Unless you have reason to suspect a specific component, it's often best
to check the easy things first.
Check the fuses, particularly those associated with fuel pumps,
injectors, and the ignition system.
Pull a plug, re-attach pug wire, lay plug on metal surface, crank, look
for strong spark.
Can you see any valve gear through the oil fill hole? If so, crank and
look for motion, indicating that the cam drive belt is still in one
piece. If you can't see much through the hole, you may need to pull the
valve cover, or a cam belt cover, whichever is easier. A useful trick
is to pull all the plugs (to kill compression), put the car in neutral,
then use a wrench on the power steering or alternator pulley bolt to
slowly turn the engine.
Most fuel injector rails have a bleed bolt that you can loosen. (Crank
car to pressurize first.) If doing so doesn't get you a few tablespoons
of fuel, the pump, filter, or pressure regulating system may be borked.
(You don't want to disconnect the whole line!)
