How to change spark plugs on saturn L300 twin cam 2003 model

SOURCE: Change spark plugs on 3.0 2003 Saturn Vue

This is a outstanding question!!! The plugs or wires are not visible from the top or sides of the moter. You just can't see em'!!! You have to remove the large black plastic air intake. Then remove the intake manafold(not too hard to do) to access the spark plugs and wires. Also: After removing all the black plastic air intake stuff, you'll have to remove the coil pack (long black plastic thing that says "Ecotek" on top). The coil pack is removed by disconnecting the wire connector on the driver's side end and then removing four bolts. To lift off the coil pack, you'll have to pull upwards firmly and evenly from both sides, because the spark plug boots or wires are holding onto the spark plugs as well as the coil. With the coil pack removed, look down into the silver channels - there's the plugs. To remove, you'll need a plug socket head and a socket wrench with long extension. To replace the plugs, I use an extra or old spark plug boot to hold the plug and get it started turning into the engine threads. Good Luck!

Remove the plugs, make sure the new plugs are gapped to .040, put anti-seize on the threads of the new plugs, then install them and tighten accordingly.

Start with the simple by replacing your fuel filter, but most likely it's going to be your fuel pump that will need to be replaced soon. It's common for the fuel pump on the Saturn's to go weak after a few years, the piston and the cylinder sleeves after a few years wear and the clearance is much grater when the pump heats up.
The extra clearance will cause the fuel pressure to drop just enough to keep the fuel injectors from working. Once the pump has cooled down enough for the piston and cylinder sleeves to create enough fuel pressure, your engine can run again.
You may get luck as mentioned to start with the simple and replace your fuel filter first, then the fuel pump if that did not help.
Thank you for using fixya and good luck
