Any hints what would cause a hard / long startup?

It feel exactly like I'm not letting my fuel pump prime, but I swear I do.
This morning a made a quick test, flipped to on - waited for pump then tapped the start button for 1/10 a second - waited a few seconds again - and presto it starts on the first crank like magic. Not very scientific... but anything else I should look at? I suppose tomorrow I try it just with the key as see what happens.

This is pretty much how my car starts every time and has since the day I owned it. On my second engine and it's basically the same...

Probably normal,

but there is a minimal chance you have a pinhole leak in the fuel feed line (common leak, search) which would cause your fuel pressure to bleed off and cause long starts. Probably not, but just saying its a possibility.

It's not the fuel pump (sorry Travis), just the nature of the beast. The ECU needs to see a synchronization of the crank and camshaft sensors before firing. This means the engine generally won't fire with just a tenth second push of the button.

Mine is harder to start after I let it sit a day or two. It starts great if I drove it the previous day.

You can check your injectors seals for leaks. After running pull the cover off the fuel rail and visually check for wet spots or has smell. I had the same problem until I changed orings and injector seals. Fixed my problem.
