Answer
Hi Nick -

Have you checked if there is fuel being delivered to the rail? If so pressure?

Have you checked to see if the plugs are getting spark from the coil? Remove one plug boot, insert a screwdriver, wedge it against the terminal inside and hold the screwdriver shaft 1/4" away from any metal surface of the engine while trying to start it. There should be a spark jumping between the 2 surfaces.

Have you also cleared the codes and see if the same ones return?
