CHEVY CRANKS BUT WONT START

Engine Mechanical problem

Hi, My cavalier wont start the engine will crank when the ignition is turned but nothing further happens. If left alone for like 6+ hours it will start for a moment and can be kept running for a few minutes if the accelerator is pressed. Eventually the engine still dies out. I have already clean my air filter and changed my spark plugs but still no response

Cranks but no start condition-do below to determine whether it's fuel or spark issue that's causing it not to start.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -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.
