Trouble codes 301, 02, 03, 04, 05, 06 are all for cylinder misfires. That's every cylinder. Okay. Are there any other codes? Also, have you checked fuel pressure drop off? If you have the van there, try this. In the morning, cycle the key from off to on 3 times. When it is in the on position, count to 5 and then continue with the cycling. Basically, when you first turn the key to on, the fuel pump is to prime the system and build enough pressure to start a cold engine. However, it will only prime for less than 2 seconds. If the pressure is dropping off to 0psi due to a leak, leaking injector, bad one way valve in both the filter and fuel pump. It could make it difficult to start. Once the engine is warm and has started, the pressure may take time to drop off. Thus, it starts easily. Also, pull the vacuum hose off the pressure regulator and see if there is any gas getting into it. Finally, see if you notice any black smoke from the exhaust when it starts. I will do more research and look for TSB's regarding this issue.
Let me know what you find.
