pull a wire and ground it via useing a screw driver at the end of the spark plug boot to check for spark / if their is no spark / ignition control module / there is also a crank shaft position sensor / located on the back side of the motor under the coil packs / pain to get to / also the nuetral safty switch / to check the neutral safty switch diconnect the big harnest at the neutral safty switch put a fuse tester to the yellow wire / have someone turn the key / with the tester grounded the light should come on / now we know the ignition switch has power going through it. if there is a no power at the yellow wire / bad ignition switch / does the car have a relay located at the top of the radiator core support (up by the radiator looking down drivers side)if it does not gm will install one for free / if there is / look for the purple wire coming out of the relay and Follow it down to the starter / reconnect the neutral safty swtch / touch the small S (the smallest screw) terminal on the starter soilenoid / have someone turn the key forward check the light / this will detemine if the relay is good / CAREFULL NOT to touch the big starter wire with the little one it will jump the starter / I HAVE THE SAME CAR / Hope this helps

sounds like either your fuel pump went out or you have no spark going to your spark plugs check and see if you have spark first if so then open your gas cap with your ear next to the filler tube have someone turn key to run possition you should hear a humming noise for a few seconds if not then your fuel pump went out

Check your fuel pressure at the shredder valve. If you don't have a fuel pressure gauge, you can get a loner tool at Auto Zone and get the proper fuel pressure readings you need for you car. I don't know which engine you have and the different engine's have different readings. Good luck and hope this helps on check the fuses, it could be a simple as that.

That car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.
Testimonial: "the check the ground was a good suggestion, i will do that at my first opportunity"
