Engine Mechanical problem
1997 Pontiac Sunfire 4 cyl Front Wheel Drive Automatic

we park the car for the winter and now it's time to put the car on the road but it doesn't start anymore.the fuel pump doesn't work but if i plug it directly on the battery is works but the car still don't start. I checked to make shure the battery was correctly grounded, it is, i checked the computer, it ok, all the fuses are working correctly. can you give me a hint on what it could be my problem?

Do below:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
