All fuel injectors bad?!

What was the diagnosis?
Those codes and symptoms point to bad injector driver in the ECM.

 

They replaced a fuel injector set, air surge gasket and intake manifold gasket.....

 

Wow ,all these in a new truck.

 

I hope for OPs sake I am wrong, but I dont think all that needed changed and the problem may not be resolved completely.

 

Pretty much what I was thinking.

 

Your results will vary depending on who worked on the truck, a mechanic or a parts changer.

 

I don’t get all the critique going on here now as to how the OP problem was address by the dealer and TOYOTA.

Damned if you do damned if you don’t geez!!

More than likely they found one faulty injector and a leaking gasket and wisely decided that being a new vehicle, the best approach to avoid a re-occurrence of the issue was by replacing all the associated components in the system, and turn the chapter on the story.

Moreover, it’s a lot cheaper labor wise to replace the components at once while everything’s already in state of disassembly, rather than risk another component failure occurrence in the associated system(s)

Cheers!

 

Best response here.

You see... Here is the problem with why everyone hates dealers. From tech to the person on the phone, there's probably 5 people involved. If you want to know the absolute knowledge of what's done, talk to the tech!

 

and just had my oil changed at the dealer and there was oil all over the frame and shield and I thought, man why don't you guys wipe it off?, some people just don't take pride in anything they do...

 

Rust proofing! Either that or you have no oil left in the pan..

 

And of course on the https://www.toptiergas.com/ website where “Vehicle and equipment manufacturers write and enforce the standards”.

 

Although it wasn’t written on my repair invoice, the service writer hinted there was indeed a “leak of some sort” and that was why the 6 direct injectors and 2 gaskets were replaced. Drove it home yesterday (a good 35 miles) and it ran fine. Happy to have it back. Just still confused as to why it happened other than a component failure.....
Thanks all for your comments and opinions....

 

I don't think you did anything wrong or operated the vehicle in any way that would cause a problem.
I do short trips or multiple errands all the time with no issues.

If they would have just replaced one injector and a few days or months later another one went out, it would cost many expensive labor hrs to do the job again. And lets not mention they need to get you another vehicle at their expense or the inconvenience it puts on you. And some companies do care about their reputation and your satisfaction.

Glad it all worked out for you

Cheers!

 

Well, 3 thousand miles later the same thing happened.... truck died in the middle of the road, restart but only sorta runs if you keep feathering the gas pedal.... towed to the dealership... very bummed. Have owned many Toyota vehicles over the last 40 years and never had one towed let alone have to have any major repairs.....

 

I have to say that I would also look at the MAF. Those things really mess stuff up. I’ve also had a coolant temp sensor on the 3.4 engine do similar things you are saying. Everything has a sensor that the ECU uses to run the world. A bad sensor in many areas can really screw up. Good luck.

 

When it did this in Jan they had it for 4 days trying to figure it out. Determined some kind of gasket failure caused injectors to leak down and replaced 6 injectors and the gasket.....

 

The dealership has had my truck for 2 days and now they say they cannot duplicat the problem!? Check engine and Trac Off lights were staying on, surely it would have given them a code? I’ve driven a lot of Toyota vehicles over the last 40 years and never had to have one towed for repair.... This one twice in 3000 miles... confidence shaker....

 

hey op I had a similar problem with a gmc sierra. No codes, they couldnt figure it out, ended up replacing the left half of the injectors and the problem went away.

 

well this is a strange problem, I would buy an extended warranty just in case. Im not a huge toyota fanboy, but I would try to get this problem fixed with them and after its fixed Id doubt you have any more. serious repairs or not.

Ive had wierd problems liek this with other trucks (diesel) and I had a truck in the shop for 4 months we couldnt figure it out. Eventually was just a few sensors and havent had a problem since.

Sounds like sensor or something at this point, unless they didnt fix the leak correctly last time and the injectors are all bad again but they dont want to admit it.

I would find it very strange after leaving you stranded it would all of a sudden work fine.

 

They did that in Jan when I had this problem the first time.... not sure if it was left or right side, but they replaced 6 injectors and the gasket.... (@30,000 miles.....)
