1 Year of Toyota PARTS CANNON...Long Crank When HOT? (Part 2 - 3rd Gen 4Runner)

Customer approved the replacement of the suspected WEAK FUEL PUMP that's causing a severe lean condition and hard warm start on this beautiful 2002 Toyota 4Runner.
Replacing the pump involves dropping the rusty fuel tank.
How can we be 200% CONFIDENT that we're replacing the RIGHT PART?

Moral of the story: Pay a diag man dont fire the machine gun parts cannon 😁 great video 👍

[@Bellathebear777]

Pump was just working. Now no start. Tap, wack the tank jus below the pump, key on.

[@JoseSilveira-newhandleforYT]

Great conclusion, Ivan! Never thought of checking pump speed by counting current peaks. Makes sense now :-) PS: I would have cleaned those battery terminals, but the owner is quite capable of doing it.

[@PineHollowAutoDiagnostics]

Terminals had some kind of white protective coating on them 😉

[@JoseSilveira-newhandleforYT]

@@PineHollowAutoDiagnostics Ah, OK! didn't catch that in the video. Probably lithium grease. Sorry for the misunderstanding.

[@pootthatbak2578]

Sawzall? Dont you mean grinding wheel? There was a gasoline tank right under the floor

[@major__kong]

I was thinking the same thing except Dremel with a cutoff wheel. Before cutting, though, you need to check for things underneath that shouldn't be cut like a skin stiffener or stringer. Those dimples in the floor are stiffeners. Unibody vehicles may have longerons or stringers that don't just stiffen but also are the strength. Since this is an SUV, I doubt there's any structural aspect to that floor. Worst case is that it might oil can after cutting some of the dimpling out.

[@lvsqcsl]

@@major__kong Absolutely. That vehicle has a frame.

[@johnchambers12]

I used an air nibbler on my 2003 Saturn when i had to replace the fuel pump in upstate NY with all of the rust i found under the car. I had to make an access cover but it worked great! So I’m on the team that would open up the cover hole to do the replacement!

Thank you for showing how to test the pump itself with the Pico. I had no idea you could do that. Great case study.

[@pootthatbak2578]

You can buy cheaper oscilloscopes than a pico brand.. maybe 200 bucks for a stand alone chinesium scope plus 200 bucks for probes you could start using a scope

[@russellhltn1396]

I was glad to see it, but surprised by the results. I expected to see it "missing" on one of the poles.

[@goodtimejohnny8972]

Be careful using the hoses supplied with the fuel pump. One would think that they are designed for fuel but I had one collapse about 12 hours after installation. After I installed the proper fuel line everything was just fine.

[@PineHollowAutoDiagnostics]

That's why I don't replace any unnecessary parts haha

Nice fix Ivan. It’s amazing how the computer compensated when the fuel pump was putting out half of the pressure the truck had when new!

I do the same with wire. I usually throw away whatever came with whatever widget I'm installing and use marine grade wire instead. Best thing you can do to avoid the green crusties. That and using dielectric grease on terminals and crimps :-)

[@jacksautorepair]

When checking fuel pump, always take into consideration the battery condition and alternator output. I had an older Dodge Caravan that had weak fuel pump flow barely trickling out and a weak red spark. It was also cold weather below freezing and this thing wouldn’t start even with starting fluid. Spark plugs wore out so I installed new plugs and wires. Replaced coil too, but still had weak red spark and then noticed very little fuel pump flow. Connect the jumper cables and it started. Recommended a new battery and off she goes. Got a call a month later and battery was stone dead. Alternator took a crap. Before checking anything electrical, make sure the battery is good and alternator is fully working! Avoid these comebacks or misdiagnosis. Oh when customer says I just replaced alternator or battery. That don’t mean anything. Sometimes they claim I just installed a new alternator and battery 6 months ago, when it been 3-5 years ago. But replacing parts doesn’t mean it’s good anyhow. When customer claims it can’t be this or that, you must explain this to the customer. Battery cranks car, these days it doesn’t necessarily mean the battery is up to specs. The 12v battery system has met its limitations. Cold weather tells the tale.

[@johnclamshellsp1969]

Long ago when working at a dealer, never failed tanks all full and bad pumps, all warranty. Drain the tank, no extea booked hours, and every custumer blamed us for stolen fuel. Ohh what fun.

[@leonardodavinci303]

Fantastic master class in lean condition caused by low fuel pressure. Great diag followup on the new fuel pump. Learned alot. Thanks.

