Re: getting fuel and spark but will not start
Are the spark plugs black?They won't fire if they are coated with carbon.The spark will follow the carbon down the side of the plug insulator instead of jumping the gap.
On an engine that has been sitting or badly flooded with gas,adding a little 10w30 into the intake will restore compression that may have been lost from gas washing the rings dry. The 10w30 trick has worked for me many times.
Don't overlook correct ignition timing.

check and make sure you have plenty of fuel in the tank. gas light should not be on as long you have plenty of fuel in the tank unless you have faulty fuel level sensor. check if you getting sparks and fuel, pull wire and one plug out, ground it to the vech have a friend turn over the engine and see if you getting strong sparks. no sparks check coil having 12V, good coil, cam sensor faulty. check if you getting fuel, pulling hose from the fuel filter line, point it down ward wrapping the end with clothes covering the hose and turn the engine over, see if you getting proper fuel and good pressure coming out of the line using your thumb slightly cover the fuel line. no pressure or fuel, check the fuel pump, good pump, faulty crank sensor. both crank and cam sensor work the same way, one telling computer to send sparks to the plugs and other turn on the fuel pump.
Could be bad crankshaft pisition sensor, usually is that sensor, or at least some type of sensor. All a car need is spark, fuel, and o2. So if you have all of these things, than you most likely have a bad sensor. Have you pulled each plug individually and tested for spark? If you got good spark, and you are getting plenty of fuel to throttle body, than you may want to check your timing. You can test all your sensors and wiring with an ohmeter to check resistance. Place one probe on one side and the other on the other side while in OHM setting. If everything is good, you will get a reading, if the sensor is bad than you won't get a reading.
the three things an automobile has to have to run are compression, fuel, and fire. I think you need to check the firing. I would remove one of the plugwires and insert a screwdriver into the end of the plugwire, have someone turn the engine over while you hold the screwdriver about 1/4 inch away from metal on the engine if you get a spark then it is firing and you need to move on the next option. I hope that helps!
This to me sounds like it could be the fuel pump but first I would check the simpler solution and make sure your alternator is good because if your started turns over fine but the car wont start the next part to check would be for me the alternator.
