Did you run the engine for a short period of time and not warm it up?

850 engines would suffer from LAWN MOWER SYNDROME - you moved the car to get the mower out and then the car would not start. It would crank good,but no fire - it might even crank faster!

Do a search on this. - it happened to me.

There are several theories on this

My theory is this - when the engine first runs, the first things to get warm are the exhaust valves - they stick in their guides and you lose compression.

one technique is to crank and crank the engine, it may sputter several tines and eventually start.

If you have it towed to a dealer, they will start it then change the plugs and the oil and filter - fuel fouled plugs and fuel in the oil.

We had a family rule - You never start a white engine unless you are going to warm it up..
