If you suspect its a fuel problem best to do a fuel pressure test, you can rent a tester at auto zone and do it yourself. They also can show you how to use it and what pressure it should be. Also if you turn the key to on position you should hear a hum from the gas tank and then a click that is the pump running and the click is the relay, if you don't then the pump isent running, also chk. the fuse and relay, it could be as simple as a blowen fuse or a bad relay.

reset the ec module by disconnecting the battery for a few minutes. If that does not work have autozone do a free scan and ask them to reset the codes.

P0300 is a generic code to indicate multiple misfires throughout your engine. You do have a 6 cylinder engine and you may have to replace all 6 spark plugs and check all the spark plug wires. The other thing to keep in mind also is, the fuel injectors could be dirty or the fuel pressure may be low causing the misfire. Start with the simple and recheck the spark plug wires and try to replace the remaining 3 spark plugs that was not replaced. Good luck and hope you get your car running 100%, keep me posted and thank you for using Fixya.

Not hard at all. Seven bolts and one connector. No computer work. But you need to know if it is the front coil or back coil. Front coil for cylinders 2, 4, 6. Rear for 1, 3, 5.
