Air leak in fuel system?

I have an older car with fuel injection. If it gets parked with the front
end higher than the rear for any length of time, you have to crank it for at
least five minutes, even if you move it to a flat place or with the rear end
higher, before it'll start. When you start cranking it doesn't fire at all,
then fires intermittently a pop every few revs, then gradually more and more
firings until it can run on its own. (of course I don't crank for five
minutes continuously or the starter would overheat.)

I'm guessing there's a slight air leak in the fuel system? Or is it
something else?

first check that the pump runs at turn on, then check how much pressure
there is, then check that it is rich enough to start, a whiff of carb
cleaner in the air intake will show if it is not rich enough.

It sounds like there is a lack of richness and that warming the engine (and
getting lots of neat fuel in the cylinders) by lots of cranking brings it up
to a state where it can stumble into life.
