This might be a bit complicated. Basically an engine needs three things in order to "run." Fuel, Compression and a spark (at the proper time). How do you know that the fuel pump is working? To possibly save some time, check the fuel pump fuse and relay first (in fuse box underneathe the back seat) Check the fuse with a test light (both sides). The relay should click when the ign. Switch is turned on and about two seconds later it should click again as the pump turns off. Sometimes a pump might sound like its' running, but in fact it might not be pumping any fuel.
If you or your significant, mechanically inclined other, is able. Try this. Remove of pull back the intake smorkle enough to spray carb. Cleaner (or other flammable liquid) into the throttle body; a small amount will do. Repalce and secure the snorkle. Try to start the engine. If it starts, it will only run for a couple of seconds, but this will let you know that the engine is not receiving any fuel from the pump. In this case, check for power reaching the fuel pump, fuel pump ground, check gas filter and make sure fuel lines are not clogged. If everything is good and still no fuel from pump, repalce pump (pump is accessible through a port underneath the carpet on the right side of the trunk compartment near the back seat.
If the fuel pump passes the test, the problem is probably spark or compression related. Post your results. There is more help if you need it.
