You mean it actually starts then dies? I'm not an expert but that sounds like bad ground somewhere? It doesn't sound like fuse as blown fuse will probably prevent you from even starting the car.

Whatever you do, don't pay the installer!!!!!

There's no telling what he screwed with, but even if he was an amateur at this there's nothing he should have touched in regard to stereo equipment wiring that would have an effect on the car stalling after you start it.

I would advise you not to pay him. And then get his full home address and phone number.

Then call a tow truck and have it towed to your Honda dealer.

Have them check everything out.

And make your installer pay the bill.

Immobilizer maybe? I do not know how but he could have messed the wire up some how or something.

When it dies do the lights on the dash stay on? Or do they turn off?

Sounds like something is wrong with the immobilizer. I don't know how/why a stereo install would mess with the electrical systems involved with the car starting, however, you need to re-link the keys to the immobilizer (have them reprogrammed).

here is the guide he looked at for the steering wheel control: http://www.pac-audio.com/swixprogra...mmSearch=Honda&Submit2=Search+Vehicles&ID=414


would that have anything to do witht eh car stalling issue?

That is what i would do, but isn't there a light that blinks in a shape of the key if immobilizer does not recognize it?

how about steering wheel control? would that effect the car stalling?

Okay, to help you out here you need to be very specific:

When you start the car, for the time it runs does run smoothly? Do all of the malfunction indicators in your instrument panel go out? If not, which ones stay illuminated?

When the car stalls, which if any malfunction indicators come on the IP? Does the tach drop to 0 or does the needle freeze in position?

Does the accessory mode still operate (can you roll your windows down and up, turn on the HVAC fan, etc.)?

If the acc mode is still operating, try turning the radio on and off. Does it work?

If you turn the ignition off completely and just turn it to acc without starting the engine, will it stay in acc mode?

If there was a problem with the immobilizer there would certainly be the flashing green key indicator at the top left of the IP.

Right now I'm ruling the immobilizer out because the car does start.

AFAIK, the ECU will always allow a properly cut key to start the engine, but it will then immediately shut down the engine a few seconds later if the ECU is not happy with that key's RFID code or if the immobilizer is not working.

In other words, your symptom is quite likely caused by a problem with the immobilizer.

Examine the wiring harnesses, at the ECU. Since your installer was working on a navigation unit, he had to tap into the vehicle's speed sensor. It is possible he did not know which wire was for the VSS, and in the process of locating it, damaged the ECU harness.

This seems very plausible.

Listen I think it may be the immobilizer when you crank the car is the little green key light (immobilizer) blinking as your car is cranking if so your keys need to be reprogrammed to the ecu or he hacked in to your immobilzer installing w.e he did n damaged something

Would trying his other keys work to see if it is the key?

Aren't the 2003+ Accords using a Type 4 immobilizer that uses a rolling code program, or is there a Type 5 now; lol?

No if he had other keys it would do the same thing the immboilizer it self lost programming and not regonizing the key cauae the lost programing. and no the immbolizer still the same main thing it just lost it programing. Get it reprogram by the dealer scan tool
