2004 Hemi Only starts when you feather throttle like an old carburated car then won't idle

[Fullthrottle88]

Hello everyone! I'm having a weird issue with my 2004 1500 Hemi. One day after work it died on me. I was able to start it when I feather the throttle like an old carburated car. It won't idle on its own. It dips below 500 rpm and just dies out. I replaced the fuel pump and throttle body with the same issue. Before I swap out the ecm have any of y'all had the same issue?

Any codes?

I had this issue with my 2006 Chrysler 300 when the crankshaft position sensor was dying. As you indicated, the car would only start if I gave it throttle. Code P0339 if I remember correctly.
