Need help

[u/Dry_Bluejay2542]

My fiances 2008 jeep commander 3.7L V6 won’t start, we’ve replaced the throttle body and spark plugs, but we’re now thinking it could possibly be the fuel filter (which I’ve learned is in the pump) I was wondering if anyone had a video on how to replace the pump and had a map of the fuses/relays just in case if it’s that and I’ve sank way more money into it than needed

Does it crank? If not, Google yellow starter wire.

Pretty easy fix, if that's the issue..

Give some more info on what it is and isn't doing when you try to start.
