I have heard a lot about grounding issues with these cars, but has anyone had a ground issue cause the injectors not to fire??

The injectors are grounded directly from the ECU to the main relay. Additional grounds don't really change or help that. If there is a problem in this circuit, I would call that a simple wiring problem.

the ecu does ground the injectors, but there is a ground that is supplied to the ecu specifically for the injectors, from what I can tell from the wiring diagrams... it looks like its grounded on the block. check the fsm and check the signal specifications/ecu pin out. I think its 4B. Who knows.
