Check spark and valve timing. Check egr, check for vacuum leaks. Use a spark tester. You could use a known good spark plug, break the ground electrode off, the spark should easily jump the gap to side of plug. If it won't, the spark isn't good enough. Just my opinion.
Try to see if system is running rich or lean. What is the 02 sensor signal doing, if it will run?
