CAR WON'T START

2003 Saturn L300 • 6 cylinder FWD Automatic • 115,000 miles

2003 saturn l300 v6 turns over but doesn't start. Fired the first couple of times but never started up. Tried to switch the modules in fuse box under the hood and that didn't help either. Has been losing gas mileage the last 6 months

**Cranks but no start condition: 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.
