turn key to On and observe for fuel -No fuel the pump is defective-

Car standing a year for penalbeating try to start but carbarator cant get fuel changed petrol pump still it doesnt changed petrol fitter still nothing what can be the problem?

Your car doesn't have a carburetor. It should be fuel injected.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

I have a nissan sentra, 1990, manual transmission, 1.6L

the car has always ran really well. couple of days ago put a new stereo in, it died. replaced battery, ran for a day and half, died, replaced alternator, ran a day died. it will start and run about a min then dies, won't start again unless i wait about an hour then does the same thing. I'm moving on to the fuel system. is there directions on diagrams on how to change the fuel pump and fuel filter. I had both barrery and alternator check, they are fine, should be since they are new. anyway any diagrams or directions would be of great help

fuel filter wouldn't cause engine to stall. inspect your fuel pump relay before replacing your pump itself.

thanks for the prompt reply. it is wonderful to hear an honest answer but you kind of lost me. what the heck is a pump relay?

a relay is similar to a switch, only the vehicle's computer turns it ON or OFF instead of a human. when the relay is activated, it allows the component that it controls to operate. if for some reason the relay fails, it can no longer allow the component to operate either. your vehicle's fuel pump relay is located under the left side of the dash and should be green in color. It will be a large plastic square shaped item plugged in, it just pulls out much like a fuse does. you can go to our "first things to check" page to learn how to test an electrical relay

one of the fuel lines was leating fuel while car was running pulled both lines and replaced both about a few hours later now fuel pump is not pulling fuel to engine. I can add fuel into the intake and it will run till fuel burns off how or what would be needed to check out problem??

Recheck the lines-do you hear the fuel pump come On when key at run position? If so check fuel pressure with a gauge not the eyeball or thumb method.
