After it sits a couple of days, BUT BEFORE TRYING TO START IT, put a charger on the battery for an hour, and see if it starts better. If it does start better with the battery charged up, you need to determine if the battery is weak, or is being excessively drained by an electrical "leak" somewhere, during the time it sits without being started. Have the battery checked with a load tester, if possible. The injectors in that fuel system will not squirt unless the full fuel pressure is available. If the battery is low, or the pump is weak, there will be no fuel injected during cranking, while there is the load of the starter on the battery. I can't remember the exact fuel pressure spec, you need to find out the spec, and put a gauge on it to be sure the pressure is maintained during cranking. Even a couple of pounds low, and the injectors will not inject. Also, check all battery cables, connections and grounds... body to frame and engine, etc. Almost certainly, the answer is low fuel pressure, likely caused by a weak or drained battery, or a poor connection somewhere.
