Sounds like you're making good progress. Thank you for updating us. I hope you're successful since I seem to have a similar problem. I just had a question/clarification on the terminology you're using - when you say pin 1A, do you mean pin 1 on pulse module A connector? Also, what do you mean when you say "used a jumper to keep the engine going" in your second post? A jumper from 2A to ground or something else?
Thanks, sincerely
Jerry
PS. I disconnected connector C207, and checked the continuity between it and the SLA connector. That all checked out. Next, I'll check the continuity between C207 and the PCM. The service manual has two errors with regards to the C207 connector- one is that the C207 connector is actually shown in figure 3 not 2, and in figure 3, C206 and C207 labels are swapped. I'm working on taking the TCM apart to see if any transmission fluid is in it - the wires feel oily, but that probably is from the electrical tape, but I want to be sure.
Jerry; When I said pin 1A , yes, pin 1, A connector of the pulse module. I have now connected a momentary contact switch for safer testing between the 70 ohm resistor on pulse mod pin 1A and grnd.
The jumper I installed to keep the engine going was across the fuel pump secondary circuit, pin 2 and 3 on RCM connector B.
I have since ran a speaker wire from the primary side of the fuel pump circuit RCM pin 3 connector E and Bat neg, inside the car to a volt meter to monitor if the PCM tries to turn the fuel pump on. So far, the PCM has not activated the fuel pump relay.
I tested the fuel pump relay circuit by applying o volts (gnd) through a 33 ohm resistor to pin 3 connector E with the key in the on position and the fuel pump relay works just fine.
So far I have 2 circuits of the PCM that are not working, engine start and fuel pump. Cannot figure out why when the engine does run under the use of jumpers.
