2005 Corolla- Timing chain bad?

[mjoekingz28]

I'll side with the fuel problem.

Only in the morning does my car take a few turns to start. Just turn the key and wait 1-2 seconds then start and voila!

My GF has a 08 corolla with 12K. This car has always taken a few seconds to start from day one. Hot or cold it don't matter.

Interesting.... I'm going to tell her mom to try a different method. Turn the key, then wait a couple of seconds, then start it. We'll see if it makes a difference.

My 2005 corolla did the same thing, took it to the dealership and had the ecm replaced with a new updated ecm and I have not had the problem since. The 2005 and 06 are known for bad ecm,s.

May I ask what that ran you?

I believe the ECU and easy install and programming is around $700. If you have an 05+ the dealer has to install the ECU as they have to enter the VIN due to the immobilizer. The 06s are the most notorious for having [censored] ECUs. Most of the "bad" ECUs were put in vehicles made in the CA plant. I am surprised toyota did not do a recall on them yet, having them [censored] out on you is potentially more dangerous than the sudden unwanted acceleration.

This may be what the mechanic used to make his assertion. Like others, I too would find it odd for a 5 year/100k engine to need a chain ..but stranger things have happened. It would make ignition and fuel pulse timing somewhat out of sync.

Ummm, the 1ZZ-FE was a clean sheet design with NO distributor unlike the 7A-FE it replaced. I'd check the plugs and fuel pressure, as Toyotas are fairly good at letting you know of fuel pump issues before the pump dies.


Ummm, ..well, tell autopartswarehouse about it

..as I said, I don't know the engine.

..but while you're musing this, got a way to easily check the chain that the mechtech alleged was "unright"??

Sticker for the part is 725.01. Many dealers charge 20% over MSRP for parts. Add in an hour or two of labor at $120/hr, if not more?

It was replaced under warrenty so no cost to me. There is a great corolla site called 9thgencorolla.com alot of the users there have had theres replaced and the average comes out to be about $800.00. you should check out the site because of the amout of info on this model corolla also almost everything that can and has gone wrong with this car there is a fix wrote about it on the site. Good luck and feel free to ask me any questions.

Yeah, but shouldn't the ECU be covered by the 10 year 100,000 mile smog equipment warranty?

 

[kevco]

I think the ecu is coverd by a eight year are 80,000 warranty

 

[lui]

there are a couple TSB's that address the extended cranking issue like mentioned before. however i think you are over the warranty coverage by time and mileage. if you want it done you would have to pay for them or just live with it...

but defiantly have the battery checked and tested.

p.s. find a new mechanic
