Replacement fuel pump

The 4th item has the pre-filter screen. It also matches the application guide on the Denso site.
 
I just ordered the same one Gerdo did off of Ebay for a little less.. Same prt#.. Don't know about ya'll but I'm a little anxious about starting this job.. One of us needs to take some pics and post on here the step by step procedure to help others... (hint hint everybody but me) I only have a stupid phone soooo......
 
I just hate working with gas, you smell like it for days.

I'm actually thinking about cutting a larger access panel and R&R from the back seat.

It will allow faster repairs in the future too.
 
I had about 5% hope that replacing the fuel pump would cure my issue.
Upon further review, cutting and making a larger hatch to change the pump thru the inside was too much work and also the chance of getting gas inside was too great. I decided to drop the tank.
Today I did replace the pump and so far so good. After a half dozen warm re-starts, it fires up instantly!

Why didn't someone tell me to replace the pump?!
 
I could rag on you for taking so darn long, but you got it fixed and now the thread is halfway closed.

Did you take any pics? At least post one of the old pump.

Now to get Baja to drop his tank to cure his hard starts, and to take pics to close the "engine cranks 3x too long" thread.

Please, rag on me. I gave it a 5% success rate (I was thinking more like 0% but wasn't positive).

By the way, The "engine cranks 3x too long" is my thread too.

Pictures? Are you kidding? Of what? All I had was a fuel tank, stinky old pump and like a hundred tubes, hoses and plugs.
 
WoooHooo!!!! This is great news! :driving::driving:

Any tips or tricks you would recommend along the way? How long did it take to drop the tank?

It was probably an hour job.
There the fill tube vent and a wire harness that needs to be undone from the top of the tank. Of course, most of the clamps are turned a direction that makes things difficult. The pump power gets unplugged from the access panel under the drivers side rear seat carpet. I also put a piece of plastic over the tank filler hole (held on with a rubber band).

I did buy/replace the rubber gasket around the tank/pump hole. I'm glad I did, the old one was not looking too good.

I removed the tank skid, lowering it with a floor jack.
Then lowered the tank, checking for wires, tubes and hoses (there are a lot to watch). I used a piece of plywood on top of the jack to protect the tank (~18"x 24"). My rig is high enough that I could slide the tank off the jack and onto my creeper so I could roll the tank out. It could also be dragged out on a piece of carpet of cardboard. (CAUTION: LOTS OF GAS FUMES THAT COULD IGNITE)

I had about 4 or 5 gallons of gas in the tank. It did want to shift due to the gas. Less gas would have been better but I had today open to work on it.
 
Wow, an hour doesn't sound TOO bad.

So are you certain this is the fix?!

Can I smoke a cigarette while doing this job? :biggrin2:

I'm pretty sure it fixed my issue.

I don't think that smoking would be a good idea.

Here is my write up.
*Support the tank with a floor jack
**Take out the bolts that hold the tank up
*Remove a bazillion hozes, lines and two cables
*Lower the tank, watch for the hose and cable that you haven't disco'd that are on top of the tank
*Lower the tank to the ground
*Slide the tank out
*Remove the pump
*Put in the new pump
*Reinstall the tank, remembering to hook everything back up
*Check to make sure you hooked everything up.
*Later that day, Check again to make sure you hooked everything up. (I kept wondering if I reconnected the line that is...)

Oh yeah, Wash your hands a bazillion times and get used to the smell of gas on your hands for a few days (I even wore rubber gloves).
 
Great information. I was reading your other post. I to am having a slow start and mine has around 170,000 on it. Just got it so I am reading ALOT of information about it.

Ditto here on the slow start at 165k miles. I located the Denso fuel pump and screen for $94 at Rockauto.com and installed it today. Total install time 3 hrs.

It was a snap to drain the gas tank. What I did was, open the line between the filter and pump (pressure side). It was the compression fitting one back from the filter fitting. Positioned a container to catch the fuel. I used a 5 gallon gas can. Then moved to rear driver's side seat and open the access panel under the carpet. unplug the wire to the top of the fuel pump assembly. jumpered positive to #4 and negative to #5. Took only a few minutes to empty the tank. I used a spare 12v battery and made the final connection of the (-) lead to the #5 terminal, since any spark would be well within the truck and nowhere near the gas tank and fumes.

Once in the tank I was surprized to see the newer version of the sending unit. Well, that's one less thing that I will need to replace. Which would explain why the clamp on the fuel tank fill tube (the big one) was loose. Someone had been in there once before. Thankfully I wasn't leaking any gas.

Gerdo, thanks for the headsup on the new gasket. Mine was shot. Other than breaking off one of the skid plate bolts closest to the driveshaft and having to drill it out, it went smoothly.

With 175,000 km on mine, it has to crank a bit( 5-6 revs) sometimes before it fires up.

One day, it didn't want to start at all but sounded like it was starving for fuel. By cringing totally and slightly depressing the throttle, I was able to get her to fire up. Only ever done it once to me but it leaves me highly suspecting a fuel pump replacement is/will be needed. If a mechanical switch could be wired in from the harness to externally pwr up the pump before cranking over the engine could I avoid long cranking start times?

Also handy if you accidentally run the tank dry and avoid a lot of starter cranking to get back running.
Silly idea?
 
So Drcoffee, did the new pump make starting any better?

The difference is night and day. It fires up nicely now. I dreaded the job because of working with gasoline and in the cold weather, but I'm glad I finally got around to getting it done. Yesterday (before pump installed) I stopped at a store to buy a gift and when I tried to restart the truck it struggled to start. Took 3 attempts to get it to fire and idle.

Thanks for the write up. I was hoping to do this without dropping the tank. Oh Well.
 
its too bad that Toyota did now make an removable panel in the truck to get to the pump
ive had several cars that did, (BMW , Volvo to name a few)

but Toyota was prob figuring that we would not replace the pump and a lift off body panel would have cost an extra 50 cents in production

Ha! Exactly what I'm thinking. My Subaru had a nice removable access port big enough to change the fuel pump in the back seat. 30 minute job at most. Thought I could do that on the rig but I shoulda known they wouldn't make it that easy on the 4runner. I mean, judging by the pain in the ass concoction to change the oil. [emoji52]

thread revival ftw. Lol

Plan on chanigng mine this summer as preventative maintenance. I've done it in my MK3 Supra and it's a really easy job actually. Don't think it would be much different in a 3rd gen.
