okay, so i have a 2014 mustang v6. The car ran great until i went to start it up the next morning when come to find out just cranked but not starting. Since then i have replaced with a new OEM fuel pump; all fuse's checked, battery's new with a steady hold charge of 12+ volts. just running out of places to look for answers. Car will just crank crank crank without starting. I am not sure if it has something to do with the PATS, disabling the fuel system from operating if thats possible? does anyone have any insight on how to check on these motors for a fuel pressure? i don't see where i can hook up under the hood to check for fuel pressure. i can't seem to find anything on the newer mustangs with these problems. Their isn't any inertia switching in the trunk or under the dash. Any way to check the PATS? i have also tried once a brief spray of starting fluid into the throttle body which allowed the car to fire up for a moment. any HELP would be greatly appreciated!

Car has mods:
In-tune tuner which was tuned back to factory settings.
Airlift autopilot digital air ride setup
Borla atak cat back exhaust
BBK throttle body
Airaid Intake
SR performance line lock's
RE Sound system in the trunk

Stock tune with an AirRaid intake and BBK throttle body? How long have you owned the car?

The fact it started up briefly with a shot of starter fluid makes me think it's intake related like a leak or the car needing a tune.

Airaid is usually one of those that can be had with or without a tune but, without a tune requires that the tube restricter be put in place to reduce air volume and not throw a code or cause problems. I think the BBK also requires a tune?

But before even when the car would run it would still run off a factory tune at times when i would update my tuner. It was on a different tune that diablosport made. (Regretting not going with sct) but aside from the point it ran indifferently as far as starting from factory to diablosports tune. But your options could be possibilities. I also do not have any codes so it says from multiple readers.

The bbk TB does not need a tune..it definitely sounds fuel related since a spray of starter fluid caused it to fire. If it was the PATS, it wouldn't have had any effect. You are on the right path with fuel system.

have you tried reinstalling the tune? Is the check engine light on?
