[QUOTE="Yardsale , post: 1018425, member: 58988"] There is a known fuel pump check valve problem where it won't hold fuel pressure in the system when the pump is off. It is associated with heat buildup on the fuel delivery near the engine. It's sort of a vapor lock condition. A "test" (such as it is) is, when this occurs, cycle the key to run several times leaving it in that position for 10 to 15 seconds each time (allowing the fuel pump to run several times and pressure the system) and then try to start. This noted, typically allowing it to sit for 30+ minutes would be enough to cool and lower the vapor pressure such that that pump could pressurize on one start cycle, so this may not be the problem (but - the "test" is easy and free (and where ya going anyway?)).
