[QUOTE="scott degroot, post: 949762, member: 66039"] In this case the engine is probably flooded. It is not uncommon for vehicles that are cold started and then immediately driven very short distances and then shut off to flood. The coolant temp sensor doesn't accurately reflect the temp of the engine in this scenario and then when you go to restart it after a brief period of time the pcm comands too much fuel and the vehicle floods but when you floor it the pcm goes into clear flood mode and cuts down on fuel delivery and then the vehicle starts. This is once possibility. Another possibility is that there may be an injector leaking and causing the engine to flood or perhaps even a ruptured fuel pressure regulator. [/QUOTE]
