A PO303 is a cylinder 3 misfire. It is most likely the cause of the PO316. The 316 just means that the PCM senses a misfire at start up (within the first 1000 revolutions of the engine). You need to check cylinder 3 to make sure the spark plug is good, the coil is good, and it is getting fuel.

Check it out and let me know what you find.
