Slow to start 2000 Odyssey

In the morning and typically after it sits for over an hour or so it turns over for 4-5 seconds before it fires. The battery is strong and turns over as fast as it ever has.

It might be worth mentioning that it had the warrantied EGR un-clog job done in November (which Bankston Honda charged me for, but that's another issue). Also, the EGR valve is once again making this strange buzzing sound when idleing while the AC compressor is engaged.

The dealer has only been able to waste my time on this problem. Any tips???

Thanks everyone...

does it turn over slow or does it take long to fire your topic throw up a flag and makes me ask this question. People often say the car cranks slow and it leads one to look into a battery problem when they actually mean that it cranks longer than normal before it starts.

2nd question is what is the level of gas in the car?
hondas are know to have a longer crank time when the tank is near empty just because the fuel takes a while to get up to the fuel rail.

one other angle would be that the immobilizer is reading the chip in the key on the 03-04 there is a considerable start time verses that of the 02-99 because of the new immobilizer system.

There may also be a fuel regulator problem that is the fuel to bleed back into the tank faster than it should.

As far as the EGR buzzing im curious on how it does that. the solenoid that activates the EGR valve is on top of the valve itself but the valve isn't always energized. when it is energized is when you are driving the car not at idle so how you would here it buzz is strange maybe its something else.

It cranks longer. It turns over fast, but takes a good 4-5 seconds (sometimes less) for a cylinder to actually fire. At this point it sputters for another couple seconds until it comes to life...only then can I release the key. Afterwards the motor runs perfect.

As for fuel level, I experience the same problem at various levels - in my flat garage, and at odd angles in parking lots here and there.

As for the EGR, the sound is like a diaphram is vibrating or something. Heck, I could record it for you. : ) The sound went away for a about month after they replaced the first EGR. Then came back identical to as it was before. Again, it is only while the AC compressor is engaged and in park or neutral. If I change the RPM either by pressing the gas pedal, or putting it in gear it goes away...and then immediatly returns when I let off the gas or put it back in park or neutral. More annoying than anything...

Thanks for your help...

That sound like a fuel problem may be the fuel pressure regulater is bleeding down.

Still doesn't make sense to be that may just have been coincedence. The EGR works in the way that there is a solenoid that controls a pin that moves in and out. Its not like the EGR valves years ago that are vacum operated and they do have a diaghram. Sorry not much help its hard to diagnose noises without actually being there to hear it.

I eventually found a Doctor that put me on Tramadol for the pain...which works most of the time. I started using because I had 2 operations on my arm due to a compound fracture. Now I have been taking tramadol for 6 months. Before trying Tramadol I've had fibromyalgia, edgy leg syndrome, cfs, sciatica, and a spinal fusion. This has gone on for more than 7 years now. As far as agony command, it works wonders. With any agony medication, it is best to head the agony off at the pass. Whereas vicodin, etc work fine for acute agony, tramadol has to construct in your scheme, taken on a normal cornerstone, with or without pain. Take care
