Engine Performance problem
2003 Saturn L300 6 cyl Front Wheel Drive Automatic 140000 miles

Car won't start. Sounds like going to start, but doesn't. Friend put on machine for diagnostic and came up with a code, but said Saturn has their own codes and couldn't read.

What was the code/s?

Do below to determine if its a fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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

Plugs and wires are not accessible on a 3.0 saturn engine... Removal of the intake runners are required to remove plugs and covers...
