If it was simply a problem with the T-belt being out of time, it would affect all cylinders equally.

Also, traditional thinking is that injector timing is not particularly critical. If it was, then how does an engine run when they fire in pairs (or in 3's in the case of a six cylinder)? The cylinders certainly don't ignite in pairs or in 3's. In fact I believe that on some engines ALL injectors fire in unison.

As was suggested, testing for signal at the connectors, either with a noid light or maybe an analog volt meter, sounds like a good idea about now. You may want to test for wire continuity between the connector and the ECU. Any chance you didn't get all the grounded wires reconnected when you reassembled the engine?

Hang in there.....
