Rep Power: 424

Once again, I just don't get it. It doesn't make any damn sense. My car has trouble starting, but it isn't the first start of the morning, nor is it really a cold start. After I drive somewhere, and the car sits for a little while (anywhere from 20 min- 2hrs), it seems to have difficulty starting. The starter cranks, but just won't fire. After 3 or 4 tries, it will stumble, then slooooooowly come to life. Almost seems like theres water in the lines, but I just put new gas in it (so its now happened with 2 tanks of gas from different stations, dumped dry gas in, still no luck. But the gas shouldn't be bad anyways, it hasn't sat for long. I don't think its an ignition issue though, once the car is running, it runs like a top. So WTF????? Once again this car makes no friggin sense!

If you take the key out, then try again does it start? Mine does this occassionally also. But if it doesnt start after a couple of seconds all I do is take the key out and re-insert it, wait the Immobilzer light to go off then it starts right up 99% of the time.

I never tried that... you think the immobilizer is going screwy? What the heck would cause that?

I had to take my car back and get the key replaced because something was screwed up with the chip, don't know if it might be the same thing for you.

I've heard that just the key getting wet affects the immobilizer.

I'm sure you know this, but are you turning the key way too fast? I usually wait for the "maintenance required" light to go out 1st or when I finish hearing the noise (I think it's the fuel sensor thingy) then I turn the car on. My dealer never said to do that, but the dealer where my mom got her Odyssey, they said to do that. And I havent had much problems since.....

I think its Immobilzer related, atleast for my car when it doesnt start normally. When ever it takes longer then normal, the green Immoiblizer light is flashing. I remove the key, wait a few seconds and try again. Usually it starts right up.
