"One thing I noticed was 2 sets of ground wires (3 grounds) on the front of the fuel rail. I'm not sure I have that."
Yes, those are the grounds Art was talking about and they are quite essential. They should go to pin 20 of the EZK (link), and to pins 5/29 (signal ground) and 17 (power ground) and 19 (code plug or ground) of the ECU (link). Not familiar with "code plug", according to the service manual, pin 19 is also connected to the manifold. LH Jetronic was also used by Porsche and Saab, so perhaps "code plug" might be relevant for them.
The ECU and ICU are only grounded through the wiring loom and not locally to the chassis for noise suppression reasons.
