Help! I have a 2006 honda accord EXL V-6 3.0. The car wont start, it cranks but no start. The green immobilizer key on the dash is flashing. I have no spark or fuel. i have changed out the fuel relay and the bat, but no joy. also when i turn the key i hear i buzzing sound from the main fuse box area. i'm wondering if the immobilizer has a relay? i have talked to honda dealer and they want to see the car, now the closest honda dealer to me is 53 miles away... if any can help me out that would be wonderful.. Thanks

 

Have you tried a different key?

 

yes i have. but no joy..

 

That key flashing means that something is up with the immobilizer system on your car. Just looking at my 05 TSX wiring, it looks like there are just fuses on that system. You may want to check the fuses.

The other thing to check is that all ends of both battery cables are clean and tight.

Other than that, you have to diagnose using the Honda Scanner tool, which is only available at a dealership.
