It could be a fuel problem or an electrical problem.

Remove and clean the 25 amp fuse in the holder on the driver's side on the inner fender under the hood. Replace and try again. These are prone to corrosion over time. Check the fuses in the fuse block inside the drivers side door that operate the intank pump and the main pump. This are identified on the cover you remove to access the fuses. Clean these (and all the others in there as they are prone to corrosion as well. Still no start?

Check for spark at the plugs. Remove one spark plug wire and insert a metal device that will make contact with the clip in the boot and extend out of the boot. Hold the metal device close to the engine block and see if you have a spark when you crank it over. Spark there but still no start?

Spray some starting fluid into the intake. The easiest way to do this is to remove the tube from the AMM to the throttle body and press the accelerator to open the throttle plate and spray starting fluid into the intake for about 3 seconds. Replace hose and try to start. If it runs and stalls after a short period you have a fuel delivery problem. Perhaps your fuelpump relay is not functioning. Use a jumper wire to jump from the fuse in the fuse block that powers the intank pump to the fuse that powers the main pump. A wire with an aliigator clip on each end works great for this but a friend holding one in place works for testing. While that wire is in place try starting the car again. If it runs the next thing would be to resolder the fuel pump relay (or relace it).

This gives you some things to work on for the next couple of hours. If one of those fixes it great if not I guess you should post back with the information on what you have done and what you have found out. Good luck.
