[QUOTE="Flyer58, post: 434896, member: 18629"] Check the fuel pressure at the fuel rail and see if it holds pressure after the key is turned off. It should hold for 10 - 20 minutes, I don't recall the spec's but thy can be found in the reference section here. It sounds like it's low fuel pressure maybe from the pump or filter. Vapor locking is rare unless the fuel lines are up against the exhaust. [/QUOTE]
