randomly lost an injector

[jilo]

After sitting for a few years I finally got my sr running in its new home, go to leave the driveway and injector two stops firing. The wires test good from the ecu, but the ecu isnt giving ground signal to fire the injector. Anybody have any ideas? Cas maybe?

Also the engine has spark in all four cyl, power at all four injectors, and ran on four cylinders for a day or so.
