Lately, sometimes it starts right up, but about half the time I find
myself giving the gas pedal a couple pumps to make the engine turn
over. those times, even though i haven't done anything different, the
engine won't start unless i feed it some additional gas by pumping the
gas pedal about twice.

it's odd to me in that rather than starting becoming hard all the time
or just impossible, it's unpredictable.

does it sound like starter problem? something else? thks in advance

This makes no sense. Pumping the accelerator with the engine not
running does absolutely nothing. Back in the days of carburators,
this actuated the accelerator pump circuit in the carb, literally
giving it a coupe shots of gas. The fuel injection computer will
simply ignore you. If you are talking about pumping the pedal while
cranking the engine in order to get it to start, that's another
story. If you have enough time to pump the gas pedal while cranking
the engine, something is wrong.

In either case you can rule out the starter motor. I am going to guess
that you have a faulty fuel pressure regulator. When they fail the
fuel lines do not hold a residual pressure and this leads to long
cranking times while the fuel pump pressurizes the system. You could
confirm this with a fuel pressure gauge. Alternatively, if your
Hyundai is like the GM cars I am used to, the fuel pump will run for a
second or two when you first turn on the key. Try this: before
starting the car, turn it on, wait a few seconds, turn it off then
back on, wait a few seconds, and repeat this perhaps four cycles
before finally attempting to start the engine. If doing this makes it
start right up every time, you have proven my theory.

But like I said, that's just a random guess formed by attempting to
read between the lines.

Peace,
Harry

Oops, I called your Datsun a Hyundai.

the fuel pressure is bleeding down after the car sits for a while.

Nissan has a TSB for this problem.

Check the fuel pressure and particularly that the fuel is not draining back
into the tank - per testing instructions in factory service manual.

If that is not the problem, check for proper operation of IAC valve and PCV
valve and associated air passages (engine idle air supply).
