Cold start issue

I recently purchased a 96 prelude with a H23a1. I apologize for my ignorance, but this is my first honda and being a sbc guy this car constantly has me scratching my head. If I let the car sit for several hours it doe
s not want to start. It will crank for 10 mins or so before turning over. When it does finally turn over it idles extremely rough and sounds as if its misfiring and has no power. After a few mins of rough idle and feathering the gas for a bit everything seems to go back to normal and it runs like a top. Ive replaced cap and rotor, plugs, iacv, and ign.coil, ive also adjusted valves and replaced a broken ground wire to dist. No check engine liggt has come on since i replaced iacv.

Aside from the little "quirks" of the Honda engines/ Preludes, a 4 cylinder is a 4 cylinder, or in your case, a half of a V8! (Fellow SBC & BBB Guy here)

Were you referring to his idleing issue or was that an intended educated stab at American powerplants?

I would have thought it funny and laughed if you had said that it was the other!

Re: Cold start issue

Small Block Chevy. Fair enough.

I'm supposing you mean vintage engines when you say that. So that would mean you diagnose with the trusty ole vacuum gauge.

Well, in this case stick with what you know. It could be a ring issue, or perhaps a valve adjustment issue in which ole faithful will tell ya.

Could be weakened coil or a distributor issue, but I doubt it.
I have to turn on my ignition and wait a few seconds for mine to start. Works everytime.
Turn on key, start to crank right away and she fails to start for a good long time like you describe. Why? Got me. But I turn on the key, wait for the radio to begin playing and fire it up.
My thinking is a fuel pump issue but I haven't pin pointed it yet.

Try that. Who knows, it may work for you too.

This does make logical sense. Cold engine, the worn out rings haven't expanded to cause a good seal making compression squeeze by the rings, making it hard to start. Finally after cranking and the friction between the rings and walls have caused the rings to seal "better" starts making it easier to start.

Sounds like a cold and warm compression test is in your near future.

I do the same thing... I turn the key to RUN, Wait a couple seconds until the "light show" of dash lights go out, and then crank it. I believe that it gives the fuel pump time to re-pressurize the lines and rail (or something like that... As I am JUST speculating) but it cranks right away every time.

Yup you hit the nail on the head with what the problem IS (not enough fuel pressure on start up), now you gotta figure out WHY.
I.E. faulty fuel pressure regulator, fuel pump not holding enough pressure, leak, etc...
