Tundra Long Start Fix with out Changing Flex Fuel Pump
Vložit

- 2018 Tundra has had Long start/crank problem each of the past two years. I think it is a fuel problem, not the fuel pump. ECU does not need to be flashed either. Hope this helps someone else.
I have a 2014 Flex Tundra. This issue started around 60k miles for me. Took to dealer and they flashed it two different times before someone truly told me what was happening. So I started running ONLY Ethanol free 89, been about 2 years I guess. I bought a car for work and don't drive it much anymore. Drove it last Friday and it had a long cold start (cold day) after work, ran rough and alot of rich gas smell and smoke for a minute. Watching your video for answers, I remembered i had filled up that morning and it was almost empty. Maybe that is what messed with it. Can't believe this is still a thing. 🤦♂️ It's the only complaint I have about my Tundra, love it otherwise. 128K so far.
Yeah it's the one wart o this thing for me.
Been dealing with this issue for literally a year and a half. I’ve put two fuel pumps, all new injectors, fuel regulator, flashed ecu, mass air flow sensor, spark plugs, battery and it’s still giving me problems especially now that it’s turned cold. I’ll be giving this a try today. I’ll report back tomorrow and let you know. Thanks
Anxious to hear out it goes either way
@@kedrevs4037 it did not fix my issue, thanks for the video anyway
Could be your coolant temp sensor
I just had my 2015 with 120K miles have the same issue. My local Toyota dealer claims they couldn't find the issues. IMO they really didn't try. They charged me $50 to tell me my battery was good but I told them from the start the battery was good and only 3 months old. I bought my truck from this dealership and I have always serviced my truck at this dealership.
The fix to the problem is a software upload and the fuel pump needed to be replaced. Cost me around $1100 to fix.
My local independent mechanic correctly diagnosed the problem just by describing the problem.
Hope it stays fixed for you
Very interesting. I have the same issue with my Flex Fuel, which I didn't know I had until after I bought it. It's not badged but was told by Toyota, some trucks received this engine. I went to Toyota and was told that there was a code showing on the fuel pump and that this was a "known" issue with Toyota but not enough to warrant a recall. They quoted quoted me $1800 to replace the pump. I had another service provider replace it for $1200. Long story short, I still have the same issue. Only when it's cold. I never run E-85 as it's not something a lot of stations in my area carry and had never had an issue until last year (85k on a 2019).
Mine didn't start until 120k miles, but the ethanol free fuel takes care of it when it starts
I bought my Tundra on your review, but got lucky and have a Y, so not junky fuel!
Wish I had the Y
I purchased my tundra in 2013, new, from Cars Direct. I clicked the non-flex fuel option purely as a guess toward simplicity. Interesting to hear your perspective.
Good Call!
thx having this exactly issue with my 2016 with 200K miles. I have been running e15 so that's a good possibility. I have purchased a fuel pump which I'm still going to install because of the mileage on my truck but at least this delays that repair maybe. :-)
Ty for the video/Info, I occasionally have long starts (only) after filling up. Live in STX and cold days are few. When the code came up, I changed out the PCV valve . May try Canister next. 2014 SRD 320K
Changed PCV valve and didn't seem to make difference.
Great information! I live in middle TN area, and have a 2018 and never had an issue til this winter season. I'm going to go with non ethanol on my next fill. Hopefully, it'll take care of the slow/delayed start. Thanks!!
Hope it works for you too.
Ran ethanol free for 2 years and it still done it, don't let it get to low of a level of fuel, I think that is my issue. Good luck
Good info. I have a flex fuel 2018 5.7. Never had the issue, but now I know what to do if it happens. Thank you.
Hope you never have to use that information
I had this issue on 2017 Tundra at 90k miles. Bought launch bi-directional scanner and triggered "relearn fuel density" function to reset to 0. No issues since. The trucks do not have a sensor. An algorithm is used to calculate the ethanol %...
What scanner did you use?
The launch bi directional
@@markschwinghammer2321I am looking into launch scanners. What Model number scanner did you get?
Same issue here as I’m speaking my trucks at the Toyota place and they want $1600 to fix it. They’re going to replace the fuel pump ECU and ECM. I’mgoing to call this morning and tell him not to start. I’m coming to get the truck. They want over $300 for two diagnostic test and they don’t know what’s wrong with it either. I’m gonna see if this works. thanks for the video.
Really hope it helps. So far, it’s been good for two months now without any long starts.
Did this fix your issue?
@@ClinesCraftedWoodworking I went and got the truck from Toyota and didn’t let them do what they wanted to do and my truck quit doing that and it’s been running OK ever since so I never done anything to it. Save myself $1600. It just did it in real cold weather, but I never did anything to it. It’s running fine.
