After realizing that two wires o the battery poles were switched I reversed them back to their proper orientation and my ECU is now properly grounded. Also for the first time, when the car is ON and you depress the flap in the AFM the fuel pump runs which is the first time I have ever heard the pump run on its own/on a signal from the car. So we are still not getting ignition so i will retest the EF circuits and see if the injectors are getting the voltage they need.
EF 2.1 revolution trigger signal still reads 1.6v
EF 2.2 Power line circuit now reads 12.20 volts! first time that has happened - very good news.
EF 2.3 Injectors all show 12.2 volts except injector 5 which shows 11.6! First time this has happened also - very good news
EF 3.1 Starter signal 8 volts during start - seems good enough. The starter is turning after all
EF 3.3 Cold start valve and thermotine switch - reads 8 volts during start

AFM and EF Checks Dec 19, 2012
Removed the AFM and tested all the checks in the manual on pages EF-51 and EF-52.
Passed with flying colors
However there was a ground wire that had been smashed underneath the sensor that was grounding the AFM outer casing to the body which was smashed/pinched/broken. So we remade that wire.
EF-23
2.1 Revolution trigger signal - voltage is 1.6 volts during ON and 0 when key is OFF. The trigger signal wire from the negative side of the coil to the 1 pin on the ECU plug is continuous and good.
When the key is turned to start the voltage increases to 3-4 volts. I am not sure if this voltage is enough or if the 1.6 volts is enough to indicate the "line voltage" that the manual says is an indication of the circuit. -- Not sure--
2.2 Power line circuit. voltage is .15 volts and doesn't change when I turn the car on or off. Between 88a on the relay and pin 10 on the ECI is continuous. 10.8 volts exists at 86c when the car is turned on. 88z and the +pole of the battery is continuous but at a big resistance because of a large fusible link in the way.
NO voltage through the fuel relay. There is positive voltage however the ground is not continuous with the body ground. WORSE! ALL the grounds on the ECU plug and in the fuel relay have no continuity with the body ground. ALL of these grounds converge into one large ground wire the grounds directly to the negative battery terminal. SO there has to be some crack or disruption in this big ground so that all the ECU grounds don't get there much needed ground! Until this gets fixed all of the fuel injection electronics won't work and the car won't start....
Need to find this break....

Interlock system - Dec 18, 2012
Is an error in the interlock system causing the car not to start? The interlock system is either broken or is sensing something is wrong and refusing to let me start the car as it should as a safety feature.
So when the seat belt isn't plugged in on the drivers side and try to start the car there is a buzzer that goes off and beeps a few times. The fasten seatbelt light does not seem to come on.
The ignition fuses are intact. (except the defogger, AC, cigarette lighter, and catalyst lamp)
OR the interlock system has been removed since I can't seem to find either the relay or the unit!
Now that leaves me with wondering how and why I have no power to the fuel pump and the injectors don't fire even when we hotwire the fuel pump.
The fuel pump only runs when the AFM has air going past it. This is the only thing that keeps the fuel pump running when the car is started and you turn the key to run.
Looks like its time to the revisit the EF checks to see which EFI checks are giving me troubles and re-check to the AFM.
