I would say first to check your fuel pressure. Jim talked recently about
installing a switch that will run the fuel pump from the switch, so you can
pressurize the fuel ring before trying to start.  I would say this is your
best bet.

In my personal experience, if I do not turn my key on and off about ten
times (or more) no amount of cranking will start my car.  I have to
pressurize the system and then she starts right up.  And again from
experience, cranking does not increase the amount of fuel nor does pumping
the pedal, you must first get it up to 30psi then try to start the car.  You
could experiment,  I attach my fuel gauge to the ring and leave it clamp
there.   You could then get the pressure cold then turn the key a couple
times and check it etc.  If you do this a couple of times in different
circumstances you can deduce what is going on.

But installing the switch is probably the easiest fix.
