Switch the injector connectors to see if you get fuel. If so, check the wires more thoroughly for continuity. Sometimes the wires break inside the insulation/cover and visual inspection will not be effective. Good luck.

are you sure its not getting fuel? even with only one injector firing, the front intake valve reversion into the intake should put some fuel in the rear cylinder, and it should go pop at some point. did you try dribbling some fuel into the plug hole? might be bad wire or coil issue or a bad plug, where the spark energy is arcing to ground instead of across the plug. just a thought.

No ecm data is showing up at all? Is the battery voltage ok? Maybe it is low enough to screw up a connection to the ecm and cause funky problems. Just a thought, have heard that low voltage can cause strange issues and some programs need something like 11.8V connect to ecm.

When I picked up my '00 in December, it only ran on the front cylinder.

Check your coil and your wires. Specific resistance called out in the service manual.

Also might be something as simple as a bad cell in your battery.
