Re: 00 Odyssey will start, then not start! NEWBIE need help!
Well, since the issue is intermittent, it may be a pain to nail down.
Somehow you need to figure out if this is a fuel delivery problem or a spark problem. When it does not start, does it kick at all like it's trying, or just cranking away? Also, do you smell fuel near the tailpipe when you've been cranking it but it doesn't start? This and any other symptoms might help.
On older Hondas, there was a relay up under the dash that turned on the fuel pump when you were starting and running the engine. It would go bad such that when the interior of the car got hot, the relay would not close and the car would just crank and crank. When the car cooled off (or you open the door for awhile) the solder joints inside the relay would connect again and the engine would run perfectly. You can search the internet for Honda main relay and get all kinds of hits about it.
However, I thought Honda fixed that in the mid-90s. However, it might be a possibility, especially if you cannot hear the fuel pump run when your turn the ignition to "on" when the car is in it's "no start" mood.
Other possibilities...if the engine compartment gets very hot, you can vapor the injector rails, especially if the fuel pressure regulator is not working right. However, that would probably cause some performance loss when you are accelerating hard. So, if the car runs pretty good and has a lot of pep, it is probably not the cause.
The bottom line is that you really need to be able to check fuel pressure and spark right when it is not starting. If you wait for the mechanic, it may not do it!
On the transmission, you can talk with them and see if you qualify for the extended coverage. Worth a try, but ask before they work on it so they don't tell you they won't cover it AFTER they've already worked on it.....
Hope this helps....perhaps you can give more symptoms and I and other can help out.....Glen
