    Here are the facts:

    Taco barely 1 1/2 month old.
    80 degree daytime temperature today.
    Parked on driveway for only 8 hours.

    Cranked engine twice for about 5 seconds...no start.
    Third time, after about 3-4 second crank it starts. Slightly rough idle that goes away as engine warms up. Drove around the block with no issues. Parked and turned off engine then started up engine with no issues.

    This has never happened before. Anyone else have similar experience? Should I be concerned and what should I do?

    Thanks

    Just once? I wouldn't worry about it. Happens to everyone once in a while.

    Sounds like you just got a teeny bit of water in the fuel or something similar.

    If it becomes chronic though you have a problem.

    Try using another key that came with the truck. A lot of issues have to do with the anti theft system.

    My 07 4.0 went through a period like that between 30,000-50,000 miles it would produce long crank times. I currently have 102,000 and it hasn,t done it for a real long time. I had a Ford Ranger before this it was an 04 and from day 1 that truck would have long cranks and alot of false starts 1st attempt. The dealer told me they never seen it before and had no cure for it. they replaced a few things and I got sick of going back and just lived with it.

    My 2011 DCLB has experienced three similar hard starts regardless of weather conditions. Mileage is only 2500 miles. Had to two different dealers, neither of whom could replicate the problem (of course). No codes displayed or pending.

    Thanks to TW, i have lerned to set the key to the RUN position briefly before actually cranking the starter... That seems to avoid the problem altogether.

    I know the 09's and earlier had a TSB on the issue calling for a computer firmware flash, but I haven't seen anything about the bulletin being extended to our newer model years.

    Damn, my 2012 starts up a lot faster than the 2008 I used to drive. I hope I don't run into this problem in the future

    My 2012 takes a few cranks to start as well. Tomorrow I plan on adding a red container of "Heet" to the fuel to see if there was any water in the fuel system. Don't use the yellow containers as that stuff is garbage.
    One other thought is to turn the key on for a couple of seconds to pressurize the fuel system before cranking.

    Well everyone, it's a common problem i think with all the years from 05 up (V6) There are a bunch of threads of people mentioning starting taking too long. You would think by now this issue would of been addressed and fixed. I even have an upgraded fuel pump and I still have instances where it takes a while to start.

    If you can hear the starter cranking, is it still the anti-theft system or transmission interlock at fault?

    I'm on my third second gen taco (05 09 12) and they have all done this. Usually in winter. It's a minor problem - if you've ever frozen your ass off at 20 below while hosing down a carburetor with starting fluid, you know what I mean.

    Anyway, with my 2012 and the new Scangauge, I am keeping better track of my mileage - meaning I am keeping better track of where I get my fuel.

    I usually fuel at the Exxon station down the street - but my wife sometimes gets discounts on gas from a BP near here and so I go there - about once a month. Now, there isn't a noticeable difference in mileage or performance, but the only times I have had trouble starting has been shortly after filling up at BP.

    The longer crank times are related to the etanol content in the fuel. This is most noticed on warm/hot days or after a long drive. The location of the fuel rails allow for "hot soak" problems, essentially a small vapor lock. This problem occurs in other vehicles as well. Our fuel is supposed to have no more than 5% ethanol content. I have had the same problem on my '11. Last summer it was happening frequently so I took some fuel samples and recorded etanol levels as high as 10%. ( mileage was in the toilet too). Changed fuel brands for a while, no more problems. The wife's Acura has the same problem.
    Long story, short answer....its our overpriced, stitty fuel. Highly irritating but not much you can do about it.

    Dumped a container of red "HEET" in the tank when I filled her up. The slow starting has slowly disappeared. This makes me think somehow the trucks pick up a little water in the fuel system at some point in the assembly.

    Water will never leave the fuel system unless you can mix it with alcohol (HEET) which then allows the mixture to be burned. Water, being heavier than gas will sink to the bottom of the tank as well.

    Try it, for a couple of bucks it could be a cheap fix. But if you are in an area selling ethanol doubt it would help any.
