I have a 1998 chevy 2500 pickup with a 5.7l engine,i replaced the fuel pump and battery 4 months ago, it ran fine until 3 days ago.I went to start it and nothing happened so i jumped it and it started right away, so i left it running for about an hour. Then went to start it the next morning and nothing happened,so i boosted it again,it cranks but won't turn. What is next?

Check the battery condition and connections-could be a short that's draining the battery overnite

Check what's missing fuel or spark-Do below

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,Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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.