@@joedonwilson6243 thanks you for the reply.
So just to confirm 100% if in the vin # if it has a W it’s a flex fuel model and the Y isn’t?
I’m looking to purchase one and on the car gurus site it says that it is but the vin of the vehicle has a Y so I just want to be sure 100% and thanks buddy for this video it really help shed some light 👍🏽👍🏽👍🏽
Can't remember who told me this, but I have found it accurate. A double check would be to put the VIN in Kelly Blue Book online. If it is a flex fuel vehicle, it will tell you in the engine description.
GREAT VIDEO! Exact same thing here. (nice truck btw) Going to fuel up with E0 tomorrow.
Hope it works for you.
@@kedrevs4037 Nope. Filled with E0 four days ago and have now run it about 300 miles. Tested 83.5% today before cold start. (sigh)
Going to try this out been thru so many thoughts and was currently looking for a video to replace fuel pump myself.
Hope it saves you the pump.
You never want to run your vehicle down close to empty. An in tank fuel pump is designed for the fuel surrounding the pump to keep the pump cool when it is running. If there is almost no fuel in the tank to keep it cool, the fuel pump runs hot, thereby degrading the life and function of the pump. Not to mention the lower the fuel level your pump is taking in the more contaminants from the bottom of the tank it is also tanking in also degrading the life of the fuel pump
I have a 2016 tundra that ishave the issues of a long start. It started back in Nov of 2022! So, i take the truck to dealership & they said it was the starter. 800 dollar's later it was still doing the long start. Then, the weather got warm and the issue just stopped. Then, in Nov 23 it just started again out out of the blue. At this point I have changed the battery, coolant sensor, and the airflow Max sensor. All of these things helped the performance of the vehicle but didn't stop issue! Im gone to try this in my truck and i will report if it works for me! I pray that it works because im tired of fighting this issue!
It has been a real frustration for a lot of us. Mine strted Jan/feb of '23. Went away on its own. Returned the day before Thanksgiving, but hasn't been back after switching to one tank of ethanol free
So, yesterday I stopped at the gas station and got E-85 about a quarter of a tank! This morning it was 28 degrees outside and the truck fired up with so much power! This is the 1st time I have ever put E-85 in normally I get E-87 regular gas! My truck was a flex fuel vehicle until I watched your video. Thanks for sharing the information on your experience. I will let you know how things work as we go!
Thank yousir for sharing!!! I have 2017 e85 teuck and last year dropped some coin on a reflash. It fixed issue and sure enough just like you, hard starts are creeping back. Hope it is not octane specific, for we have 90 octane ethanol free where i am. Any ways, i am at about half tank right now. Will be stopping in to fill up on the way home today. Thanks again sir!!!
Really hope it works. for you
Did this fix your issue.
It seems like it got better but not totally fix. What mean by got better, is it did not hesitate as much before starting. I did use high test gas (93 octane) it was better. As weather got warmer, hesitation went away. I did have the reflash done with toyota when this started. It seemed to have fixed it until winter came back around. So between non ethanol and high test gas, it got better.
one person commented that they just switch to e85 during cold wether, found that interesting
I have this same issue. What I figured out is if I put the key in run for about 5 seconds before I start, it goes first try everytime.
Heard some others say that as well. Supposedly primes the fuel pump
2015 5.7l, and I have the same problem, two winters in a row. I literally have my fuel tank half way out to change the pump as I'm watching this video. Screw that. I'm putting this thing back together and will hit my local ethanol free pump. I will report back in 1 week.
Let me know how this goes for you. I'll be real interested.
@@kedrevs4037 so far no better, I put 22 gallons of ethanol free 89 in it. Still hard starts. I put my odb reader on it and the truck said it's in ethenol mode with alcohol level at 72%. Bummed, but I'll need to get an updated flash at the dealer.
sorry to hear it, definitely a bummer@@addictivecode
Does your scan tool have the capability to reset the ethanol % back to zero
@@brettperkins4643 no, I'm not setup to do that.
Hello KEdRevs! Thank you so much for uploading this video. I'm currently going through the same issue with my 2016 Tundra. Within 3 days, I had my spark plugs and battery changed. I thought I've solved it but No! It happened again. 😢 I'm going to try what you did. I just wanted to confirm you used 87 Ethanol free gas?
That is what I used and no issues for about 6 weeks now
Did it fix your problem? have you experienced a strong gas smell with your issue?
Believe it or not. Yes, it did. I am now back to using regular 87 octane gas due to budget issues and also because it's starting to get warm. I'm crossing my fingers it's not a weather related issue, meaning only during the winter months I can only use ethanol free gas to start the truck.
