My wife has a 2000 v6 Honda Accord that starts fine on the 1st trip of the day. After she stops the car at her destination and tries to restart the vehicle it will usually start but runs rough and will die completely when shifted into Drive. After several attemps and 15-20 minutes has passed it will run O.K. The CEL does not come on.
I've seen several other posts from people with the same problem suggesting that it is the EGR valve.
It reminds me of a flooded or vapor locked engine.
It is your main relay under the driver dash..fix it and all your problems will go away. Very simple fix. Not a mechanical problem!!!
I own a 2000 V6 Accord 3.0 and have the same hot start problem. I cleaned the EGR Valve and the port below the upper manifold (which was plugged solid). I also cleaned all carbon from the Idle Control Valve and adjusted all the engines valves. I also cleaned the Throttle Body very thoroughly. It still has the rough idle/dyeing after a hot re-start problem. To solve this, I removed the Thermostat, put it in a pan of water, increased the heat until it finally opened at 200 degrees. A new thermostat for this engine begins opening at around 172 (I checked it also) and so far this has solved the bad start problem.
I now believe the problem was infact related to the engine running too hot. I noticed the temp gauge on the dash was slightly higher recently and the electric cooling fans were staying on for about 10 minutes after I turned off the engine. Hard to believe that a few degrees could cause such total chaos, but I guess the fuel was boiling in the injector rails and actually causing vapor lock.
I did all the fixes, adjustments and cleaning myself which saved me about $1200. My costs were $5 for gasket material, $5 for Blue RTV silicone, $5 for Carb Spray Cleaner, $10 for RedLine Complete Fuel System Cleaner, $15 for a Stant Radiator Cap, $15 for Anti-Freeze, $37 for OEM 167 degree Honda Thermostat and Gasket.
Good luck to you all... Now I'm going to DitnyLan!!!
Need to know what type of EGR valave you have (Negative Backpressure , Positive backpressure , Pulse wWdth Modulated or ported.

I have a 2000 Honda Accord Coupe that on rare occasions will start rough and sometimes stall several times before I can get it to run. The engine is always warm when this happens. It is not a cold start. Any suggerstions?
I had the same problem with my 2000 honda accord v6 and it turns out it was a defect from when it was made. You need to put a fuel injector pump in and a part called the pcm. Honda canada paid for this job to be done on my car, call them if your still having this problem
