No spark? Usually that means the crankshaft position sensor has gone out. It usually happens while you're driving too, out of nowhere. If you're lucky, after the engine cools a bit (20-30 minutes) it will start again and then shut off after it runs awhile. Another crippler on the 2.4 that I have ran into is the Camshaft position sensor. This will go while you're driving too. The one I worked on would start up and run for about 2 seconds and shut right off like clock work.
