Okay .. had the EXACT same problem - word for word .. turns out, that my positive battery cable was corrodid badly.. the ignition switch wasnt getting any power or signal - so it didnt know the trans was in park, so it locked the key in place... and all power cut off obviously because no juice was going thru the cable.
Apparently however.. you will get almost the exact same symptoms if the ignition switch burns out... so first test the battery cables themselves.. if they are fine .. then plan on replacing the ignition switch.

Ok guys, let's fix these things here!
Just went through this myself, so do the following:
Go to your local parts store and buy a Haynes Repair Manual.
You need to read the book first, learn how the ECM (Electronic Control Module) works. You'll see that there are alot of sensors and components that make up the fuel emissions bologna.
The nice thing about this system is not only does the ECM control all electrical functions, it also trouble-shoots it's self. When a component or sensor goes out, the ECM stores a code for that event in it's memory. You can use the Haynes Repair Manual to put the ECM into diagnostic mode and thus read any codes present.
So, all that's left is replacing what the EMC tells you too! :) Good Luck!

Honestly it's probably just dirty spark plugs. Did you pull any of the spark plugs and inspect the tips for build up? A couple things to remember:
1.) If the timing chain broke, the valves wouldn't be opening so you wouldn't have any air coming out of the exhaust during crank. You said it smells like you're getting fuel, so I'm assuming that means you're smelling the exhaust fumes, right?
2.) The crank sensor tells the ignition system when to send a spark to the plugs. If you're getting good spark, it's unlikely that the crank sensor is faulty.
If it's too soon for spark plugs to need replacing, check your sensors. A faulty oxygen sensor for example could cause your engine to run 'rich', resulting in faster crud build up on spark plug tips.

Try checking the exhaust flow when someone else is pushing down on the gas petal.The farther the petal gos down,the more exhaust should be coming out. I replaced my catalitic convertor at 44000 miles, it was clogged. I had them install a high flow type.
