Message	FWIW I once had a fuel pressure check valve go bad on a z. It had to be cranked, and cranked, and cranked before it would start because the check valve was not holding line pressure. Car still ran fine when it finally started but it would take about 20 seconds of cranking until the pump would catch up.
