Honda Accord 1999 1.8 starting problems

The engine that was put in, was it new, used, or your old one rebuilt. What I am looking for is what of the old engine was transferred to the new engine? Which of the O2 sensors did they replace? Any more or better information would be helpful. When you say it does not start, explain using turnover as the starter engages and turns the engine over and over. Starts is when it catches and run without the starter any more. Clearify it a little. I think we can pinpoint this.

Just based on the information that I read from you, I might consider looking at the ignition switch. They were having some problems back in that general time period.
