My '08 DC Sport is the same way. Its been cold here (15 F) so that may have something to do with it.
Hard starting Taco??
I have an 08 Dbl Cab, 4x4, TRD etc. I have noticed that it takes quite a few more engine revolutions to start than my prior trucks, some of which were Toyos, some Ford, a GMC. At times it sputters just a little and you have to restart. It has never not started----just seems the starter runs longer before it fires than any vehicle I have ever owned. Haven't asked my sales dealer anything about it yet. After all, they had "never heard" of the TSB on rear springs. Yeah---right!! Anyone else notice thier Taco being a hard or long start???

Others have commented in the past that it does crank a little slower than you'd expect. Far as I know, it's normal. Except for those with a problem where it cranks for a long time and may not start (there's a TSB for this), it's normal. On average, I hear 5 cranks when starting. Never more than that.

Same here whether its -1 degrees like today or its 50 degrees. I am glad you asked the question as I was going to call the dealer today.
our v6 starter cranks, the ecu checks parameters, then provides a spark. I'm no expert, but I read it on the internet, so it must be true. with any luck, someone that really knows will call me on it and expose me as a jackass. :lol:
my truck is at the stealership now getting the rear spring TBS and they are putting on , the 5100s i had shipped to me . i asked them to check the TSB EG011-07 no start condition " revised " , it reads that on first attempt " one key cycle " no injector pulse , after that it will start. look under the hood and right hand top corner theres a tag with any TBS # or authorized mods or reflash to the ECM module.
I typically hear about 3 cranks before the motor starts up. Keep in mind that all batteries get weaker when cold. So, if its below freezing, expect a little harder start. Especially if its below zero.
Glad you asked this question... I have the same concerns...
All other cars I have start faster than the Taco?
I'm in California and it hasn't been lower than 45 degrees in the morning.

I have noticed this also. But I think I might need the TSB done, because the other day I was at the gas station, filled up the tank, put the key in the ignition and it just cranked and cranked, didn't start, so I pulled the key out and put it back in and it fired right up. I think I might schedule an appointment to have it done, and maybe try and get the dealer to do the rear suspension tsb done at the same time.
Same way with the i4. All my prior vehicles have started with a quick bump of the key. This one turns over 2-3 times before starting, and it's a bit annoying actually. Makes me wonder how long the starter will last doing all that extra cranking.
On really cold days, turn your headlights on for 10 or so seconds before cranking it over. headlights are the closest thing to a short circuit on the truck and that will warm up the battery.I typically hear about 3 cranks before the motor starts up.

Headlights warming up a battery? Because their close to a short circuit?
I've started my truck in temps as low as -60 with the truck plugged in, and as cold as -30 without being plugged in. Never had any problems as far as the battery goes. Turning on your lights, radio and whatever else is only going to make the problem worse. The last thing you want is to have all that power draining on the initial start up.

Batteries produce electricity through a chemical reaction. Chemical reactions work better when they are warm. Believe me, it works.

Awesome. I studied electronics in HS too... I have worked on F-16's and F-22's for the past 7 years, a good portion of which I had to deal with wiring. I've also lived in Alaska for the past 7 years dealing with starting my vehicle all the way down to -65 without windchill. So perhaps I know something of which I speak.Batteries produce electricity through a chemical reaction. Chemical reactions work better when they are warm. Believe me, it works.

Now that we have our jobs taken care of...10 seconds is not going to warm the battery up enough to make a difference that is noticeable to the driver (or the vehicle for that matter) when it comes to starting. Give me some internal battery temps before and after, showing a change over 10 seconds of headlight use and I'll retract my statement. Anything less than a 1 degree difference is useless.
In cold weather you need all the AMPS you can get out of that battery to get the vehicle to start. Having the headlights on isn't going to help.
You know where I can find a battery with an internal thermocouple for me to connect to?
As you stated in your previous post, your truck is plugged in, a block heater I presume. Leave it unplugged for a night and try it, you got nothing to lose. Just remember to turn the headlights off before you start the truck.
Having a warm engine block, keeps the metals from contracting as much, lessening the extra friction that the starter motor needs to overcome to spin the motor. Less friction= less torque needed= less current needed.
As I stated earlier, batteries produce electricity through a chemical reaction. Chemical reactions work better when warm. A resistive load will heat the battery up faster than an inductive load will.
BTW where do they put the batteries in a F-16 or a F-22? I hope it's not classified.

The F-16's is in a wheel well and the F-22 I don't like to talk about on public forms. Just know that it's pretty sweet.:naughty:
I've started my truck both plugged in, and unplugged. I have a battery blanket/warmer on the battery to keep it warm during those really cold nights. Never heard of the headlight thing until now, but it seems that the general consensis of people is that it's a myth. I've searched the different forums, and haven't found one person that can give proof that it works, other than "seat of their pants".
I understand that batteries work by chemical reactions, and I understand that in turn creates heat. But, my argument is, that 10 seconds isn't going to be enough time to warm the battery any signifigant amount. Wouldn't you want to have the most energy going to the starter to get the truck to turn over? Why would you have your headlights on, taking away power from the starter? Unless someone can somehow take an internal temp of the battery before and after, I'm not going to buy into it.

Mine is brand new...only 185 miles on it. It does the exact same thing. I thought I noticed it on other ones as well when I was test driving them from dealer to dealer. My Dakota would turn over as soon as I turned the key forward. I'm just gonna let it be and take it as a Tacoma thing now that I know others have the same thing going on! :lol:I have an 08 Dbl Cab, 4x4, TRD etc. I have noticed that it takes quite a few more engine revolutions to start than my prior trucks, some of which were Toyos, some Ford, a GMC.

I've got the same exact problem, I thought it was just my truck. Is there a TSB out for this?Mine is brand new...only 185 miles on it. It does the exact same thing.

You don't want to leave the headlights on when starting. My bad for not making that clear in my first post. I found this, check it out http://www.startribune.com/business/15370726.html
On a lighter note, If I had to go out when it's -65 I'd be changing my name to Ken, because I'd feel like a damn Ken doll....anatomically incorrect! LOL

Hey everyone-
Brand new Tacoma owner here but this is something I've run into in the past. I was once told that the Tacoma ECU had to "see" the #1 piston at top dead center (TDC) before it would allow the engine to start. I never bothered to look into if this was true or not but if so it would explain the extended crank times.
