    Test the fuel pressure.

    First thing turn the key on into the position just before start and go check the fuel pressure on the little bleeder valve safe it squirts fuel. If so move on remove a spark plug wire and see if it has spark. Before you get in too expensive diagnosis has spray some WD-40 into your locs and open and close your doors with the key a couple of times if the theft switch hangs up inside the door your car will crank but it won't start. Believe it or not this fixes about 60% of the no start on those cars. well after you figure out why your car won't start no fuel or no spark then you can start tracing back components and figure out what's bad.

    Spray some Starting Fluid in the Intake to see if it's a Fuel Delivery problem. If it starts the Fuel Pump Relay should be checked and then you need to Troubleshoot it if it isn't that. A Repair Manual will have a No Start Guide. or call a Mobile Mechanic. Don't just start replacing parts and guessing. Get a Test Light if you don't have one, you'll need it for ANY Electrical Troubleshooting. A Multimeter would be good too.

    I would suggest you find out why it doesn't have either fuel or spark or why you might have both but not in the correct order

      Bad crank sensor can kill the spark. Not the Cam sensor. But really.. guessing is futile.
