Default 07 mustang gt 4.6 turns over but won't start

Car has been giving me problems for a month or two now. It turns over but won't start. I had fuel pump replaced at a ford dealer like two weeks ago when it was doing it. But It just started doing it again yesterday and won't start. Lights radio all accessory work car will turn over but won't start. I have tried a battery charger it will fully charge up then it doesn't help. The car doesn't start when ever I let it sit for like 2 nights . I don't know what else to try.

I would try a short shot of starter fluid in the air filter and try to start it. If it starts or at least attempts to start, fuel supply is an issue. Return it to the dealer for the pump again I would say.

I can hear the fuel pump turn on when I try to start it.

Have you checked for any diagnostic trouble codes (DTC)?

...so what's the battery charger reading when you connect it to the battery?

Does it exhibit the same problems before/after you put the charger on?

Have you tested the voltage on the alternator?

This sounds oddly familiar to what happened to my step brother this past weekend. Same symptoms you are describing.
We unhooked the battery for 24 hours, then jumped the car and it turned right over. Went to Advanced, they tested the charging system and found nothing out of the ordinary

Ive had pretty much everything tested on it at a garage. It will read low then it will fully charge and still won't start. And I'm not for sure on the DTC I'll check at the garage with that. It just so random when it happens tho. I have a new fuel pump switch coming in tommaro mornin and I'll see if that's it.

Just because the pump runs does not mean fuel is flowing.
