NEED HELP LONG CRANK TO START

What i have is a 2010 trd off v6 d cab. I got the truck last feb, since then i only put 4,000 miles on it. but one time last year and one time last week and today. i went to start the truck and it was cranking forevery. now it does start on the first long turn or the second turn, (its like no gas and then i bit then runs rough) it runs rough for 2 sec then idles great. i drop it off at toyota dealer today and told them keep it for a week and they gave me a camry to drive. any one have this problem as well, i always use a name brand gas pump, and no other problems. any info or items to check will help thanks
only thing installed is a oem trd oil cap and recall gas pedal done (all stock)

 

yeah i have the same problem but im out of warranty so no tsb for but it cranks for a while 1st try then always catches second time but this only happens once in awhile

 

I just started a thread on this today. I've only had mine 5 weeks and it did it several days ago and then today it did it again. Has me worried. Someone said I need to let the fuel pump prime first? WTF? It's a brand new truck.

 

I had a BMW that had this problem and it was a couple of injectors that were bad. After I paid to have the computer test it I realized I could replace all six of them for 50 bucks more than replacing two of the bad injectors plus the test....I got a kiss for that one....

 

Ya mine did it the other day when I was on "E" and I was angled down hill.. just figured it was normal per the circumstances.. i'll let u know if it does it again tho

 

Mine did it for the first time this morning. It might have been because I was low on gas but I havent had this happen with any other vehicle.

I just want consistency. It seems everytime I drive this truck there is something else. Makes me think about how much I am spending in suspension and wheels.

 

I've had my truck for about 2 months now, daily driven, and this has happened on the three of four occasions that I've stalled taking off at a stoplight. It stalls, I turn the ignition to off, turn the key to on, then crank the engine for a few seconds and it won't start. I have to turn the ignition to off again, then crank it over again before it finally catches. This takes what seems like forever when you're already embarrassed about stalling it out in the first place and the people behind you are making angry faces.

I've never had a vehicle do this, and I've owned three manual trans. cars before. Kind of weird, but since it doesn't occur on a normal basis (just when I stall it out), i haven't been worried about it. Still getting used to the various clutch uptake levels and the odd/vague throttle modulation on this truck though.

 

I have noticed somethin similar in my new and old tacos. i notice it only happens in spring or fall when you have winter gas on a warm/hot day or summer gas on a cold day.
OP- this might just be a little more exacerbated since it sounds like you don't run your truck often. If it does it repeatedly then you probably have a problem

Does ethanol go "bad" quicker than real gas?

 

i have had this happen to me on occasion, particularly when it is cold out, just a delayed start however, not much to cause worry, just a mental note. mine is an 08 and if it gets any worse or more persistent i just might have to check out that tsb

 

YEs ethanol does not last in quality as long as "real gas!" Both of my lawnmowers and the service dept agree with that statement....

 

I just had my pressure washer replaced(bough new last april and brought it in in November..JUST got replaced last week). And in October i had to rip apart my quad and clean the caburator. I Talked to a service tech from a Honda dealer, he said there has been numerous problems last summer w. the same issue.. The ethanol breaks down and leave small white deposits(almost like little bb's) they eventually cause everything to clog up and run like shit or not at all. this process can happen in as little as 2 weeks!. for the small engines, run no less than 93 with a few ounces of Sta-Bil Ethanol Treatment.

As for our trucks.. mine does the 'Long Crank' every now and then. Yesterday was the worst, thought maybe cause it was 60 degrees this weekend and then we got 8" of snow yesterday. But our trucks are manufacture to run with ethanol... but if this is a problem.. whats gonna happen when the new law goes into effect using 15% Ethanol rather than 10%?

 

I know this is an old thread but hoping it helps others...so I too had the same issue and it would only be after sitting more than about 7 hrs or over night. I looked all over for help and did the usual, plugs, injector cleaners, air filter , cleaned the MAF, and changed the oil. Before I go further my truck is a 2011 dcsb 4x4 auto with 4.0 with 135k miles and live in the Midwest. So I found one post on TW that made me wonder...these tricks don’t “prime” the fuel pump until the oil pressure gauge reaches a certain amount of pressure then sends a signal to the fuel pump (my wording and not verbatim) hence why I changed the oil thinking the oil was dirty and messing with the oil pressure. Before buying parts I Consulted with a Toyota tech who said also to try the ECT sensor and ultimately the fuel pressure regulator. Luckily for me the ECT sensor was going to be a pain in the arse so I opted for the easier more accessible oil pressure sensor. The following morning my truck fired right up within 2 seconds and the morning after and the day after being at work over 8hrs! Hopefully it stays this way and hope this will help others. Best of luck.

 

Going to file this one away. Keep us posted OP.

 

Do you have the stock fuel pump or a higher flow aftermarket one?

 

Stock fuel pump. Btw not that I think this did anything but I got my hand up in top of the tank and kind of wiggled the plug on the top...I was desperate and tried everything lol. It was doing the long cranks consistently every morning and so far so good. I’ll update if anything changes.

 

Awesome! Glad you got it sorted out

 

thanks.

 

Mine has same issues and thought I had fixed it after replacing the oil pressure sensor, pvc, oil cleaner and fresh oil, new plugs, cleaned MAF sensor...always good for about a week or two after then again. Next will be the ECT sensor the fuel pressure regulator and hope that’s it. I think the reason why it’s always fine after I do something is because I disconnect the ground cable and it resets the computer. Once it’s back to normal it acts up again and never consistent just a pain in the ass. If after the last two things I said I would change don’t work, I’ll just disconnect the ground cable every Sunday for about 15-30 min and get used to it. Oh also every now and then when I shut off my truck and remove the key from the ignition the little oil can light comes on and stays on for Atleast 30 min maybe more. Weird I know and no one knows why. This is my second taco and my 07 never had this issue and it had 283k miles w I traded it. This one is an 11 4x4 6cyl with 137k
