M120 not firing injectors on left bank.

I've got a 1997 M120 that the left(drivers) bank of injectors that are not firing after having the battery disconnected for a few days. I have spark on all coils. I've swapped cam sensors, MAF's and ECU. Nothing changed. I have power to the injectors. With a noid light there is pulse, but seems very weak compared to the other bank. Any ideas. I have not changed the crank sensors. I would think if a crank sensor is bad, I would not have spark, but I do have spark. Starting to pull my hair out on this.

Update, swapped crank sensors. Still no improvement. No codes in the ECU.
