Question about 2006 Lincoln Navigator
Turning over is cranking
You mean will not start !!
Given it is 5 years old
Change the Spark Plugs,if you haven't
Change both front O2 Sensors at 100,000 miles
Clean the MAF Sensor --CRC MAF Cleaner
Next -- TEST the TPS Sensor on throttle body
It is replacable. (2) T20 Torx screws and a hair
dryer to soften the thread locker
You may be loosing the throttle position on start up
Then check fuel pressure, at the fuel rail on engine,
also if your not going to work on it yourself, have the TPS
and Fuel Pump looked at with an Oscilloscope
The fuel pump may be going bad
