2008 commander help

I have a commander that just stopped running on the interstate turned off. Got it towed home and replaced the starter. Now it starts rough and have to basically flood it to keep it started. You can smell gas? When it’s started it sounds terrible just trying to start it is hard as well. Ideas?

Welcome to the forum @Roxysweetpea;

Are you receiving any diagnostic trouble codes in the Electronic Vehicle Information Center in your instrument cluster in the dash? Would be a code like P0430 or something similar.

When you say you're smelling gas, and you have to basically flood it to keep me running, it sounds like your engine is starving for fuel; That immediately makes me think you have a bad fuel line somewhere with a crack or hole in it or possibly a bad fuel pump.

No check engine codes. It’s idling rough when it does start. Like all cylinders not together or something?

Any more details on when it died? I'm confused on changing the starter as it would not have caused the engine to quit but I can see it failing after working hard to try to restart.

You should have some codes showing to help point you in a direction. That would be where I would start.
Also pulling spark plugs and make sure it turns over easy with the plugs removed to help determine if it's internal issues.
Figuring out where the fuel smell is coming from could prevent a fire and solve most of your issues as well.

Was driving normal and it died on the interstate. We changed the starter because it was just changed and thought it might have gone bad. After replacing it again it is still having the issue with not starting correctly. What would make a vehicle just shut off while driving? Itís rough and doesnít just start have to hold it to get the engine to turn over but dies quickly.

None of this sounds like a starter issue. The starter is only in use while cranking the engine when it is not running. If the engine died while driving down the interstate, that has NOTHING to do with the starter. Further, if you are able to crank the engine and holding the gas pedal down is what is required to start it, this is still proof the starter is working fine- the engine is turning over. If you aren't holding the key turned to the far right/clockwise 'Start' position then the starter isn't being used.

I'm guessing you have a Hemi since you have the Limited package- your profile doesn't specify which engine you have.
Your's being a 2008 tells me you should be safe from a dropped valve seat, also that wouldn't have happened while driving. Depending on the amount of gas smelled it could just be miss-fires, bad coils, plugs, etc. This also tells that at least the fuel pump is working.
Besides the already stated of checking for DTC codes, I know lifters can fail through almost all years of the 5.7 until like 2012 or 2013.....and this might not throw any codes, just how a dropped valve seat would never throw a code. And would have the exact symptoms you are talking about.

Yea, he/she missed that question in their user profile;

@Roxysweetpea; Please answer the user profile which asks What Power-Train your Commander has;

This is exactly why I harp on everybody to complete their user profile questions prior to posting on the forum, it helps out tremendously when other forum members are trying to help you troubleshoot your problems.

FWIW I agree with you @Wombler about it not being a starter issue, it sounds like it could be a fuel line or fuel pump problem to me, maybe even a clogged fuel filter.

On the Hemis (maybe all 3 engines?), the fuel filter is non-serviceable IN the fuel pump, so you gotta replace the whole fuel pump assembly. I still think if he/she is smelling excessive amounts of fuel that it's still being pumped. Also, they are able to get it running one way or another which requires fuel...sooo....
Since they haven't responded back with any more info, I guess this is as far as we'll get
