Rough start, idles up then dies

[SW0_KJ_JEEP]

I got this 2006 jeep liberty 3.7l v6 and it's been having rough starting issues and issues keeping started

Here's what I've changed

Fuel pump
Crank sensor
IAC Valve sensor
Throttle body
Throttle body position sensor
MAP sensor
Plugs and Coils
Alternator

Please help I will attach a video soon if it uploads faster

Have you checked for vacuum leaks?

Disconnect the vacuum hose attached to the throttle body..... And see if it helps..

I've checked all the lines i could find and no leaks

I'll try it

Try giving it some throttle while starting. When I try to start mine warm, I sometimes get a similar issue (see the links) despite several parts replacements (and even a new engine). I've never seen the issue when giving it some throttle while starting.

I don't see a fuel filter on the list of replacement parts.

The alternator has been changed since these clips but still no difference

Try giving it some throttle while starting. When I try to stay mine warm, I sometimes get a similar issue (see the links) despite several parts replacements (and even a new engine). I've never seen the issue when giving it some throttle while starting.

When given any throttle it dies

That sounds similar to mine. Nothing solved it for me except giving it some gas as I start it.

We got it to start after spraying gumout through the schrader valve on the fuel rail so probably was a blockage from sitting for so long or bad fuel from previous owners

So we will be changing the Fuel rail and injectors
