Hello everyone,
I just replaced my ignition switch on my 2004 accord and now it will not start at all. I even tried it with the old switch. Before all this, it would do a buzzing sound and take a few times to start which lead me to replace the ignition switch. I'm assuming the immobilizer is triggered? Right now I got the batteries disconnected and hoping that will reset it. Any advice is greatly appreciated, thank you!

 

FYI for anyone that searches for this... problem went away... pulled ECM fuse, hit button of the flashing indicator below the steering wheel, and had the negative battery cable disconnected for like 20 minutes. Thanks if anyone did read this!

 

You must of changed the switch while the battery was connected.

 

Im having the exact same issue after replacing the starter and ignition switch but can't find the PCM fuse you are referring to.

Thanks

 

The PCM has a few fuses. #19 fuse in the driver's side fuse box, #23 in the driver's side fuse box, or #13 fuse in the engine bay fuse box.

You can disconnect the battery and this should also accomplish the same thing as pulling a fuse.

 

Thanks for the reply. I disconnected the negative and it will still crank but not start. Not sure if it is the key not being recognized since I changed the ignition switch or the immobilizer got triggered.
