BROKE DOWN

[MATRIX]

I HAVE A 2003 F-250 POWERSTROKE 7.3 ENG.
MY TRUCK WAS RUNNING FINE & IT JUST DIED(NO REASON)
IT WILL NOT START UP.CHANGED THE (CAM SHAFT SENSOR(CMP) IT DID NOT HELP. HAD IT TOWED TO THE FORD DEALER (THEY SAID THAT IT HAD NO OIL PRESSURE TO THE INJECTORS ,BUT NEEDED TO RUN MORE TESTS.
CAN THEY TELL THE OIL PRESSURE WITH OUT THE MOTOR RUNNING????

NEED HELP.

Low Oil pressure will set a code, Most likely that is what they read, it could just be the sensor.

Yes, they read the injection control pressure PID at cranking. If it's not up to around 500psi on a 7.3 it won't fire, not sure what pressure's needed on a 6.0L. Which do you have...late 7.3 or early 6.0?
