Re: Changed head, now car wont start?
If it isn't the timing, you've most likely broken something like a sensor while you were taking everything apart or putting everything back together, or you've damaged something in the harness. There really isn't much of anything on the head itself, so if you're having a problem (that isn't timing) you would have had to damage something somewhere else.
I've never dealt with that specific engine, but the only sensors that could affect anything that are often mounted to the head are the coolant temp sensor and the cam position sensor, and many engines have those mounted somewhere else. That's why I think it's likely that any part failure would be located somewhere else.

Re: Changed head, now car wont start?
This is the third time I have to take it apart though. I should have had the original head checked, but I didnt, hence the reason for the new head.
now I'm generalizing, but all you should really have to do is loosen the tensioner and take off the timing belt and valve cover.
most valve trains have a way to lock them into place: honda's actually have a little hole in the 1st set of cam bearings which correlates to a whole in the cam....which also happens to be TDC!
Engineers did some of these things to make it easier for the little guy (you and me). check on your crank to find TDC and crank it over till the notches, arrows, lines etc match, then go from there.
Good luck, I'm very interested to hear what happens.

Reset the ECU, so any stored parameters are erased and relearned.. What else did you change during the process of figuring out what was wrong?

Re: Changed head, now car wont start?
how would i go about re-setting it? its not throwing any CEL codes as of right now...and I only changed the head gasket, head, water pump, timing belt, radiator and thermostat. a few gaskets here and there, but as far as the engine goes, thats about it.
