Here's my "checklist" for no starts:
There are 4 things needed to start (assuming the starter motor is turning the engine over adequately): Air, Compression, Spark (at the right time), and fuel (in the right amount).
Because air and compression are not usually the problem, start with the other two:
Is it getting fuel? What is the fuel pressure? Are the spark plugs wet? Will it start on starting fluid or by squirting a little gas into the intake? Are the injectors "firing"?
Are the spark plugs firing? Multiple ways to check, I usually just start by putting my timing light on a spark plug wire and see if it fires.