@@brianflores1446 when u had the issue was there a gas smell after a drive when you parked?
Not that I could remember. I was more annoyed by the fact that the Tundra had an underlying issue like this after 4 years of ownership. The only gas issue I smell is when I do a cold start in the morning, but I didn't really think it was much of a concern.
I'm also hoping to keep truck for at least 300,000 miles. At 60,000 now (2018) so this king 20 years to go!
Haha, I think you should make it.
Mine had this issue but I went the cheaper route. Started using e85 during the winters only. Now i have a pump local to me that carries it so I actually prefer the e85. A whopping 10mpg on 35s but she definitely runs better.
Well that’s interesting!🤔
ha this continued to resolve your issue? when you had your issue did you experience a strong gas smell?
I have had the same problem with my flex fuel 2015 Tundra. Now that it has warmed up, no more long start. But I am sure it will come back in the winter. My question: Since it does eventually start, does the long start hurt the engine or other components in any way? I am trying to decide if I should go to the trouble of buying ethanol free gas next winter. Thank you, loved your video.
One person commented that switching to E85 during winter months fixed their problem. I think it puts some strain on the both the fuel pump and the starter, but if it's just a few times, mostly just seems to be annoying mostly
I’ve got the 18, and didn’t know it was flex until watching this video. I always fill the tank when it gets to half, just because the tank’s so big. I’ll try to find some ethanol free, but haven’t seen it where I live.
IF you notice, they produced a lot fewer flex fuels after '18. Hmmm?
I just replaced my spark plugs, which is recommended at 100k, I’m only about 29k late, seems to have solved the problem, but I will try again early in the morning.
I have a 2017 crewmax 5.7 that started having starting issues in the cold the second winter I had it. When it warmed back up it started fine everyday...as soon as it got cold the truck didnt want to start again. I've been wondering if the little bit that the oil companies changed the ethonal content would affect the ecu like that. Mine is flooding itself out, theres a big blue cloud of fuel rich smoke when mine finally starts. Ive been thinking that a tank of ethonal free gas might be the solution, you may have convinced me to go spend the money on it...Thank You!
hope it works
Did this resolve your problem. I am having the issue as well. Did you experience strong gas smell after completing a drive and parking?
Yes the ethonal free gas fixed it. When its cold out the ECU thinks I have a tank full of E85 when I actually just have regular gas. Not really sure of a permanent fix to this besides having the fuel/alcohol content reprogrammed..that's far beyond my expertise at this time lol
@@ClinesCraftedWoodworking it only smelled like gas when it would first start because it was flooding itself out, after it was running and warmed up it was completely normal
@@FreshCoastProductions thank you sir.
I just started having the same problem ,on my 2011 Tundra ,also smelling like gas.
Never had gas smell. Hope that is a fluke.
Google tundra ethanol density relearn. Lots of posts / walk-through to fix with scan tool.
Same issue here on my 2012 with the gas smell and long start. Have you found a resolution? I have replaced pump twice and have the launch scan tool and have done the reset and relearn of alcohol density (which was only at 2% when i done it) still the issue persist.
Does your truck have an aftermarket remote start? My truck started having this problem on cold days after I installed an aftermarket remote start.
No, no electrical mods at all. Sorry, hope you find a solution.
I had this same problem, and i had a hairline crack in one of the injectors. Replaced injectors and problem hasnt came back in 4 years
Now that is very interesting, thank you
I am having this issue after many attempted countermeasures. Did you experience a strong gas smell with your problem?
@@ClinesCraftedWoodworking yes i did
The longer your truck sits, the longer it takes to crank
@@RG-bu3gz my smell seems to be coming from behind the cab but then again it’s kinda hard to tell for sure. How’d you pin point it to the injector?
Man I just got a 2013 5.7 FFV Tundra and I’ve been back to the dealership I got it from twice because of this issue. Mine sounds exactly like the clip you posted in the beginning of the video. How much ethanol free should I put in to try this? I’m also in Georgia
I ran mine down to about 1/3 tank, then filled with ethanol free. Hope it works for you
So it does work running the ethanol free, but as soon as I filled up with regular e10 again it did it the very next morning again :/ did you experience this after using regular gas again?
Thx
Hope it helps
I only put e85 in my 2010. Never had this issue, but it's good to know.
That’s interesting, what sort of highway mileage do you get on E85 only?
what bed cover is that?
Tyger trifold
@@kedrevs4037 thank you!!
I have a “V” at my fifth digit
Hmmm, 6 cylinder 4.6L 1URFE gets an M at 5th letter, Sure your V isn't a Y
