01 Dodge Dakota 4.7l v8, 150k
If the truck sits for more then 10 minutes, upon starting it, I have to crank on it for awhile. Maybe 5 or 6 secs. It will then usually start, however, if it doesn’t, I stop for a few seconds, and start again, and it will fire up on the second go around. Upon it starting, the engine lets out a puff of black smoke, and you can smell gas. It runs rough for a second or two before it clears up. It almost seems like the engine is flooded. It does always start, and the truck seems to run great. I checked for codes, no codes. I’m thinking I should start with a fuel pressure test? See if the fuel bleeds off quick?
I looked at some live data from my simple scan tool I have, and everything looked “normal” (at least to me) except my LT FTRM 2 is showing -14%. So my thinking is maybe I have an injector that is stuck open? Maybe the fuel is bleeding off an injector, and that’s why I have the long start and maybe that’s why the rich condition exists?
Am I thinking through this correctly? Looking for some confirmation or redirection. Other then the fuel pressure test, where should I start from, knowing what I know.
Thanks for the help

Installed OE injector yesterday and to my surprise it fixed the issues. No longer have a long crank on starting and the fuel trim numbers look great. I’m just shocked that one leaky injector could cause so many problems and such severe problems. Glad I didn’t just throw parts at it. Thanks for help.
