    I purchased my Taco in Dec. Since then there have been about 8 times where the truck has trouble starting. The first time it was a cold night so I just chalked it up to that. Then the next few of times it happened I thought maybe it was the cheap gas (dealer assured me it worked just as well as higher octane gas). So I switched to better gas and since have had it happen 3 more times. I'm not sure if it's the starter, or if it is the fly wheel or something else. Anyone have any idea's?

    I'm a good 200 miles from the nearest Toyota Dealer and since it doesn't happen on every start up I have no idea how long it will take them to diagnose the problem and fix it.

    I have the same problem with my 2011 taco. I've got an incline in my driveway (about 5% - a little over a half inch per foot). I've noticed the starting problems are the worst there. My truck is an automatic, so no clutch/flywheel problems there. My fuel tank was just filled (with premium gas... I can only use 91+ octane with the supercharger). I'm guessing something with the fuel pump? Either of you two figure out what the problem was?

    I have it booked for service in 3 days. I will let you guys know what the dealer said.

    I've noticed my truck has a couple hard starts after I have disconnected, and then reconnected the battery which resets the ECU.

    By resetting the ECU, it forgets the ideal Air/fuel ratio for your truck and area specifically and reverts back to factory spec which tends to run rich causing a hard start. It's gonna take around 500-1000 miles to relearn the ideal A/F ratio so you'll have a handful of hard starts till then.

    My truck is new, with 1000 miles, do you think it could be still learning the ideal fuel ratio?

    Yeah, but it wasn't all that cold this morning. It's been much colder lately and hasn't done it. It seemed to warm up today.

    In all, I've had probably 40 or 50 hard starts. Now that the truck is a little older, it is nowhere near as frequent as when I first purchased it. There was a string where it seemed every other time I started the truck it would be a hard start up. Didn't notice it increase or decrease with different grades of gas.

    Brought it up to the dealer a few times, I've been told that it is not out of the ordinary for Tacomas to have hard starts and since the truck isn't putting out any codes, there probably isn't anything wrong.

    I noticed they usually occur after a long trip. This leads me to believe that it probably was an air to fuel ratio like shoghi suggested. Since I live in at 6200 ft, any time I take a trip I always go down in elevation which is probably throwing off the computer since there is more oxygen at lower elevations.

    With that said, its been at least 5 or 6 months since I've had a hard start.

    This morning was the first time for me, but basically it didn't start the first time. Just cranked over and over. Then i tried immediately after (prob shoulda waited a second) and cranked and then started (pretty rough though)... Then I went and gassed up, and when I turned it on again it started beautifully. So I am not sure if it's the chip or the fuel pump or an actual issue

    I called a service guy at toyota, pretty good guy actually, has a 2011 tacoma too (an 09 before that), and apperantly he is actually on here, but anyways... He said his 09 and 11 have both done that 1 time. Then never again. He told me he couldn't explain in, but not to worry. So I don't know

    how are you linking fuel quality with flywheel or clutch probs?

    when people have a starting issue..either the motor turns over and doesnt fire, or it doesnt turn over. i guess you have the first issue.

    Yeah, I've had it for a month and started it everyday and this is the first time. It may be tough to duplicate.

    My truck Air/fuel is 14.5 at idol and has been for the last 1300 miles now since i bought it brand new. I don't think this is the cause of the problem because I have reset my ecu a few times since I've owned the truck and never have issues starting.

    One thing I did notice with my dads 08 is that he has had this issue and he just slams the key in and starts it right up.. I've told him to put key in, put it to the on position and wait a few seconds, then start it. He never had the issue after that.

    Yeah I'm guilty of putting the key in and starting up, I won't anymore though.

    Your right, it shouldn't matter but it really does matter. You need to prime the injectors before you start them otherwise your not putting enough gas in the motor due to a lack of pressure in the lines.

    My wifes 600F4i won't start for 15-30 seconds unless you let the injectors prime before start up.. My Type-R honda is pretty much the same but its only a few seconds. It's a pressurized system that SHOULD hold enough pressure when its off but doesn't always seem to be the case. I wait till the beeping is done from putting on the key and that's pretty much close enough. Try that and I bet you don't run into any more problems.

    Wow, sorry to hear you owned a Rotary :)

    Both my parents Taco's have this issue. Never tested my 2011 to see if it does.

    My wife's civic si, doesn't have this issue.
    My type-r didn't have this issue till i upgraded the pump/injectors.

    Maybe it's the amount of pressure it needs? anyone know what the PSI is in the lines for fuel on a Tacoma? Not sure what causes it, but I know giving it a few seconds is the fix.
