Definately check as Joe says for problems with fueling ...
Also check the ignition amp / hall sender and fuel pump relay - all 3 can cause problems, but I wouldn't have thought with starting alone ... same with the fuelling too, but u have to rule them out!
Is the static ignition timing correct ?? When she's not firing does she turn over fast or slowly ??
When you're trying to start her, get someone to check the timing as she's turning over with a strobe to see if the timings jumping about or missing a beat ... hope this gets u started
