1. Check for Spark 2. Check for fuel pressure 3. Check compression across your cylinders It could be a broken timing belt/chain...you won't get good pressure tests on your cylinders if the chain/belt is broke, because your cam won't turn when you crank the engine, so valves won't open and close as they should when your piston is TDC.
