2009 5.3 - Raw Fuel at Startup

[Snow White]

Remoted started the truck and did a whiff test by the side exit exhaust and pretty sure I figured out the leak is internal... it just started doing this last week so it's still cranking fine but I presume, I have a sticking injector at 97,000 miles? I suppose I need to take it in to have a leak down test done because it's a pretty strong leak based on the odor around the truck lol. Maybe I can pull the injectors and use jumper somehow to try and activate all of the injectors manually?

 

Taking suggestions.

Problem solved, spark plug on No.1 was so loose i could see the plug wire vibrating with the truck idling and turned the plug out by hand... it was loose because i pulled it a few months ago to check the plug and I must not have tightened it enough... oddly i had no misfire or anything so it must have been in there just enough to left fumes by.
