Hi dsfunction69. Have you checked for spark from both coils? Also, have you checked for fuel pressure. The fuel pump will run for one second after you turn on the ignition switch. Have you listened for its hum? It must also run during engine cranking. If you don't hear the pump run for that first second, bang on the bottom of the fuel tank while a helper cranks the engine. If it starts up and the engine runs, the pump will rarely quit while it's running.
If you're missing spark from just one coil, the Check Engine light should be on. If so, have you checked for diagnostic fault codes? If you get a code related to cam and crank sync, first check for a jumped timing belt. At one tooth off, the Check Engine light will turn on. At two teeth off, the computer will shut the engine down but you will often have spark from one coil. At three teeth off, the pistons will hit the valves.
If you do have a cam and crank sync fault code but the timing belt is in correct time, suspect a broken dowel pin between the camshaft and sprocket. That only applies to the single cam engine.
