Navigator Poss Timing Chain Issue
Have a 2001 Nav with 112,000 mi......runs great...very smooth..no unusual noices or performance....just returned from 600 mi trip.....pulled into driveway parked....no unusual noises or performance....tried to start next morning and eng would barely crank....engaged ignition again and barely cranks...tries to but it's like a 1/4 turn...making an ugly almost scraping sound for just an instant...first thought prob was battery not able to crank engine...battery checked out fine...then thought prob starter....replaced starter...still same prob....I'm wonder maybe timing belt issues but no symptoms leading up to failure if that's what it is...very strange....any thoughts would be greatly appreciated........Dave

Navigator Poss Timing Chain Issue
Alloro,
Thanks much for your reply......I attempted to jump and when unsuccessful I removed battery and took it in to be tested....Tested out pulling 820amps...battery less than 9 months old and a quality Interstate unit....so that has definitely been eliminated.....the symptoms all lead one to conclude starter but unless I installed an already defective starter then that's unlikely....
Any ideas?

Remove the spark plugs and turn the engine over by hand using the bolt in the crankshaft dampner. You may have a leaking injector. You should be able to find it by looking into the sparkplug hole to see if there is fluid, fuel rising in the hole. If that's the problem vacuum the fluid out and replace the injector. Just be sure to check to be sure it's gas and not coolant. If it's coolant there are major problems.
Good luck with it and let us know what you find.

Navigator Poss Timing Chain
Thanks Moto for the suggestion......I'll do that next.....Wondering though if I have fluid in the cylinder indicating something very serious....some kind of engine breach or failure....wouldn't there have been some symptoms when engine was running just minutes prior?
Also.....someone suggested turning on lights with bright on and trying to crank again watching headlights to see if they almost go on verge of out during crank.....They did which he says sounds like I've got a bad ground somewhere from the battery to the engine wherever that wiring attaches...
I'll also be locating that wireing for poss bad connection.....does that sound valid?

If there have been no electrical issues in the past I would first check the mechanical as I suggested earlier. If the cylinders all check out clean I would then expand my search to include the electrical. If one or more cylinders have fuel or coolant in them the engine would do the same as what you described. It would be hydro locked if there is enough fluid present.

Thanks for all who have responded and you Moto for continued follow-up..
Found the solution......My AC compressor cluch failed and the bearing siezed preventing the serpentine belt assemply from turning across the pulley attached to the clutch.....thus the engine would not crank......explain the strange metal against metal sound when I did attempt to start the eng....
Probably at the bottom of the list of what logically should have been the culprit.....

It would only be a small fire at most, in any case.

The vacuum's intake is atomizing the fuel, mixing it with air and creating a fuel/air bomb.
All it needs is a tiny ignition source.
Fuel+Oxygen+Heat = kaboom!
Oh, have an Class A/B/C extinguisher handy too, preferably out of the blast zone.
I doubt Dealerships use the common shop vac for fuel spills. If they do, better not tell the insurance carrier about it.
A small, non ferrous hand pump or siphon might be a better idea.
Safety first.

A better idea would be to use a handheld vacuum pump, the kind commonly used to do one man brake bleeding.
