How did you determine you're getting fuel? Do you know whether the
injectors are pulsing?
You'll need to check to see whether you have spark. Without that
information, the list of possibilities is greater. To check, pull one of
the plug wires out of its hole and stick an old spark plug in the end and
lay it on the valve cover. (Make sure you haven't spilled any fuel in
this area if you've disconnected the fuel line to check for fuel). Then
crank the engine. If the plug sparks, you have spark.
I presume your engine cranks based on your description. If not, that's an
important detail.
You might also check your cam timing. If you haven't replaced the timing
belt yet, it's about time for it to give up the ghost.
Along with the timing belt, other possibilities are a defective
alternator, a weak battery, and a defective crankshaft sensor, in addition
to a host of other sensor-type issues.
