I apologize if I implied that having a mis-positioned distributor might cause the injectors to not fire. What I meant to say is that a mis-positioned distributor would prevent the engine from running because the timing is so far off.

With the AFM disconnected, your injection system will not know how much air is going into it. Look to the WSM for the AFM test resistance measurements that are taken between the various AFM connectors. These measurements are easy to do. Consider performing them with the AFM on the bench, and then perform the same measurements with the AFM in the car by connecting your VOM to the plug to the ECU. The AFM measurements should be the same at both points. If they are not the same, then you have a wiring issue.

According to other references TempII disconnected (or a wire break) will cause the car to run extreme rich. Perhaps(I'm guessing here) what is happening here is that the injectors are fixed full ON? Is your noid light solid lit?

There are test measurements in the WSM for the TempII. Please check this at both the sensor and at the ECU plug.

I understand your frustration here and look forward to hearing what the fix turns out to be.