[@lvsqcsl]

I loved it when you asked why an engineer couldn't have made that access cover bigger so you could remove the fuel pump WITHOUT dropping the tank. Since this vehicle is an older model and OEM parts might be in short supply, I was fully expecting a Russian repair. I will take it. GREAT VIDEO!

[@jdesaavedra0432]

On critical parts, if the OEM is in perfect condition after 15 years, I keep them. Just because they throw in some segments of hose doesn't mean they arent chinesium. Good call on the fuel pump. Every symptom pointed to a fuel pump from the start. I had this exact scenario with a GMC van 20 years ago. I paid a local shop to diagnose the cause of these same symptoms and ended up paying for a spark plug wire and was returned a lazy vehicle that got great mileage. It was a pre-OBD II vehicle. After a while it got so hard to start I pulled a fuel line and nothing came out. Pumped out 30 gallons of fuel because at the end it would only run when near full. $20 fuel pump make it like new. I'm a much better mechanic now I have KZbin and time to think. I no longer send things out for repair. Thanks for all you do for DIY and also for shops willing to listen.

[@johnchambers12]

I had a customer call me for a new fuel pump that was an in the tank , it was pumping no fuel but running like a champ in the tank. I tapped a screwdriver on the bottom of the tank and heard a hollow sound , with a fuel sending unit saying it had a half a tank. I added 5 gallons of gas to the tank and the gage didn’t move but the car started and ran. She settled for filling the tank and not replacing the sending unit. Two years later she still liked counting the miles for approximation of gallons in the tank and not replacing the sending unit

[@mrb1864]

Nice pleasing result and the Denso pump kit made it easy & confidence inspiring. Right choice of replacement parts is almost as skilled as diagnostics, you really need know who makes/packages what and keep up with constant supply source changes of aftermarket have half a chance of buying wisely . OEM parts on the important stuff pretty much always pays off . If only Toyota had made a full access panel under the seat .Dropping the tank for a pump was pretty stupid engineering design choice ...

Quite a bit over my head but I love the way you isolate each step in your thinking and follow with a test to confirm. You never really chased the rabbit down the hole. You just used experience and the proper tools to read this problem like using a GPS to plot a trip. Very cool! You know your stuff. I am running into the same issue but have not even begun to drill down. Starting with spark plugs & fuel filter.

That low idle at the end was from losing the idle memory from disconnecting the battery. Happens to mine almost to the point of stalling for a few trips. One day I'll get around to cleaning the throttle........

[@mikeluscher159]

I went through this with my 2009 Scion xB (2AZ I4) Hard starting, vapor locking, long crank I sent the injectors out for cleaning and flow testing, they were badly restricted (they cleaned up) I had an exhaust leak at the donut gasket, throwing off fuel trims (I repaired) Then, finally, at 285k miles, the (in hindsight weak) factory fuel pump bit the dust Replacing the pump breathed new life into the old 📦 Some repairs are one step forward, two steps back

[@dharley189]

Great job explaining how to positively ID a weak fuel pump. I’m surprised it lasted a year without failing. Also surprised all those parts would be replaced without once testing fuel pressure. I’ve been around since before OBD 1 & 2 so that was pretty routine to test FP pressure first. And a Schrader valve would have been nice rather than assuming T’Yota pumps don’t fail 😳 I applaud you for working in that kind of weather. If we had that much snow we would have been cleaning floors and tools at our shop cause no one would drive in that mess. Heck I won’t drive in it anymore either. 🥶🥶 Del in Ky

Great job Ivan! I had a 97 civic that was my personal car. Only occasionally would set a lean code. Started fine, good power. Ran my tests with my pico and was all good. I did replace the fuel filter approximately 3000 miles prior to this issue. The filter was a high end filter. After replacing the filter again my lean fuel trims were back to normal. Sometimes you get crappy parts from name brands.

Since the car has a history of evap related codes it might be a good idea to smoke test the tank while it's on the ground. One of the rubber gaskets or a steel evap line on top could have a leak you wouldn't be able to see with the tank installed.

[@pootthatbak2578]

[@flatdaddio]

Awesome! My used car I purchased had the "hot soak" issue and was running lean. It would misfire after sitting 15-20 min. also misfire after driving about 10 miles. It would sometimes throw a code for misfire cylinder 5. Cylinder 5 was the last cylinder on the fuel rail. The problem was someone changed just the fuel pump not the assembly. They failed to properly connect the pump to the fuel line in the tank. It was losing fuel pressure and would also get air bubbles in the fuel line. After replacing the fuel assembly my car ran fantastic! 2004 Lincoln Town Car with 101,000 miles Florida car. No rust! lol

