08 won't start after reconnecting battery

She fixed it herself?

There is no needing to be a hero here, nor is there any attempt at being one. I am attempting to get to the fact that there may be a deeper root issue occuring here. Especially if she had to give it gas. If you don't want to read it, then don't, that's pretty cut and dry to me.

Other than that, if she chooses to leave it be for now, then great, I'm just talking to her and two other members here about it all. At no point did I mention you, tag you or ask for your opinion. Nor am I stirring the pot at all. Shall I send you an extra strength bottle of chill pills?

 

In all honesty, I'm wondering if a body ground got dislodged when battery was disconnected. That is my GUESS.

In any multi component system, the electrical component will always be the weakest link.

She had a hard start after doing work on here truck. Okay, what can cause that? Yes there will be an ECU reset if the battery was disconnected. The engine should run normally within a few SECONDS. If its not running smooth, then we need to look at what was changed during the work.

There should never be a situation where the gas pedal needs pressed to start our trucks.

160K is not a lot of miles for these trucks. The bad pump suggesting is good, but there are many Cheap things to check first. Changing the pump is a pain in the ass and they are quite reliable.

You guys need to take a step back and let the OP give us more info. I love a good mystery as well, but lets not get pissy with each other.

 

Hmm I haven't heard of this causing issues. I have had 2 Tacomas with over 230,000 combined miles, hard miles in rough conditions. I have been on this site for 8 years and have never heard of this being an problem. Do you feel she needs to replace it because of the difficulties she encountered trying to restart her truck? I will have to research this more.

 

* * Wow, just wow.

 

All I'm saying is that she should be aware that she MAY have a larger issue at hand and should either check it out or get it checked out to make sure she doesn't end up in the same boat as I did that night.

These were the exact symptoms I was encountering maybe 30,000 or more miles before mine failed. Mine failed at 50K if I remember correctly. I also encountered a ton of knocking and pinging at acceleration.

Now it is also possible that at mid point or some point in the 2nd gen years they changed the fuel pump supplier, or design, or may have opted for a smaller one. We live in a society where going smaller is in, manufacturers want to try to cram so much into a package and reduce it's size simply to say it is good tech and "look how far we have come." That's not always a good thing you know?

I see it's not a common issue on the site for sure, as I have been frequenting since 2012 when I bought mine, but it is an issue that I'm sure many don't know about simply because they don't take a fuel pressure tester just for fun and monitor it all at cranking, idle, and as they drive. I'll tell you first hand that a fuel pump was the last thing I would had wanted to mod, and replace on this truck. It was the last thing I would had expected to die on it also.

 

I don't understand where all this anger came from in the first place myself. What, simply because me and another member disagree, suddenly people want to start acting like utter buffoons? It's beyond me bud. Lol.

 

I am sorry to hear you had the issue, but it seems to me that you are contradicting a 40 year toyota tech and advising a new user to replace a part because of an issue you had once, on a different year model? I am glad you are contributing and helping out new users, though. Thx

 

I have no issue with incorrect suggestion being offered. Often they cause other members to think along alternate avenues to come up with a better or correct answer. If the disproving an inappropriate response gets a person closer to ending their problem, then I consider that a big win. Just do us all a favor, include data with your theory. It is raw information, after all.

Obviously, some are better than others at expressing themselves or are on a phone and in depth responses are difficult. I suck at responses on my phone.

No one wants to be wrong and everyone want to be the hero. I think that's pretty normal.

Collective knowledge on these sites is enormous. You get enough monkeys banging away at a key board and the answer will eventually present itself.

Would be interesting now with all the comments to see if she could replicate
the problem by disconnecting the cables and letting it sit the approx. time
it took her too do bearing then reconnect and without pressing throttle and see
if it will start.
I am not agreeing it is a fuel pump issue but I used to work on Chrysler/Dodges for almost
11 years and had many vehicles crank and not start. Crawl under vehicle and smack the fuel tank
and a good majority of the time it would start. Problem is too many people like to run the tank
way to low on fuel and the pump starts running hot and eventually fails. Is why I never let mine get below 1/4
if I can help it. Fuel keeps the pump cool. Just an opinion

 

My blue taco is a 2008, 4 cly standard, 4x4, 2nd gen. All in all, yes it more then likely needs new plugs, I'm sure with the mileage that is on it, it is time. However, I didn't have time to check my records to see when I'd changed them last. After my idle settles back down I will address that issue. My throttle body and everything else under the hood is cleaned and routinely checked. Plugs have taken a back seat to a wheel bearing issue that had became a priority.
When I disconnected the battery I clamped both terminal together, I have learnt over the years that this clears the computer. Yes everything has to be reset, I don't care to reset my stereo and clock, so not a big deal. After reconnecting the battery, it TRIED to start. It sounded like it needed gas but knowing that it shouldn't; I over looked it. Tried three more times disconnecting and reconnecting, same thing each time. Let me add after reconnecting I'd wait 15 mins before trying to start and turned the key on for 1 min prior to turning the key over completely. And no I didn't jump it, everything was working and it was trying to start, no need for a jump. As a last ditch effort I tried one more time, this time giving it gas when it sounded like it needed a kick and it turned right over. It's running. Yes the idle is rough but that has always been an issue in the past (after disconnects) and after a few trips to work and back home it works it's self out. BEST thing is there is no loud hum from the bearing. happy happy happy.

again, thanks to all for their input!!!

 

Good job, welcome to TW!

 

x2

 

great to hear it's all working out! i also have an access cab 2.7 but with automatic, what a great truck. welcome to tw hope all goes well post us a pic

 

I'm wondering if that 60 second key on, but no start, was flooding the intake?

It only takes 2 seconds to pressurise the fuel system. You don't need to wait a full minute.

Any chance there was the smell of gasoline when it started?

 

The way the fuel pump function works on these is as soon as the STA signal is sent from the PCM to crank the engine the pump begins pressurizing the system and fuel delivery begins. The pumps do not run before the engine is started at Key On Engine Off on these trucks as they traditionally do on many other makes and models. The only way flooding could occur is if she has a leaking fuel injector or something but without actually looking at it, it's all spitball ideas honestly.

Flooding is always possibility, however.

 

Tom0662, NO she is not interesting in replicating the problem. LOL!!! I don't have 2 extra days this month.
12TRDTacoma, she fixed it herself!! No question mark. She did take the bearing and hub and have them pressed out though.

 

I meant the no start issue not the hub thing. Good fix though, and to you, welcome to TW!

 

koditten, no smell of gas. I am almost certain it needs new plugs, with the amount of miles I put on it weekly I don't get a year out of them.

 

do you have the dark blue or bright blue? any mods?
