Asked by Feb 28, 2016 at 01:04 PM about the 2000 Lincoln Navigator 4WD

Question type: Maintenance & Repair

I have a 2000 Lincoln navigator with a 5.4L V8. On way home it died
on me and won't start. It will just turn over and does not try to fire at
all. And when it turns over it makes a weird high pitch whining sound.
What could cause this ?  I watched as it was cranked over and engine
is turning over because all the pulleys are turning.

I've heard it could be the anti theft system, the timing chain or the fuel pump.

I have the same trouble , I put a new fuel pump and check for spark , and it has fuel when I put it on cause it comes out the fuel pressure regulator with no problem when I took it off . I think it's the Anti Theft system because the theft light keep flashing and won't go off until after a couple of minutes

So what did y'all do bout the anti theft system Please email me some answers. Shakimahw@gmail.com
