Stuck on this car have fuel to the rail plenty of spark and no injector pulse? Checked all fuses and all relays all work just fine if I manually ground each injector. I am stuck and sure its either in the ecm or a broken wire somewhere between the ecm and the injectors any help or suggestions would be great. Thanks

I would check the injector harness for missing insulation, the injectors use a common ground, so I would suspect the wiring, before replacing the ECM.

I would probably try a junkyard for a used ECM. Plug it in and see if injectors work.

If the fuses/fuseable links/relays are all OK, then the injector drivers in the ECM are burned out.
