you need three things for engine to start and run: fuel spark and compression. so check that you have fuel to injector fuel rail ,spark to each plug then go from there....

Actually you need 5 things to make an engine run. spark, fuel, compression, air and timing.

If you have spark and PROPER fuel pressure then check that the timing belt hasn't broken. Again, if the fuel pump is only putting out minimal pressure it wont start. You need to know how much pressure is actually present.

If it was my job to repair this car i would start by taking out a spark plug and putting it in a spark plug wire and physically watching the spark. If the spark was blue and sharp then i would check the fuel pressure. Also i would use my scanner and check for any diagnostic trouble codes and decide if that could be an issue. You might have a bad or weak coil. Please check that also. Make certain that the timing belt hasn't broken, if it has then you have a problem as these Neon engines smash valves into pistons when the timing belts let go.
