It's probably easier to just unbolt the bed. Disconnect the fuel filler tube. Disconnect the tailights. And pull the bed completely off with the help of three friends. Just be careful w/ the back of cab and the bumper.

That's how I replaced the pump on my S-10 anyways. Didn't have to drain/drop tank, etc. It was all right there in front of me in an easy manner to work on.

 

Oh yeah, you'll need some saw horses to set the bed on.

 

Thanks SO much! I guess I won't be doing this job myself then :eh: i only helped my shadetree mechanic dad & didn't really do any of the work. My husband is mechanically challenged so usually I'm the 1 identifying noises, problems, etc.. on vehicles. lol.

Thanks again!

 

Looks like a moderate PITA

That's not fun :huh:

 

That doesn't look fun at all!! :-( & here I looked at ehow.com and it sounded so simple. Those pics have me scared. I think I will have to leave this to the experts or at least someone more talented than myself! I guess this goes back to the don't believe everything you read. lol

Thanks again!
Here's what they showed;

InstructionsThings You'll Need:
Standard end-wrench set
Step 1. Pull the truck up on blocks and activate the parking brake.

Step 2. Slide under the truck and locate the fuel pump. This is located under the driver's side on Titans.

Step 3. Unplug the usage cord from the side of the fuel pump. You may have to lift the front clip on the plug, as it is what keeps the plug secured.

Step 4. Loosen both sides of the fuel pump with an end wrench and remove the pump. Cover the input valve side with your finger to prevent too much fuel from leaking out.

Step 5. Wipe both the input and output valve with a clean rag to remove any sludge and debris.

Step 6. Slide the new fuel pump onto into its slot, and tighten both sides. Make sure not to get either of the valves cross-threaded.

Step 7. Replace the usage cord plug. Make sure that the latch is completely secured.

 

Yeah, let me get my "usage cord" and "end wrench" ready.

 

You DO NOT need to remove the bed...

Dropping the tank is pretty easy...there is enough slack in the lines and vent hoses to get it pretty far down. Then you can see the lines and fittings, and disconnect them easily.

Make sure the tank is as empty as possible...it will make it MUCH easier. Siphon it if you must...drain it.

Once the tank is out form under the truck, the fuel pump is quick and easy to change.

I did this a couple months back I made sure it was as close to empty as possible. Then I took off the skid plate it, then the 2 belts its has pretty much comes down from there. It does have enough slack to allow you to reach in and disconnect the lines and it is a 2 person job or at least it makes it easier. I had to replace my pump now I cant get the stupid chk eng light to come of it says there is a vacuum seal leak ???? I check a couple of times and replaced the gasket and reset the ECU and it is still there got to do some research good luck hope it works out.

 

I did both my lincoln mkVII and ford rangers fuel pumps by dropping the tank. I knew mine was on it's way out due to the loud whining so I went ahead and bought the pump and drove the car and truck until they were really low on gas and dropped them. Not too bad of a job. The lincolns was the easier of the two though because it was at the very back of the car and it was a fairly square tank whereas the ranger had a long skinny tank that ran down the side of the frame(like the titans, just MUCH smaller) and was shaped awkward. As big as the titans tank is I think it would probably be a beast of a job though.

 

C'mon guys, it doesn't look THAT bad...
Certainly easier than installing a leveling kit, maybe a couple notches above an oil change.
It is interesting that Nissan didn't think about this little inconvenience. I changed the pump housing in my SE-R in 10 minutes. Pull up the back seats, take out 3 quarter turn screws, plop, out comes the pump. Oh well.

titanhot - are you 100% certain that the fuel pump is the problem? Not being a hater, just not that common of a problem with these trucks.

 

No I'm not 100%. When my husband was driving it, it stalled in the intersection. I went over there, it would turn over, sputter & die. I told him it sounded like something with the fuel pump (i'm not a mechanic). My brother, is a manager for an automotive center at a retail store & his brother in law as well as my friends husband came to try & help (all 3 are decent shadetree mechanics, tho my friends husband thinks he's a pro).

Anyway, long story trying to make short... he said I was out of gas. I went & got a gallon & it started & ran. My husband took it to the station & filled it up. Drove home no problems. I went to the store 4 blocks away a couple hours later. Made it there fine. Came out of the store & it did the same thing.

We towed it back home & it is sitting there waiting for me to do something about it :-( (I miss my truck!!) So the consensus is to start at the fuel filter (cheapest) & then if that doesn't work go for the pump.

My friends parents have a Titan to & the sensor that shows the fuel level went bad. Then she said it got to the point where they couldn't put fuel in it or something ( I don't completely understand this one)

At this point I'm trying to find someone who will do decent work & not charge too much, as my friends & relatives aren't jumping at the chance.

If you have any suggestions of what it could be besides this or know of some common problems I will take whatever ideas anyone has!!! (especially if its cheaper!)

Thanks to all!!!

 

That sounds strange. If it was the pump you'd think it would be making a loud whining noise(every bad pump i've heard sounds like that) and it would not have worked even when you added gas. I'm wondering if either A: you might have got some air in the fuel lines when your husband ran it out of gas or B: You might have a loose line/connection somewhere that's causing it to work/not work sporadically. Is it throwing any codes at all?

 

Well there are a couple sensors that can cause this kind of grief. Could be problems with the MAF or the crank position sensor.
Heading down another path, you might be seeing the beginning signs of IPDM relay issues, that one is a quick check and free (swap it with another relay that you don't need, like the fog lights).

 

It doesn't look hard to do guys. I would just make sure you have an extra set hands and take your time doing it. You don't want to damage the FSU. Hell you might as well change out the FSU while in there seeings how they tend to go bad.

 

I need help… I have a 2004 Nissan Titan LE the connector to the fuel pump assembly is cut and missing. Can anyone help me with which wires go to which.

There is a total of five wires that lead to the outside of the fuel pump assembly: a black, black with yellow strip, yellow with blue strip, black with pink strip and pink with red strip

Inside the fuel assembly is five wires that are different in color: a larger blue and black wire that go directly to the fuel pump, a pink. light yellow and a light tan.

Any help will be greatly appreciated

Thank you,

David
