The engine will not start on the first crank in the morning. It usually takes a second or third try. After that it has no problems during the day even if it sits for hours before another start. I have turned the key to the on/run position for a few seconds to turn on the fuel pump and it still does the same thing. I have done this several times in a row before trying to start the engine and it still requires at least one crank before startiing on the second time. I have replaced the plugs, rotor and distributor cap and idle control valve, cleaned throttle body too.

You could have a vacuum leak somewhere, allowing too much air for the fuel. That is what I would look for, since you've done all the other items.

It appears to have been a fuel pump. Replacing it seems to have solved the problem.