Hi Ivan, same exact issue on my Camry 11. I was between fuel pump and injectors. I took a leap of faith 😂since a snowstorm was arriving on the same night and don’t have a garage, so I replaced fuel pump and that was the issue. Interesting enough as your previous diagnose, I could run the car(poorly) but I could, and long fuel trim was around 35%, long startup after hot! Well can’t really complain when this issue happened car was already at 300k . Keep up the great work and videos! 👍

Another great video showing the proper diagnostic process, as well as the value of the scope in diagnosing the problem and proving the solution.... I will be taking a long trip in my European car (177K miles) this summer and will use the pico method to verify the operation of my ruel pump. The good news is that I don't have to drop the tank to replace it, just make sure that I have a low fuel level. Thanks...

great use of your problem solving skills and the use of the pico for confirmation put a big hole in the floor oem people

[@thomasbrandon8029]

Nice job, current ramps will usually tell you all you need to know about the fuel pumps condition, in this case current was low because the pump was either leaking internally or could not reach the RPM required for good fuel pressure. I usually would do current ramps on fuel pumps with intermittent no starts, you can usually see the current drop out when it hits the bad segment(s) of the pump.

[@frankmcdonough3351]

As always excellent job of Diag, I would have replaced the hose and clamps on the fuel pump.

[@RussellBooth1977]

I know that in my 5.7 litre Chevrolet LS1 V8 powered Holden VY SS Commodore that I was worried that the Long term fuel trims were sitting at about 21% & the engine almost didn't start the morning that I took it to the mechanic to get the annual pink slip registration inspection done on December 20 last year because in the past a bad fuel pressure regulator has caused the high fuel trims plus a check engine symbol to turn on the LCD part of the instrument cluster. I was getting at least a P0171 and sometimes a P0174 lean code. This time the fuel trims went back down to the single digits when I did the 40,000 kilometre or 24,000 mile fuel filter change,I blew it out & it was full of dirt. The fuel economy display has also been showing a higher than normal fuel consumption readout as well but it the fuel trims are back to normal then I'm not worried. It uses the SAE J1850 VPW pre CAN GM OBD2 protocol as well,not the ISO15765 CAN OBD2 protocol which the 6 litre L76 V8 engines were ran by in the series 2 VZ SS Commodore in 2006 !

[@DerDuckPond]

First couple of times watching a PHAD video I thought it was perhaps too slow, as you explained every step and showed why this was tested and when. Now I understand your love of teaching people about diagnostics and the importance of not skipping small steps and checks to avoid incorrect conclusions. The most frustrating thing about your videos is the failure of automobile manufacturers to make small changes that would vastly improve access to parts of diagnosis of faults. I understand that it saves a few cents, and that adds up, but having a auto that’s built to easily diagnosis and repair will potentially get you a reputation like Toyota built up over time and increase the price you can ask for your vehicles.

Be glad you’re not working on a mid to late 80’s FI Buick. No access ports, no nothing, and the tank fill and vent would go into the side so the tank would need to be drained to at least a 1/4 before removing. They were like pancakes.

13:44 low idle on a Toyota of that vintage? It needs the throttle body cleaned - you just forced a re-learn by leaving the battery unplugged, so I bet it's "forgotten" all the learned compensations for the throttle being dirty AF. My 2005 Camry is the same way so I clean the the throttle every 30k miles now, only takes a few minutes. Probably only really need to do it every 100k but it's easy. Still, at 176k, this Toyota DEFINITELY needs it.

[@rjm7168]

They wanted make sure that the fuel tank would always have to be removed to change the fuel pump. I can see reasons why but at least they gave you an easy way to test it (the fuel pump) by giving you an access hole to the connector. That there's an access panel at all makes me think that they thought about it and it might have been deliberate.

On the cars, yes. On the SUVs nope. They are all like this, 96-2024 4Runners, FJs, GX and so on. So frustrating.

[@topher8634]

@@Gadget0343 I can't recall if I ever replaced one on the Toyota SUVs. Probably have, just can't remember. I always hated doing the ones on the Plymouth/Dodge Neons. The fuel pump module was located on the bottom corner of the tank. You didn't have to drop it, only lower it a little. But because it was on the bottom, you got a face full of gasoline. If it failed with a low level (which is hardly never it seems like) you could jack the vehicle up on that side so the fuel would run to the opposite side. Then it was like a puzzle trying to figure out which way to twist the assembly to extract it.

[@davidhollfelder9940]

Deja Vu .. I put a new Denso pump in my ‘02 Odyssey .. yep, the RPM should be somewhere between 6000 and 7000. I tore down the old, 18 year old/180K miles pump, and found the commutator was extremely worn out.
