Wondering if our fuel filters have a check valve that is supposed to hold pressure in the fuel lines and that check valve isn't working, allowing the fuel pressure to drop. That would explain why it take a crank or two to get started.
First couple of cranks to build up fuel pressure then start after pressure is up.

My thoughts without being there to check.
the oem fuel pumps have a check valve built into their outlet.

as for quick diagnosing you guys could try this...
Fuel pressure Gauge Fittings
Marshall - Tovic Fuel Pressure Gauge

or you may be able to rent a fp tester from a local auto parts store



as for the car not firing after its been warmed up, that is usually the CPS
