1) If I see sparks from all of 6 terminals, can I eliminate ignition coil from potential culprits (of no start or hard start)?

2) If the diaphram of fuel pressure regulator holds vacuum, can I assume it's not the culprit (for no start or hard start)? Rephrased, can a fuel pressure regulator hold vacuum and still be bad?

Thanks.
