Hey guys, I'm new to the forum and looking any suggestions on a problem that has me stumped with my avalanche. It has a hard start condition. It seems to be related to the outside temperature. I didn't do it all winter and started back as the weather warmed up. It starts fine if the engine is completely cold and it starts fine if you crank it within about 15-20 minutes after cutting it off.

It doesn't have an inline fuel filter or a fuel pressure regu
