years ago we had a 96 sho that would do the same thing. it usually happened when it would it was pulled into the garage after washing it.
first time we called AAA and they got it started.
after that, i would just keep cranking it, within reason, i think with the gas pedal depressed. there may be something about a no start situation in the owner's manual.
when it fired, it would blow out some smoke, but was ok after that.

Yeah I haven't seen anyone on the Lincoln forums that have done the 4.6 swap. That may be because of the computer issues, though.

You'd be better off adding a supercharger or swapping in a Jag S-type regular or supercharged engine.

Bruce's problem happened almost 2 years ago. He just became the proud owner of an ecoboost 365 hp MKS.

Actually, it never happened to me or my LS. However, years ago when I worked in the service department of a Ford dealership, we would have cars towed in that would not start on a bitter cold morning. Occasionally, they would be so flooded by the owner pumping the accelerator that the oil would be washed off the cylinder walls and there would be little or no compression. After getting them started and restoring the thin oil film on the rings, the compression would be fine.
 
Of course, my experience was before the days of fuel injection. I don't know if could happen with today's cars or not but I think the point I was making 2 years ago was that it might be possible.

I have taken a long time to tell you how correct you were about my problem and the dealer's diagnosis. (See post 1) The car has started fine since I had this problem, still burns no oil and runs great. I now have 167,000 on the car and it feels like its just now broken in. I notice others have also had a dealer tell them they have no compression in some of their cylinders and am wondering if their cylinders have also somehow been washed of a little oil. Thanks for the help.

Glad to hear everything worked out!! It always pays to consider the simplest things first before diving into the wallet. I really liked the 3.9 in my LS. It never burned a drop of oil and other than coil failures, it always ran like a champ.

engine won't start and leaking coolant from manifold pipe by donnanharold

When I tried to start my car it made a sound like a car makes when someone turns the key on a car that is already running. I turned it off then tried again. Now it makes a single click and all the gauges jump to the right and then back down. After this I noticed what appears to be coolant leaking from the driver side manifold pipe in the area of the front seat. It is leaking at a connection from the bottom. Doesn't appear to be wet on top. Is it possibly the starter went out? What about the leak. No water in the oil and the car ran fine earlier. Didn't overheat or act up at all. We have spent so much on this car. Please say this doesn't sound as terrible as we fear.

I'm guessing dead battery. The leak may be totally unrelated. Try jumping it and if that doesn't work then it may be more serious.
