2009 Taco won't start, no codes, cranks

i concur

 

Correct me if I'm wrong but, isn't water on electrical that is in use a big "no no" in general? Infuriating as it is, if that's the case I would think it's on somewhat of an artificially intelligent "self-preservation" mode? I'm far from being an electronic guru though so I apologize for my ignorance on the subject.

Meeting up with a TW member next week, he's been kind enough to offer taking a look at it. Hopefully we can get it resolved then

 

It is and it isn't. I work in a shop at Chrysler so from my stand point, you gotta do what you gotta do. Especially since you have taken this to 2 different dealers who have found nothing wrong and you look like a fool outside in the am with your blow dryer lol.. I'd like to do what I could to get to the bottom of it if I were you.


I myself am no electrical guru either, I absolutely hate it!!! This is just where I would start and if you have access to a air compressor with a blow gun then keep it close by.

 

Difference is if you f**k up and break something you're not the one footing the bill for it. Either the poor customer or the dealership covers it. I've done everything I can within my capabilities.

I do have both of those. I still think water to wiring is a bad idea.

 

Yea your right I don't have to pay the bill but, what do you do when your mudding? or pressure washing the engine bay? When I say "you" I'm not directing it towards you because you, "09_tacoma" may not do either of those things.

I'm 19 and have had 3 trucks in the 3-4 years I've been driving. I had an 01 Ford F-150, 01 GMC Sierra, and now my Tacoma. I took all of them mudding, pressure washed, soaped, degreased, hosed, tire shined, did the whole 9 yards all of their engine bays and never had a problem. The Tacoma I've had in the deepest mud/water and had no problems.

All I'm saying is there is no way I'm going to let anyone tell me that spraying clean water on a few electrical harness on the bottom of your fuse box(that may already be fucked) is going to be any worse then mudding or pressure washing.

At Chrysler we call a fuse box a TIPM(Totally Integrated Power Module) they go bad from time to time so maybe yours is bad. Its either your fuse block, seal on one of the plugs going into the bottom of the block, or you have a loose/bent/broken pin on a plug.

IMO start looking for one of the above.

 

the loose/bent/broken thing makes sense, especially since you have to heat up the fuse box. the heat could case the metal in the pins to expand and just barely make a good enough connection to make it work.

 

thats usually the last thing people check

 

I think ur engine is dead if you can't solve it.... Mind as well go to a junkyard to find another v6.... I have a 09 too.... Knock on wood!

 

I think I may have drawn the wrong conclusion.

After having a blow dryer for an hour to the relays & fuse panel in the dash and zero hints of it wanting to even fire up, I decided to try a heater in the cab. It was a degree below freezing outside. Well after 15 minutes of having the heater on on the floor (drivers side) it fired right up without any issues.

Any new thoughts? I don't know if the heat had finally reached something in the relay box or if the problem originates inside the cab...???

 

This situation is a train wreck. I'm unsubbing from this thread but before I go I just want to say what I would do if this were my truck with this problem.

1. I'd take it to the dealer and make them troubleshoot it with or without codes. Maybe call corporate and give them an earful about the dealer if they're unhelpful.
2. Failing #1 I'd take it to and independent shop and have them analyze the starting circuit.
3. I'd also print all wiring diagrams for the starting circuit and all FSM troubleshooting documents from techinfo.toyota.com.
4. I'd go to work analyzing and testing using a multimeter and find the problem myself. There is a finite number of things that are wrong here and using a systematic approach and process of elimination should reveal what the faulty component is. Use the troubleshooting info in the FSM!!!

Good luck OP.

 

id be inclined to sell the truck. if it were me

 

reading threads like this scare the shit out of me, because if it happend to me id be fucked, i dont have time or money to trouble shoot or anything. that is why i went with toyota this go around. my last car had electrical gremlins and i traded it in with only 12 payments left

im very curous to see the outcome of this

 

If it will not crank, but all the electrical comes on in the dash, pull the steering wheel down toward your leg (straightn the wheel out) and turn the key over. Sometimes my steering wheel locks and wont allow me to crank it, and i do this and it works everytime

 

Sorry I even have to mention this, but zackn291 is making my head hurt. No person with any common sense would spray water up under their fuse box This has to be the most ridiculous thing I have ever heard. Just because you work at Chrysler does not make you an ASE mechanic or an MECP electrician. I have very happy that the OP recognized this is a horrible horrible recommendation. Besides, OP is referring to his INSIDE fuse box which is not sealed at all. The OUTSIDE fuse box I am sure is sealed, and sure spraying a little water wont kill it because it is obviously designed to be weatherproof, but not waterproof.

I hope no one who has this problem goes and dumps water on their fuse box. Some people these days. Thats like telling me to jump into a pool with someone, and then proceed to shoot them with my Taser...

 

did this truck get fixed yet

 

I never said I was an ASE or an Electrician. I wouldnt spray water onto the INSIDE fuse box. As far as I was concerned she was referring to the UNDER HOOD fuse box.

As I said in this thread earlier, spraying water in a mist form at the fuse box under the hood SHOULD not hurt it when you are spraying the SEALED plugs that go into the box. Mud, dirty salty sandy road water, snow, ice can all get splashed at the UNDER HOOD fuse box and not cause any problems then, what is a little bit of clean water out of a spray bottle going to harm? When the plugs SHOULD be sealed. If one is not sealing properly then that very well could be the problem.

 

No it is not.
I've given up on trying to get it figured out for a while and have just been dealing with it. I can't go where I want to go, when I want to go anymore in fear of being left stranded. My mind is completely boggled by the issue, good news is out winters are mostly a dry cold so it'll start a good portion of the time even if temps are below freezing.

 

#1. Try going up the chain of command.

 

Idk how the car side of the industry works but i know that on the motorcycle side of the industry when there is a problem that a tech can not figure out the tech can call a regional technical adviser and they can usually find and find the problem or point them in the right direction. i would call toyota and ask if they they have such a person if so then they are your best bet for figuring out the problem.
