The list of possibles is pretty endless, but here is a wierd one:

Try a new fuel pump relay. 
I had a problem where the relay would not close properly the first time - on 
the first twist of the key the motor would just crank but on the second twist 
it would fire right up.
My relay was easily fixed just by taking apart and tweaking contacts.
An easy test is to put a volt meter on the B+ wire of the coil(s). The coils 
and fuel pump get power from the same relay, but from different contacts inside 
the relay so it is possible for example for the pump to get juice but not the 
Also measure fuel pressure.
