Engine wont start
Hi, I have a 2005 ford mustang gt manual 4.6l, And it wont start
It broke down about 3 days ago when driving uphill and it wont start since
I checked the inertia switch, Replaced the fuel pump, fuel filter, fuel rail pressure sensor, and the cam phasers, still no start. Last time i checked it had 15 PSI of fuel to the engine, and very rarley the car will start for about 3 seconds at 2k rpm, drop to 1000 for about 5 seconds, then stall out, I am out of ideas of what to replace or what to check, No fuel leaks or oil leaks or coolant leaks. Any help would be great

your measured fuel pressure seems low, according to workshop manual it should be at least 30 psi.

if you feel pressure is good to go, i would think about doing a compression test to verify no valve
or piston damage.
