What is the rail fuel pressure when cranking? Have you checked for injectors firing with a noid light when cranking? When you checked for spark did you check all of the plugs?

If the rail pressure is okay and you have injectors firing and spark I'd suspect a large intake leak.

Simple test: Pull the intake boot and fire a short squirt of Easy Start into the intake - turn the engine over.

Does it start and run for a few seconds ?
