My car has hard morning starts (cranking for 10 seconds..letting go
of the key and then engine starts, very hi RPM in the "ON" postition).
It starts fine for the rest of the day. Already replaced, fuel filter,
IAC valve but no change. Some say it might be the Fuel pump or
ignition switch. Also, Is the fuel pump located inside the gas tank
or outside? Is it something i can do myself? What could be the
problem?

It could be a bad ignition switch making intermittent contact
to the ignition system in the start position.

It could be corroded battery cables, a poor battery ground, or a
failing battery. The cranking current draws the ignition voltage
so low it can't fire the coil. When the key is released from the
start position to the run position the engine is still turning from
the starter, the voltage to the ignition rises and the car starts,
running fast to clean out the fuel accumulated during cranking.
The hard starting current heals the bad connection but overnight
corrosion or battery discharge brings back the same conditions.

When cars had coil resistors, a broken resistor bypass wire could
cause this condition.

Good luck.
