Default 05 Accord won't start. Turn key, everything lights up. Confirmed it's not starter, plugs, fuses or..

...wires. Help? My wife and I have owned the car for 4 years. Not one problem to date. The battery was replaced last year as it currently has a full charge. We moved from VA to MD recently and took the car to Fitzgerald Auto Mall in Frederick MD for a MD state inspection as required by the state. Of course we couldn't leave without them trying to upsell us. They failed the car because the rear brake pads were too thin and the back right-rear tire was too worn. As they were quick to offer to charge and fix, we declined as we do most of the work ourselves. We then took the car over to Pep Boys for two new tires. While there, we purchased brake parts for the needed rear repair.

My wife got in the car when it was finished getting 2 new tires, and drove it home. After 20 minutes in the driveway, I had put on some warmer clothes to do a rear brake job. As I got in the car, I turned the key and nothing. All the lights on the dash came on like normal, but the engine wouldn't crank at all. I have tested the starter, plugs, fuses, and wires. I also checked the fuel filter and pump and all are working fine. I believe I have narrowed my problem down to the Immobilizer.

Is this indeed the problem or is there something else I am missing? What is really bothering me is that for the longest time, there was nothing wrong but as soon as other get there hands on it, we have problems!!! Please help!

Also, Jimmy C, I did double check the battery terminals cables and they are all tight and sitting on the battery terminal leads securely.

Thanks Jimmy C and Honda Tech...

Jimmy C:

I have previously checked the battery and battery cables as there is no corrosion at either end of each terminal.

Honda Tech:

Accroding to the owners manual and as you said, the green key icon on the instrument panel is supposed to blink upon start-up (placing key position to "ON II") and the go away assuming you have a properly coded key, which my car does indeed do. Therefore, I'd have to agree that there's more to it than the immobilizer system. As far as exactness is concerned, I insert the key to "ON II" and then continue to turn to "START III." Obviously this is when the car should start its starter-motor to then ignite the engine. When the key is in the "START III" position, there is absolutely no noise coming from the car... no clicking (like a dead starter or battery), no noise what-so-ever. There are no abnormal lights on the instrument panel nor is the "Check Engine Light" illuminated.

it sounds like the starter relay, but before you do that, check the battery terminal tightness, they could have come loose or have a bit of corrosion, it's usually the simplest thing that breaks.

Check the green key icon on the dashboard . When u first turn the ignition switch the light flashes, if the light keeps flashing and it does not turn off u might have a problem with the immobilizer system... Now it suppose to crank and crank but it will not start, that's what the immobilizer system does. If u turn the key and it doesn't even crank or if u hear like a clicking noise your problem might somewhere other than the immobilizer system. Make sure that the battery cables and the battery are making good contact and that they are working properly. I don't know any known issues or bulletins for that starting system on that model. Get somebody to turn the key while you hit the starter motor ( in case u hear noise ,not if the light keeps flashing) that works for me.. Good luck and I hope it helps.

Hello! U said u tested the starter motor ,on the black/yellow wire do u have power when turning the key to the cranking position? That is going to help a lot. The starter gets ground from the bolts to the tranny. The starter 12 volts power from the battery and the starting signal comes on that black/yellow wire. U have 2 wires at the starter ;the big one with a 12mm nut from the battery and the black/yellow wire which is the starting signal to solenoid. When u turn the key to the start position if u have 12 volts at that black/yellow wire the starter needs to be replaced. If u don't have any power going to that wire than your problem might be on the neutral switch or the fuse box or if u have a aftermarket alarm or somewhere in between the switch and the starter. If your accord is a V6 Honda had a recall for the fuse box. I had one in the shop one time that when we did the recall we left one of the connectors loose ,and that can cause that no start condition. Again I hope it helps , Good luck!

Thumbs up Re: 05 Accord won't start. Turn key, everything lights up. Confirmed it's not starter, plugs, fuses

Hi Dear DAN;
As what Jimmy C just said, but I'll add to that :

If you car has automatic gear :

Make sure that; the gear shift stick is in the N or P position

It will Never start if the gear shift stick isn't in the N or P position.

You must hear starter pinion gear clicking while U turn switch to start.

If starter pinion gear clicking, but NO response maybe the flywheel ((( ring gear ) one or more teath broken .

The other possibility : is may be the starter 80A relay burned out,
If U open the fuse box U'll see in its cover lables showing U the position of the relay & its value {{{ Amper rating }}}.

Don't forget to make sure the fuel pump delivers fuel.

I hope that: I add something right & interesting to UR thread.

By the way this is my first thread, I were searching the net to find an answer for one of my audience in an Arab Forum;

The web leads me to this interesting Forum and your thread was interesting to me.

Best regards;

Is the car in park, try wiggling the shifter a lil while holding key in crank position. Is it a manual trans, did you push the clutch pedal all the way down? Does it have an aftermarket alarm, could be malfunctioning.
